Ultrasonic Flowmeter – A Complete Guide
The ultrasonic flowmeter uses the principle of transit time to help in measuring the velocity of the fluid. BSCT manufactures several products; an ultrasonic flowmeter is one of them.
Below, the detailed FAQs related to the working and installation of the ultrasonic flowmeter. All the answers stated here which being a user you might be looking for. It will help you while working with an Ultrasonic flowmeter.
What is an Ultrasonic flowmeter?
The ultrasonic flowmeter is the meter through which the velocity of the liquid can be measured. It is done through ultrasound so that the volume of the flowing liquid is easy to analyze. It requires bubbles or some particles during the flowing liquid.
Ultrasonic flowmeter doesn’t work correctly with distilled water. However, it is suitable for applications where the compatibility with the chemical, maintenance, and pressure level is low. These kinds of flowmeters are affected by the audio characteristics of the liquid, along with the density and temperature. The moving parts are not in the ultrasonic flowmeter.
How does the Ultrasonic flowmeter work?
Ultrasonic flowmeter works based on how the sound waves are used and analyzed. These signals keep flowing with the liquid through transducers. Thus, it helps contact the liquid internally, or those transducers through the ultrasound are sent in the pipe externally.
This ultrasonic flowmeter uses these transducers for receiving and transmitting as well. The ultrasonic flowmeter keeps working simultaneously so that the transit time can be measured. In both directions, the sound can be travel as well. The difference calculated in transit time directly relates to the speed of the liquid flowing in the pipe.
How to use an ultrasonic flowmeter?
You can use an ultrasonic flowmeter during the measurement of the velocity of the liquids. It helps in passing the ultrasonic waves through water, chemical, or liquids, which are cryogenic. The designs of transit time are available for measuring the gas and flow of the vapor.
In an ultrasonic flowmeter, the opaque fluids have limited ultrasonic waves. Its penetration is very close to the walls of the pipes. Therefore, it decreases the accuracy, and the ultrasonic flowmeter fails in measurement. The operations of the ultrasonic flowmeter don’t work properly when dealing the dense liquids as it makes the ultrasonic waves weak. Later, it is unable to reach the receiver.
What are the types of ultrasonic flowmeters?
There are three main types of ultrasonic flowmeter you can use are:
- Doppler flowmeter: in this ultrasonic flowmeter, the Doppler Effect is used to change the sounds traveling from the moving to the stationary location. For working, an ultrasonic flowmeter requires the air bubble to be present to start the operations.
- Transit time flowmeter: this type of ultrasonic flowmeter helps you to calculate the velocity calculated through the time carried by the signals. These signals are traveled in the two sensors. It all depends on which mode the sensors are placed in.
- Clamp-on flowmeter: there are two types of clamp-on flowmeters depends on the kind of installation done. The first one is inline, where the device is being mounted in the pipeline system, and the second one is a clamp-on flowmeter, a portable device connected with the outside of the pipe.
What are the advantages of an ultrasonic flowmeter?
There are several advantages of using an ultrasonic flowmeter are as follows:
- No path of the flowing liquid is blocked
- The liquid flows in two directions
- It conserves the energy
- It is suitable for measuring a large amount of flowing liquid
- There is a risk regarding the leakage
- Its accuracy rate is high
- There is no contact with the liquid
- The output is in analog form
- No moving parts in the ultrasonic flowmeter
- no loss of pressure
- it also conserves the energy
- it is suitable for hazardous liquids
- different models are also available, operated from battery
What are the limitations faced during the use of ultrasonic flowmeters?
Along with the advantages, there are some limitations you can face while using an ultrasonic flowmeter. They are below:
- It depends on the condition of the flowing liquid, like the length of the straight pipes.
- The requirement of pipe flowing should be full.
- Coatings are externally, or liners inside might cause problems in the functionality of the ultrasonic flowmeter
- Pipes with small diameter are not suitable for ultrasonic flowmeter
- Heavy flows affect the quality of the signal along with the readings
- Some applications whose velocity is low might not be appropriate for ultrasonic flowmeter
- it becomes sensitive along with the changes of the temperature
How to install the ultrasonic flowmeter?
To start ultrasonic flowmeter installation, you need to note the piping requirements. The place considered ideal is the section should be straight for the pipe and the distance of diameters of 10 pipes before and after the sensor 5 pipe diameters. Keep checking that the sound wave is easily transmitted even the liquid is dense.
If there is a clamp observed on the sensor, the signal must have strength in passing through the pipe of the wall. The ultrasonic flowmeter calibration is required at this stage by the manufacturers to meet the default conditions for the suitable medium. (Fuel. oil, gas, or water)
What is the working principle of an ultrasonic flowmeter?
The construction of the ultrasonic flowmeter is done through the transducers, placed upstream and downstream. It also has a sensor pipe and reflector. The working principle of an ultrasonic flowmeter is sound waves are being used to resolve the velocity of the pipe liquid.
The frequency increases along with the quicker flow of the liquid, which processes the signals from the transmitter, and you can receive the ultrasonic waves in multiple directions in the pipe. When there is no flow, the upstream and downstream time is the same as among the transducers. The rate of flow is decided through the transmitter, processed upstream and downstream.
Which industries use ultrasonic flowmeters?
The ultrasonic flowmeter is commonly used in oil and gas industries and used in different industries like chemical, beverages, food, metal, paper, food, and beverages, and water waste industries. The applications of dirty water also use ultrasonic flowmeters. You can monitor flowing water through an ultrasonic flowmeter.
It is a unique kind of flowmeter that measures the flow of liquids as well as gases. It is also helpful in generating power. Due to the features of ultrasonic flowmeter, its demand is increasing in the market of different countries. Food processing industries are also using ultrasonic flowmeters now.
What are the reasons for selecting an ultrasonic flowmeter?
There are two significant reasons for the selection of ultrasonic flowmeter are as follows:
- The installation process is easy: the most significant advantage of using an ultrasonic flowmeter is the ease of installation. According to the location, few sections need straight pipes, and for installation and maintenance for these processes no need to stop the whole system.
- Required maintenance is low: There is no blade for wearing out located in the turbine meters for replacement. Nor there are electrodes as it gets rotten in magnetic flowmeters. So, the cost is low in installation and maintenance processes.
How accurate is an ultrasonic flowmeter?
There is some uncertainty from 1% to 3% of the value measured for measuring the volumetric flow. It is dependent on the specification of the ultrasonic flowmeter. Some are very accurate, and the minimum rate to calculate the flow is 0.03 ft/second. You can find it sufficient for detecting the leakages.
There are no moving parts in the ultrasonic flowmeter, so the interference is minimum in the flow path. It results in delivering highly accurate data. Even on one pipe, you can install more than one ultrasonic flowmeter for receiving accurate measurements. The accuracy might get affected by the air which exists in the pipe.
What kind of liquids are measured by ultrasonic flowmeter?
The ultrasonic flowmeter measures a massive range of liquids includes:
- wastewater in the sewage
- corrosive liquids
- liquids abrasive along with the solids which are suspended in it
- water used for irrigation
- liquids related to petroleum
- sulfur in a molten state
- chemicals and liquids in cryogenic processes
- corrosive liquids
- water present on the surface
- portable water
There are some solid particles found in the slurry, might create a difference in the velocity measurement. You must be careful while using the ultrasonic flowmeter as the solid particles in slurry applications produce strong signals. It might also cause the ultrasonic flowmeter to measure the velocity of the particles, not the fluid’s velocity in the pipe.
How is velocity calculated on an ultrasonic flowmeter?
The ultrasonic flowmeter is a kind of flowmeter that measures the fluid velocity through ultrasound for calculating the volume of the flow. It is easy for the ultrasonic flowmeter to measure the velocity by the beam emitted by the ultrasound through the transducers. It is the average difference of the transit time measured through the pulses of the ultrasound.
It spreads along with the direction of the flow or through the frequency shift measurement by the Doppler effect. The transit times help calculate the total velocity of the fluid and the speed of the sound.
How is the working on ultrasonic clamp-on flowmeter?
The ultrasonic clamp-on flowmeter works on the principle of transit time. It means that the difference in the transit time is between the transmitter and receiver. The two sensors attached help in measuring this time. These sensors are fitted outside the pipe to receive the ultrasonic pulses through the wall of the pipe.
Sometimes, the liquid or gas flowing in the pipe can cause differences in time; deviations in the frequency and phase might get separated. These all factors are being evaluated by this type of ultrasonic flowmeter, and the received measurement is highly reliable. The actual concept is that the current flowing with the sound waves is faster.
What is the velocity range of is ultrasonic flowmeter?
Through an ultrasonic flowmeter, you can measure the rate of the flow. It is dependent on the measurements of the velocity published by the manufacturers. Ultrasonic flowmeter works on a particular range of velocity. It doesn’t depend on the temperature of the gas, pressure, or any kind of composition.
According to the mentioned guidelines, the limit of the velocity range is from 3ft/sec to 70 ft/second. The pressure range might affect the configuring of the meter as some different transducers do exist, which are specific to the pressure difference.
Does an ultrasonic flowmeter require calibration?
Ultrasonic flowmeter uses the principle of transit time where some type of calibration is required. Every meter has different calibration and during the shipment process before delivering to the customer. The new calibrated ultrasonic flowmeter measures the accuracy while comparing the flow rate provided as a reference to the flow rate present in the system. It is the rate where the single flow.
If the calibration is taking place properly, then the factors affecting the ultrasonic flowmeter are decreased. An individual ultrasonic flowmeter will work according to the specifications and standards mentioned.

- If the reading of the flow meter in the start and ultrasonic flowmeter shows the negative reading, It means the flow is running in the backward direction.
- If the output is not transmitting; then the connections need to be verified
What is the turndown ratio of an ultrasonic flowmeter?
The range of any instrument is called its turndown ratio. It is the ratio of measurement between the maximum and minimum capacity. Although there is no particular value of the flow, you can consider the application’s total. It will help you in determining the highest and lowest values of the flow.
If there is consistency in the flow value, it might not measure during the flowmeter selection. In calculating the flow, the turndown ratio indicates the flow range and how the ultrasonic flowmeter will measure the accuracy. The turndown ratio of the ultrasonic flowmeter is 250:1.
Units In measuring in ultrasonic flowmeter?
Flow is the volume of the liquid that passes in a particular unit of time. You can measure it in cubic feet per second in water resources, gallons per minute, cubic meters per second, or different units for the measurement. The measurement in ultrasonic flowmeter is a significant variety of applications, like controlling the system, designing and billing it. Under the steady conditions in which time is constant, the water flows from one corner to another. The equation made is that the velocity of the fluid flowing multiplied with the pipe area gives the flow measurement.
What is the response time of the ultrasonic flowmeter?
In an ultrasonic flowmeter, the transducers are in the clamp-on design. It helps detect the flow rate from the outer portion, and these are critical parts and never ignore this at any cost. You need to measure the response time Along with the accuracy rate of the ultrasonic flowmeter, which is also an essential factor.
The response is as fast as just one second. The users can also configure the response time range from 0 to 999 seconds. It has a significant impact on other features as well. It helps in making it more reliable for the applications.
How does an ultrasonic flowmeter handle the pressure drop?
The ultrasonic flowmeter is the perfect choice for the application wherever pressure drops or less maintenance is needed. It handles the pressure perfectly. The pressure changes help in determining the velocity of the flow. The flow rate is directly proportional to the pressure drop, which is between upstream and downstream.
There is no moving in the ultrasonic flowmeter and use in the applications of the industries. You can analyze the sensors of the pressure are increase around the walls of the ultrasonic flowmeter. It helps in performing and calculating the frequency and amplitude caused due to fluctuation.
What is the Doppler Effect in an ultrasonic flowmeter?
Doppler ultrasonic flowmeter works through the Doppler Effect. This flowmeter requires the air bubbles to operate. Two transducers found one is the emitter (the source of signal), and the other is the receiver. The transducer is the emitter, produce and forward the impulses of ultrasound. It is reflected from the bubbles and keeps changing the ultrasonic waves.
It depends on the velocity and signals are received again by the receiver. This device helps in determining the speed of the whole flow so you can analyze the entire process. The whole concept of the Doppler Effect is around the sound waves’ changes from the objects that are moving to the still position.
