What are the installation guidelines for the gas turbine flowmeter?
For installing the gas turbine flowmeter, you must follow some of the basic guidelines to receive the best results regarding the gas measurement. The reasons for providing the guidance are to improve the gas turbine flowmeter’s accuracy and increase the gas turbine flowmeter’s performance. Here, we are telling distance while handling the minimum requirements so you can double according to the conditions of the lengths of the straight pipes.
- Upstream: always permit the minimum length of the straight pipe ten times to the internal diameter of the pipe
- Downstream: always permit the minimum length of the straight pipe five times to the pipe’s internal diameter.
- Sometimes, the foreign materials present in the gas during the measurement causes clogging and impact the gas turbine flowmeter. So, to avoid this issue, it is better to install the screens for filtering out the impurities coming inside the gas turbine flowmeter.
- There are removable covering plates in the gas turbine flowmeter. Install the cover plates until the additional modules indicate removal. Never remove the cover plates whenever the gas turbine flowmeter is powered on because it can cause an explosion or electric shock.
- Never open the valve from shut to complete. All of the sudden flow can become the permanent reason for the damage of the rotor of the gas turbine flowmeter.
How does the gas turbine flowmeter work?
The speed of the rotor in the gas turbine flowmeter is directly proportional to the volumetric flow rate of the gas flowing through the blades. When the rotor starts turning, the reluctant coil mounted on the body of the gas turbine flowmeter knows the path of every tip of the blade and produces a sine wave output. The output from the pickup coil is the digital pulses that representation of the volume. It is a perfect match for electronic output devices, and there is no need for analog to digital conversion. The pickup coil works with instruments such as totalizers, flow computers, preamplifiers, and remote terminal units. The preamplifiers transmit the signals of the coil to the remote instruments, and you can install the gas turbine flowmeter directly to the turbine within the limit of the temperature. The gas turbine flowmeter is an available explosion, flame, and weatherproof approval.
How is the calibration and performance of the gas turbine flowmeter?
For determining the K-factor of the gas turbine flowmeter, water is used as the calibration medium. The gas turbine flowmeter works at various flow rates. This multipoint calibration is the verification of the linearity and repeatability over the particular range of the capacity of the gas turbine flowmeter. The derivation of the average K-factor in water is with the 1% deviation of one another. Therefore, water calibration is a valuable method for validating the gas turbine flowmeter.
Gas calibration also helps when:
- During the verification at the low-end capacity of the gas turbine flowmeter as per requirement for the implementation of electronic linearization.
- It is thoroughly testing the capacity at the upper end that is hard to perform on the water due to the pressure drop issues.
Must perform the gas calibration on the gas density, which is the same as the liquid density process. The linearity shows that no data point will extend the average of the data points within the linear capacity of the gas turbine flowmeter as per the standards. The installation with the straight pipe is important to get the particular linearity. You should install the gas turbine flowmeter and the upstream filtration to isolate the gas turbine flowmeter from the pollution and destruction from the solids or liquids.
How to install the gas turbine flowmeter?
The installation of the gas turbine flowmeter is directly inside the pipeline. To reduce the hurdles during the installation and receive the best results from the gas turbine flowmeter, installing the gas turbine flowmeter in the straight section of the pipe whose diameter should be a minimum of 10 pipes diameters from upstream and 5 pipes diameters from downstream. Install the control valves downstream of the gas turbine flowmeter. You can also install filters that can block the foreign particles that block the flow line. There can be the need for preamplifiers whenever there is a need for long transmission or noisy electrical surroundings near the motors, pumps, or generators.
What are the applications of gas turbine flowmeters?
Due to the features of the gas turbine flowmeter, the gas turbine flowmeter helps in settling the trade of crude oil and natural gas. In addition, the gas turbine flowmeter is helpful in the production processes to control the products as the provider of the signal feedback. The gas turbine flowmeter also serves as the controller of the controlling system. Due to the excellent reproductivity and repeatability of the gas turbine flowmeter, the gas turbine flowmeter is utilizing as the standard flowmeter for calibrating the device or periodically checking the typical table of the flow. The accuracy level of the gas turbine flowmeter is not less than 1.5. The petroleum industries, electrical power, and boilers use gas turbine flowmeters in their distribution network and natural gas transmission.
What are the troubleshooting issues in the gas turbine flowmeter and corresponding solutions to it?
|Reason for the cause
