2.2 Site Survey

Conduct a detailed survey of the installation site to ensure the following conditions are met:

  • Pipeline material: Ensure the pipeline material is suitable for ultrasonic sensors, such as metal or plastic.
  • Pipeline diameter: Confirm that the pipeline diameter matches the flow meter.
  • Straight pipe requirements: There should be sufficient straight pipe segments before and after the installation point, generally 10D upstream and 5D downstream (D being the pipe diameter), to ensure measurement accuracy.
  • Pipeline cleanliness: Clean the outer wall of the pipeline before installation to ensure it is free of dirt and rust.


3. Equipment Installation

3.1 Main Unit Installation

The main unit of the wall-mounted ultrasonic flow meter is generally installed on a wall or bracket near the sensors. The steps are as follows:

  • Determine main unit installation location: Choose a location that is easy to observe and operate, and not easily affected by the environment, such as avoiding direct sunlight and rain.
  • Install the bracket: Use an electric drill to drill holes in the wall and fix the mounting bracket.
  • Secure the main unit: Hang the main unit on the mounting bracket and secure it with screws to ensure it is firm and stable.

3.2 Sensor Installation

The installation position and method of the sensor significantly impact the measurement results. The installation steps are as follows:

  • Determine the installation location: Choose a suitable straight pipe section based on the site survey results.
  • Clean the pipe exterior: Use sandpaper or a wire brush to clean the pipe exterior, ensuring the surface is smooth and free of dirt.
  • Apply lubricant: Apply a suitable amount of lubricant to the bottom of the sensor and the contact surface of the pipe to enhance coupling between the sensor and the pipe.
  • Install the sensor: Fix the sensor on the pipe and secure it with insulating tape or waterproof tape, ensuring tight contact between the sensor and the pipe.
  • Calibrate the sensor: Adjust the sensor position according to the information displayed on the main unit until optimal signal strength is achieved.

4. Cable Connections

4.1 Power Connection

Ensure the power voltage matches the flow meter requirements, typically 220V AC or 24V DC. The connection steps are as follows:

  • Turn off the power: For safety, turn off the power before installation.
  • Connect the power cable: Connect one end of the power cable to the main unit’s power interface and the other end to the power outlet, ensuring it is securely fixed.
  • Check the connection: Confirm that the power cable is correctly connected to avoid loosening or short circuits.

4.2 Signal Cable Connection

The signal cable connects the main unit and the sensor to transmit measurement data. The connection steps are as follows:

  • Select the appropriate length of signal cable, avoiding excessive length or shortage.
  • Connect the cable: Connect one end of the signal cable to the sensor interface and the other end to the corresponding interface on the main unit, securing it with screws.
  • Check the connection: Ensure the cable connection is tight and free from looseness and damage.


5. System Commissioning

5.1 Initial Power-On

After installation, perform the initial power-on commissioning as follows:

  • Turn on the power: Switch on the power; the main unit display should light up normally.
  • Check the connections: Confirm that the main unit and sensor are correctly connected and the signal cable is in place.
  • Set parameters: Based on the pipeline conditions and measurement requirements, set the corresponding parameters on the main unit, such as pipe diameter and fluid type.
