Clamp on type ultrasonic flow meter installation method

 

The installation method of clamp-on ultrasonic water flow meter can be carried out according to the following steps to ensure that the installation process is clear and accurate:

 

1. Preliminary preparation

 

Check parameters:

Check the parameters of the installed pipe, such as pipe diameter, wall thickness, etc., to ensure that they match the requirements of the flow meter.

Use a tape measure to measure the circumference of the measured pipe and calculate the pipe diameter accordingly.

 

Select installation method:

According to the pipe diameter and actual conditions, select a suitable installation method, such as V method or Z method.

V method installation: Applicable to pipe diameters of DN15mm-DN400mm. During installation, the two sensors are horizontally aligned, and the center line is horizontal with the pipe axis.

Z method installation: Applicable to pipes with a diameter greater than DN100, especially when the pipe is thicker or there are suspended matter in the liquid. When the Z method is installed, the ultrasonic wave is directly transmitted in the pipe, and the signal attenuation is small.

2. Installation steps

 

Wiring:

 

Host part wiring:

 

Power supply wiring: According to the wiring diagram, select AC 220V or DC 24V power supply for wiring.

Sensor wiring: According to the wiring diagram provided by the manufacturer, connect the downstream probe and the upstream probe to the corresponding wiring terminals respectively.

Other wiring: such as 4-20mA current output, 485 communication, heat meter, relay switch quantity, etc., connect according to specific needs.

Probe part wiring: Usually only the +- terminals need to be connected, and the shielding wire is usually not connected.

 

Install the sensor:

 

Select the installation location: Make sure that the installation location is full of pipes and stable flow, away from pumps and elbows.

Polish the pipe: Use an angle grinder or coarse sandpaper to polish the area where the sensor is to be installed, remove rust, paint or anti-rust layer, and expose the metal nature of the pipe.

Apply coupling agent: Apply enough coupling agent on the sensor.

Install the sensor: Press the sensor against the pipe wall and fix it with a clamp (such as a stainless steel belt) to ensure uniform force. Note that there should be no air bubbles, gravel or other dirt between the sensor and the pipe wall.

 

Determine the installation distance:

 

According to the parameters set in the host menu, check the sensor installation distance and install the sensor according to this distance.

 

3. Debugging and inspection

 

Confirm the pipeline status:

Confirm that the liquid in the pipeline is full and check whether the pipeline status is normal.

Check the signal:

Enter the relevant window to check the transmission time ratio and ensure that it is within the normal range (such as 100%±3%).

Check the Q value of the upstream and downstream signal strength and signal quality to ensure that the signal strength and Q value meet the requirements (such as signal strength above 60 and Q value above 75).

 

Debug:

Perform necessary debugging according to the actual situation to ensure that the flow meter can work normally.
