The flow output of the clamp-on vortex flowmeter is unstable

Project Overview

The clamp-on vortex flowmeter is based on the Karman vortex principle. When the flow output is unstable, troubleshooting can be carried out from the aspects of selection, installation and pipeline technology.

The main reasons for the unstable flow output are as follows:

1. There is a strong electrical interference signal, the instrument is not grounded, and the flow and interference signals are superimposed.

2. The straight pipe section is not enough or the inner diameter of the pipe is inconsistent with the inner diameter of the instrument.

3. The influence of pipeline vibration.

4. The flow meters are not installed concentrically.

5. The pipe is full of fluid.

6. The traffic is lower than the lower limit or exceeds the upper limit.

7. Cavitation exists in the fluid.

If the flow output is unstable, you can take the following measures:

1. Reconnect the shielding ground.

2. Replace the installation location.

3. Reinforce pipes to reduce vibration.

4. Reinstall the instrument.

5. Check the fluid flow conditions and the installation location of the instrument.

6. Increase or decrease the flow rate or adjust the filter parameters of the amplifier board.

7. Install a valve downstream of the instrument to increase the back pressure.

When the flow output of the clamp-on vortex flowmeter is unstable, you can refer to the above troubleshooting and processing methods. It should be noted that operations must be performed under the guidance of professional and technical personnel. Non-professionals must not operate blindly.
