What are the methods to check vortex flow transmitters flow reading is right?

There are numerous ways to verify the accuracy of a vortex flow transmitter’s flow reading. Listed below are a few popular techniques:

Simulate Flow:

Using a controlled flow of liquid or gas, you can simulate the flow to assess the vortex flow transmitter’s accuracy. The system’s maximum and minimum predicted flow rates should be represented by the simulated flow. To ensure accuracy, the output signal of the vortex flow transmitter can be compared to the simulated flow.

Compare readings with other meter :

Comparing the output of the vortex flow transmitter with another flow metre installed in the same system is an alternative method. Readings should be taken simultaneously at various flow rates from a second metre that could be of a different type, like an ultrasonic or magnetic flow metre. Any appreciable variations in the results could be a sign that the vortex flow transmitter is malfunctioning.

Verify against Calibration Certificate:

A calibration certificate describing the accuracy and calibration points of the vortex flow transmitter should be included. The device’s actual output can be compared to its predicted output using the calibration certificate. Any notable departures from the calibration certificate could be a clue that the vortex flow transmitter is malfunctioning.

Check for Damage or Build-Up:

It is crucial to look for any damage or build-up on the sensing components of the vortex flow transmitter. Any physical deterioration or accumulation can produce false readings. To ensure the accuracy of the transmitter, it should be frequently cleaned and inspected.

Overall, the vortex flow transmitter’s accuracy and dependability can be improved through routine calibration, inspection, and maintenance. It is advised to speak with a trained technician or flow measurement specialist if there are any doubts about the precision of the vortex flow transmitter’s results.
