The mass flow meter exhibits large fluctuations
Thread Content
Our company has an E+H split-type mass flow meter with a diameter of DN25. Its measurement range is set at (0~800) kg/h, and it is used to measure the flow rate of tetrafluoroethylene gas. The gas pressure is between 5 and 8 kilograms, while the temperature is slightly lower than the ambient temperature. Since its installation, the flow rate has fluctuated greatly; moreover, there have been three instances of zero-point drift in the past two months. What could be the causes of this?
The person in charge of making the adjustments should give it a try; unstable intake pressure could also be the cause
Check for vibration and verify whether the installation is under stress
Send a picture to show how the installation is going; it will help everyone analyze the reason for you.
It also matters whether the pressure is stable.
I have uploaded the pressure and flow curves
It’s best to stabilize the pipeline pressure first, and then take a measurement
