Troubleshooting of E+H mass flow meters

I think there’s definitely a problem with the zero calibration; do I need to input an additional value or use some other method?

There are many reasons for this: whether there is a vibration source when the valve opens, whether there is an electromagnetic environment in the vicinity, and so on

1. The issue of verticality: the flow meter may tilt to one side. 2. If not tightened properly, oscillation may occur.

When the air traffic control detection is turned off or on, is it in an air traffic control state or a non-air traffic control state? If so, it means there is indeed a small flow rate; when it is turned on, the alarm displays 0 directly. .

I encountered the same issue on site: when the air traffic control detection function was turned off, it wouldn’t return to zero. The manufacturer came and said it was caused by an issue with the sensor. However, it is said that there is data transfer even when there are vibrations, but this seems to have nothing to do with setting the air traffic control system to zero.

First, I would like to know whether the E+H mass flow meter can operate properly when air management detection is enabled If possible, just keep it running without worrying about it. A mass flow meter will exhibit a non-zero flow rate when the pipe is not full; this is determined by the principle of the flow meter itself and cannot be eliminated by the flow meter. If, when there is traffic, you observe that the density differs from the expected density, then it’s definitely a problem with saturation. So, I suggest that if leaving the air traffic control detection on allows normal operation, keep it on. Otherwise, modifications must be made to the piping design, such as installing it on vertical pipe sections. P.S. I have not used an E+H mass flow meter; I have only analyzed it based on its principles. Please point out any errors if there are any. Thank you.
