What causes mass flow meters to fluctuate?
The exclusion of external factors, if the fluctuation of technology still can not accept, you can increase the damping time, the damping time, with this data refresh almost, if the refresh too fast it is easy to cause excessive fluctuations in time and frequency is inversely proportional to the time of design, the frequency becomes small.
Check the sensor K1, K2, K3, FD coefficients are consistent with the nameplate parameters (see step reference fault 2), found inconsistent, may be the core processor is replaced, retrieve the original processor installed on it. When the replacement of transmitter to power under the condition of fixed screw loose core processor module of the central government, gently pull out from the housing to the core processor, and vertical carefully removed from the sensor core processor. Do not rotate or turn the core processor to avoid pin bending or damage. The density parameter fluctuates greatly to see whether the drive gain is more than 20%, whether the sensor has gas-liquid two-phase mixing, and then can solve the wave problem by allowing the sensor to be full.
The flow of the flowmeter is normal, which is related to many factors,For example, whether the pressure in the pipeline is even, whether there is interference or not
1. There may be a vibration disturbance near you2, it may be that the flowmeter has pulsating flow3, the installation of a problem4, the instrument itself quality is not pass, signal processing technology does not pass
