We have quite a few flowmeters a few of them have some issues but one of them is very critical.
The model is MVD 2700 Coriolis mass flow meter and it was giving inaccurate flow rates and very high totalizer quantities. This is known as there are pumps which are running at a certain RPM and giving approximate known fixed flow rates. Also, the quantity being pumped is known. So the totalizer should not go more than that and when there was no flow it still shows some flow readings. So, to resolve all these issues I tried to zero the flow and it didnt help much. Then i restored the factory calibration and it helped a bit, however, the erratic and heavily fluctuating flowrates exist and the totalizer also doesnt give the correct quantity.
Please can anyone provide more insight into this on what to do

Its a possible cause that foreign material might exist. I had purged a lot of water through the sensor in forward direction after installation. However, never tried flushing or purging in the reverse direction. Will try that one out pretty soon. No the piping supports are different and have adequate support and do not put extra stress on the flanges. Thats why i am very much surprised why its behaving erratic.
