We have acquired two pieces of mocromotion Coriolis flow meters model F200 and F300, both with 1700 transmitters from an auction in Europe.
We have mounted the F200/1700 vertically upwards on a 2” stainless steel pipe which is used to transfer fruit juice from one tank to another. While the batches of the juice are prepared carefully with precisely known weights, the flowmeter however is not reading correctly. For 5 test batches the deviation in weight were 4%, 1.3%, 4.84%, -2.99% and 7.77% respectively.
I have no idea if the flow meter needs any maintenance or calibration. I have to mention that the pump transferring the liquid juice through the flow meter is of piston type and some pulsating vibration is noticed in the piping and on the F200 itself.
I would appreciate if someone could enlighten me on how to solve the problem
