Answer / inst engnr

We can do dry calibration for a magnetic flow meter i.e. we have to remove the flow tube/ sensor connections from the meter and connect simulator to the transmitter. After the connections are given start simulation by adjusting knobs in the simulator, check the error. If there is any error we can do adjustment.

when the instrument tapping on pipe line is located below and transmitter is located above the tapping point for liquid service transmitter, what should we do, is there any additional drain valve is required??
