Does a newly purchased electromagnetic flowmeter need to be calibrated?

Does a newly purchased electromagnetic flowmeter need to be calibrated? Dielectric saline solution. When reviewing information on orifice plate flowmeters, it was stated that \"orifice plate flowmeters manufactured and installed in accordance with standards can perform flow measurement within a known range of uncertainty without the need for calibration.\" ”, rather than standard differential pressure flowmeters (Anubas, V-cone, etc.), it must be obtained through actual flow calibration (so-called actual flow calibration generally means that, in the absence of explicit standards, the medium being measured and the test medium should be the same; in other words, instruments used to measure steam should be calibrated using steam). So, I would like to ask whether it is necessary to calibrate a newly purchased electromagnetic flowmeter
For process control only; no calibration required
Generally, manufacturers carry out actual flow calibration before shipping the products; it’s not clear whether this requirement applies when placing an order. If it isn’t specified, one can ask the manufacturer whether such calibration has already been done. For flow meters used for control purposes, the manufacturer’s calibration results can be used directly.
We usually use water marks to indicate it, and find a container to measure the amount of water.
If trade settlement is required, then the measurement department needs to carry out calibration; otherwise it’s unnecessary, and generally there are no suitable equipment available for such calibration
:handshake thank you
Well, this works too, but it’s probably only suitable when high precision isn’t required, right?
