Are standard orifice plate flowmeters the same for all manufacturers?

Project Overview

But only the orifice flowmeter can be called a standard part. This is determined by the structure of the orifice flowmeter.

The orifice flowmeter looks very simple, as if it is composed of two special flanges and two pressure pipes. Its various proportions are of unified specifications depending on the caliber size, and the materials are all stainless steel. Unlike other flow meters, different sizes can be customized according to the pipe length reserved on site.

So after basically establishing the three elements of flow conditions, the orifice flowmeters produced by the manufacturer are all standard parts. But they are not necessarily the same in other aspects. The orifice plate is just a sensor. What really measures and outputs the signal is the differential pressure transmitter. The differential pressure transmitters equipped by different manufacturers are different. Therefore, even if it is a standard orifice plate, the orifice flow meters produced by all manufacturers are not the same.
