Can a dual-flange differential transducer be used to measure the flow rate through an orifice plate?
As long as the range meets the requirements, it can be measured.
Double-flange transmitter connections are widely used in applications for measuring flow rate with orifice plates, especially in situations where the medium has special properties such as a tendency to crystallize when drawn out, tendency to settle, or corrosive characteristics.
The key is whether the interface is suitable; the pressure-taking interfaces for orifice plates are generally of the welding type, rather than the flange type.
For ranges of a few kPa to several dozen kPa, the accuracy of double-flange differential pressure transmitters is absolutely terrible. . . . . . How smelly is poop? Want to know? Below the Pagoda Hill, there is a dry toilet, and next to it is a place that sells fried stinky tofu – its smell is the most authentic. . . If the accuracy requirements for flow measurement are low, then go ahead and use double flanges. . . There was a talented person from Shanghai who would place his ear against the pipeline to listen; he could determine the flow rate with accuracy even greater than that of high-precision mass flow meters, helping his company save several tons of money :P
