Calibration of flow meters
Thread Content
The wedge flow meter belongs to the category of non-standard differential pressure flow meters; its discharge coefficient does not have a defined theoretical value. Unlike the discharge coefficient of orifice plates, which is a function of certain parameters, I would appreciate it if experts could advise me on how to carry out a simple or rough calibration for it after its geometric dimensions have been determined in practice
It is sufficient to correct the wedge flow meter in use by connecting a flow meter with a higher accuracy and known precision in series. Additionally, if it is a manufacturing plant, there are empirical formulas for calculating differential pressure and flow rate. How is it possible to produce a shaped product without any correction?
