Calculation of orifice plate flow meter range
Thread Content
There is an orifice plate flow meter on site; the original differential pressure transmitter gauge has been lost, so a new one has been installed. How should the range be set? The process requirement specifies a capacity of 0 to 15,000 kg/h. How can the differential pressure value of the differential pressure transmitter be calculated based on this specified range? Please, experts, help to answer! Thank you
Find the original orifice plate calculation sheet, or check whether the transmitter’s nameplate indicates the actual range (the range specified at the time of ordering).
It should be set according to the range specified in the orifice plate design manual....
According to the orifice plate calculation sheet, the full-scale differential pressure value is used to set the transmitter range via the handheld operator.

Second, since they can’t be found, we have to recalculate the costs using different methods; and to do that, we need to know the orifice ratio of the existing orifice plates.
