A Guide to Sizing Orifice Plate Flow Meters The Orifice Plate is a very robust flow measurement device. It is one device that is very easy to use and can easily be adaptable to many flow measurement applications. Its cost of operation is minimal and familiarity with the device is near universal. All these pluses make the Orifice Plate the first choice measurement device in almost every flow application. It does however have some limitations which makes the Sizing process a little tricky. Two key limitations include: (a) Limited Turn Down (b) Non-linear loss of accuracy at low flow rates as shown by the graph below: As can be observed from the above graph, large errors are introduced into the measurement system by Orifice plates at low flow rates.
