Positive Displacement Flow Meters

R R Flowmeters offers Positive Displacement Flow Meters. The flow meters operate by repeatedly filling and emptying compartments of known volume with liquid or gas from a flow stream. The flow rate is calculated based on the number of times these compartments are filled and emptied. The main types of PD flow meters used for gas applications are diaphragm and rotary. These types of meters differ according to the way they trap the liquid into compartments with different shapes.
