Multipulse Medium Capacity Positive Displacement Flowmeters
PRINCIPLE OF OPERATION
The Liquid enters into a precision machined chamber which contains an oscillating piston. The positioning of the piston divides the chamber into compartments containing an exact volume. The liquid pressure causes the piston to oscillate and rotate its centre hub. The movements of the hub are sensed through the meter wall by a series of magnets. Each revolution of the piston hub is equivalent to a fixed volume of liquid, which is indicated as flow by an indicator or totaliser. Close clearances between the piston and the chamber ensure minimum slippage of the liquid for highly accurate and repeatable measurement of each volume cycle.
Trimec MP050 Series Positive Displacement Flowmeter measures low and high viscosity liquids up to 1,000,000 centipoise
