Liquid Flowmeters

The Model F series of Flowmeters (operating on the Turbine principle), manufactured from precision-machined stainless steel, come with built in Totaliser / Flowrate Indicator Display, having both analogue and pulse outlet features as standard.

Operating Principle

F series Flowmeters basically comprise of three component assemblies, fitted inside a stainless steel body (locked with retaining rings), which has a magnetic pick up fitted.

The Rotor & Shaft assembly (1 off), which is mounted between journal bearings inside the Rotor Shaft Support assemblies (2 off), is turned by the kinematic energy of the flowing fluid at an angular velocity, which in the linear range of the Flowmeter, is proportional to the mean axial velocity of the fluid.

The Rotor blades sweep out the full bore of the meter except for a small tip clearance space. As the blade tips pass the magnetic pick up they initiate a pulse. Flow rate is determined by the frequency of the pulses and Totalised Flow is obtained by summing the pulses.
