PRINCIPLES OF OPERATION
The product enters the Meter through the manifold inlet & causes the rotor to revolve by pressure on the blades. The proximity of the rotor to the casing forms an efficient seal, whilst the profile of the casing ensures that the blades are guided through the measuring crescent. The blades divide the liquid into segments, the liquid segments are counted as they are displaced, giving a positive rotary motion to the rotor. The rotor spindle transmits the drive through a pressure tight lip seal in the Meter front cover, to the Calibrating Mechanism which calibrates the Meter output for a correct Counter readout.
