Diesel Flow Meter

Additional Details

Positive displacement Flow Meters are precision made liquid measuring Flow Meters. These are available in single, double and triple capsule models to suit applications covering a wide range of flow capacities. Simplicity of design and construction ensures unmatched accuracy and trouble-free operation over long periods of use.
 
Design Features:
 
Low pressure drop
Unique wear compensating vane design for sustained accuracy over a wide flow range
Step-less calibration adjustment
Separate meter manifold prevents pipeline stresses from being transmitted to the measuring chamber.
Pressure balanced end covers protects distortion of measuring chamber due to line pressure.
Modular construction ensures interchangeable parts lower inventory of spares and ease of service.
Mechanical or electronic readout.
 

Principles of Operation:
The product enters the Flow Meter through the manifold inlet & causes the rotor to revolve by pressure on the vane blades. The proximity of the rotor to the body forms an efficient seal, whilst the profile of the body, ensures that the vane blades are guided through the measuring crescent. The vane blades divide the liquid into segments & each revolution of the rotor displaces for such segments.
 
Product at line pressure also fills the spaces between the inner & outer end covers so that the inner end covers which form the measuring chamber get ‘pressure balanced’ & are prevented from distortion due to line pressure.
 
The rotor spindle transmits the drive through a pressure tight lip seal in the meter front cover to the Calibrating Mechanism or the Pulse Transmitter which calibrates the meter output for a corrected counter readout. All mechanical Flow Meters are fitted with Veeder Root mechanical counters.
