Positive Displacement Flow Meters - TL Series PD Flow Meters

We are Manufacturer, Supplier, Exporter, Services Provider of Positive Displacement Flow Meters - PD Flow Meters and our setup is situated in Pune, Maharashtra, India.

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.

Principle Of Operation

The product enters the Flow Meter through the manifold inlet and 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 and each revolution of the rotor displaces four such segments. Pressurised product also fills spaces between the inner and outer end covers, so that the inner end covers, which form the measuring chamber, are pressure balanced and are prevented from distortion due to line pressure. The rotor spindle transmits the drive through a pressure tight lip seal in the meter's front cover to the pulse transmitter or the calibrating mechanism to calibrate the meter output for a corrected counter readout. All mechanical PD Flow Meters are fitted with Veeder Root counter.
