Positive Displacement Flow Meter

PD Meters are precision made liquid measuring instruments that maintain precise and accurate metering over long periods of operation. Positive displacement flow meter is known for its simplicity of design and construction, together with sustained accuracy. It is the only processes to measure fluid flow. These flow meters directly convert volume to rotational output with minimum scope for error and with minimal disturbance from surrounding conditions such as variations in temperature, pressure or viscosity.

Characteristics:
 

• PD Meters accuracy is 0.2%
• Positive displacement flow meter has sizes: 1.5", 2", 3", 4"
• They are used in LPG, Crude Oil, Chemical, Refined petroleum products
