Positive Displacement Gas Flow Meter

Positive Displacement LPG meter（PD LPG meter） is a specific type of flow meter designed for measuring the flow of Liquefied Petroleum Gas, commonly known as LPG. LPG is a flammable hydrocarbon gas used for various applications such as cooking, heating, and fuel for vehicles.

PD LPG meters work on the principle of positive displacement, where the fluid is measured by dividing it into discrete volumes and counting these volumes as they pass through the meter. These meters typically consist of a chamber with a rotating mechanism, such as gears or lobes, that traps and moves a fixed volume of LPG with each revolution. The rotation of the mechanism is usually driven by the flow of LPG through the meter.

Advantage of Positive Displacement LPG meters

1.high accuracy and repeatability

2.suitable for precise measurement in LPG applications.

3.They are capable of measuring both high and low flow rates accurately

4. reliable performance across a wide range of flow conditions.

5. PD LPG meters are also known for their ability to handle viscous fluids and tolerate variations in temperature and pressure. Application: Refined petroleum products Liquefied petroleum gas(LPG); Crude oil, also for heated and/or viscous liquids;
