- positive displacement vane meter
Applications of positive displacement meters They are used in high viscous, dirty fluid which does not flow through the straight conduit. Hydraulic testing, Chemical injection or chemical dosing, pharmaceutical application and similar precision applications. Custody transfer of gasoline fuels. Overview of Positive Displacement Flow meters Jun 10, 2016 · Positive Displacement Meter is a type of flow meter that requires fluid to mechanically displace components in the meter in order for flow measurement. Positive displacement (PD) flow meters measure the volumetric flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes (finite increments or volumes of the fluid).
The positive displacement volumetric pump can pull and push product through a piping system. Recommended for loading and unloading, espe-cially for stripping tanks and piping of product. Positive Displacement Flow Meter PD Flow Meter Positive displacement type flowmeters usually offer high accuracy i.e. about ±0.1% of actual flow rate sometimes. The metering accuracy of the unit gets better with the increase in the process fluid viscosity. PD meters also provide excellent repeatability which can be as high as 0.05% of reading. PD meters can work without using a power supply. Positive Displacement Flow Meter SureM series meter is positive displacement meter for liquids. They are designed for liquid metering both in transfer and process control applications. Thanks to their design they are easy to keep and can suit a wide range of applications.
Rotary Vane Flow Meter (Positive Displacement Meter) LB series rotary vane flowmeter is a kind of positive displacement flowmeter, mainly used to measure the total flow of the liquid flowing through the closed pipeline, it has been widely used for the commercial and trade measurement to the raw oil, raw Positive Displacement Flowmeters for Viscous Media Positive displacement flowmeters measure the volumetric flow of fluids in pipes, such as water, hydrocarbons, cryogenic liquids, and chemicals. Some designs can measure gas flow although liquid flow applications are much more prevalent. In liquid service, increasing viscosity decreases slippage and increases the pressure drop across the flowmeter. Rotary Vane Flow Meter (Positive Displacement Meter)LB series rotary vane flowmeter is a kind of positive displacement flowmeter, mainly used to measure the total flow of the liquid flowing through the closed pipeline, it has been widely used for the commercial and trade measurement to the raw oil, raw oil finished products (petrol, kerosene, diesel etc.) and the chemicals, food etc.
The Coriolis flow meter and the weight method have a high degree of correlation and statistically are indistinguishable over the entire time and range of flow measured. On the other hand, the positive displacement meter, with a much wider precision range, does not conform as well to the weight method of flow measurement.Vane Brodie InternationalBrodie InternationalVane The Brodie Vane meter designed for oilfield waterflood applications is compact and reliable with only one moving part. The corrosion resistant materials of the case and internal construction were selected specifically for secondary recovery water service, or oil service.
