Positive displacem... meter

Rotary / Positive Displacement (PD) Meter Skid. Gas and Liquid Measurement. Designed to measure the volume of a fluid passing through a rotary meter. Rotary meters have a small footprint and are best in low flow, small diameter applications making them perfect for start-up and stand-by situations.

Positive displacement flow meters measure the volumetric flow rate of a moving fluid or gas by way of precision-fitted gears or rotors containing cavities 

Positive displacement flow meters rely on moving parts to shuttle quantities of fluid through them, and these moving parts must effectively seal against each other to prevent leakage past the mechanism (which will result in the instrument indicating less fluid passing through than there actually is).

Positive displacement flowmeter In principle, positive displacement flowmeters requires no external energy such as electricity. The flowrate is calculated 

Positive displacement (PD) meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears.

The patented Flow Technology DC-I Series positive displacement flow meters (PD Meter) are ideal for a wide variety of liquid flow applications. These 

All PD meters require clean fluid so a filtration level of 100µm is usual. Some meters can actually block the flow if a larger particle is trapped in the wrong place. Many meters are not made in high specification materials and therefore corrosion can be a concern. An all plastic or all 316SS meter is the exception rather than the rule.

Aug 31,  · A positive displacement (PD) flow meter is a type of flow meter that provides high accuracy (±0.1% of actual flow rate in some cases) and good repeatability (as high as 0.05%

Positive Displacement flow meters are the only flow measuring technology to directly measure the volume of fluid that passes though the flow meter. It achieves this by trapping pockets of fluid between rotating components housed within a high precision chamber.

The Positive Displacement Meter is a volumetric flow metering device designed for the accurate measurement of petroleum and petrochemical liquids. The design provides the high accuracy

Most positive displacement meters are fitted with a totalizing dial, reading directly in liters or gallons. The readout mechanism often includes an adjusting device, so that if on calibration, the meter is found to be over-reading or under-reading, it can be reset to read correctly. If the meter is subject to legal control, this device will

Positive displacement flow meters are referred to as PD flow meters or PDF. They are the most accurate type in flow meters. Volumetric flow measurement uses a fixed small volume to repeatedly measure the volume of fluid passing through the flowmeter.

Positive displacement flow meter with flow range from 0.13-9.5 GPH through 40-660 GPM, measures viscous liquids. Starting at $602.00 AW Gear Meters JV-BB Series Flow Meter Positive displacement flow meter maintains consistent accuracy despite changing viscosity .

P.D. Meters. Positive Displacement is a very reliable flow meter type, which, in the rotary sliding vane design as the ISOIL one, offers the following advantages: High accuracy. Outstanding repeatability. Not sensitive to the flow profile and vibrations. Extremely robust. PD meters are VOLUME meters, i.e. volume is the primary and direct measure.

Positive Displacement Flow Meters. Brodie International offers a wide array of industry leading positive displacement measurement solutions. Our portfolio includes meters ranging from 1/2”

Positive displacement gas meters, also called PD gas meters, are among the most-used meters for utility billing applications as well as custody transfer of natural gas.

Positive-displacement meters, as their name implies, respond directly to movement of liquid and are capable of measuring flow rate to an accuracy better 

In fact, the defining characteristic of any positive displacement meter is that fluid or gas cannot move through it without affecting the mechanism, and that
