Positive Displacement Flow Meters

9 products

Positive Displacement Flow Meters are important instruments for monitoring the flow of liquids in industrial, commercial, and laboratory applications. These meters offer reliable and accurate measurement of the flow rate of liquids, making them ideal for any situation where precise measurements are necessary. Omega Engineering offers a variety of positive displacement flow meters. Rugged and reliable, these meters are designed to work in a wide range of temperatures and pressures – providing a high level of repeatability and accuracy. These meters can also be used to monitor the flow of liquids in corrosive environments as well as liquids that have high viscosity.

Frequently Asked Questions

PD meters rely on tight mechanical tolerances. Changes in fluid viscosity affect "slippage" across the internal gears or pistons. Calibration ensures your meter remains accurate across your specific range of operating fluids and temperatures.

Over time, friction wears down internal rotors, increasing the gap between moving parts and the housing. Professional calibration detects this drift, ensuring you aren't under-reporting high-value fluids like fuels or oils.

Yes. We certify meters across diverse flow profiles. Our calibration verifies that the pulse or mechanical output remains linear, even when handling thick, non-Newtonian fluids common in Australian manufacturing.

Inaccurate dosing can ruin product batches or violate environmental discharge permits. Annual calibration is the only way to guarantee your volumetric delivery meets strict ISO quality and safety standards.

Yes. During the calibration process, we check for internal bypass leaks. This ensures the fluid is actually moving the mechanical elements rather than leaking through worn seals, which causes significant reading errors.

Due to high financial stakes and wear, annual calibration is standard. For high-volume fuel terminals or mining refueling bays, 6-monthly verification is recommended to maintain trade-level accuracy.
