Positive Displacement Flow Meter

Exceptional Accuracy for Low Flow and High Viscosity Applications

Positive Displacement (PD) Flow Meters are ideal for measuring clean and viscous fluids with high precision, even at low flow rates. They function by trapping fluid in compartments and counting the number of revolutions to calculate the flow.

Commonly used in chemical dosing, fuel tracking, pharmaceutical batching, and lube oil dispensing, these meters offer high repeatability and are unaffected by changes in fluid viscosity, pressure, or temperature.

Installation Process

Follow these best practices to ensure a successful installation of your Positive Displacement (PD) flow meter.

Step 1: Choose Proper Location

Select a horizontal pipe section with stable flow. Avoid locations prone to air bubbles or vibration.

Step 2: Install with Full Pipe

Ensure the meter body is completely filled with fluid to prevent air pockets that can impact accuracy.

Step 3: Use Strainers or Filters

Install a strainer upstream to prevent damage from debris or large particulates in the flow stream.

Step 4: Align Flow Direction

Make sure the flow direction matches the arrow marked on the meter body. Reverse flow can cause inaccurate readings.

Step 5: Electrical Connections

For meters with digital transmitters or totalizers, wire according to the product manual and ensure proper grounding.

Step 6: Initial Calibration

Run fluid through the meter and verify calibration using a known reference to ensure optimal performance.

Frequently Asked Questions

A positive displacement (PD) flow meter directly measures fluid volume by trapping fixed amounts of liquid and counting the number of times the chamber fills and empties.
PD meters are ideal for highly viscous liquids like oil, grease, fuel, resin, and syrups used in chemical, food, and oil industries.
No. Basic PD meters are mechanical and do not require power. However, advanced models with digital displays or transmitters may need external power.
Yes. Most PD meters should be installed horizontally, fully filled with fluid, and free from entrained air to ensure accurate readings.
They offer excellent accuracy, typically ±0.2% to ±0.5% of reading, especially for high-viscosity fluids.
