Positive Displacement Flow Meters –
Accurate Measurement for High Pressure
and Wide Viscosity Applications

The positive displacement flow meter has a very high accuracy (±0.5%) and repeatability (±0.1%) and is considered one of the most durable and maintanance free type of meters. Most importantly it does not require straight pipe length for correct measurement.

Main Features:

• Suitable for low flow rates

• Measures flow for a wide viscosity range

• No need for straight run piping

• Bi-directional flow measurement

• 400:1 turndown ratio

• Available in high strength aluminum or stainless steel housing

 General Specifications:

• Accuracy: ±0.5% over the published flow range with fluids >100 cP; over a 10:1 turndown (from maximum flow) with fluids <30 cP

• Pressure Rating: 5,000 psi (345 bar) maximum

• Repeatability: ±0.1%

• Connections: Female NPT: 1/4 in., 3/4 in. or 1-1/4 in. (depending on meter size)

• Material of Construction: Stainless steel (gears and bearings)

• Housing: 6061-T6 aluminum or 303 stainless steel

• O-ring Teflon®, Viton® (optional)
