VPInstruments compressed air flow meters
The complete VPFlowScope range: in-line flow meter for the point of use, insertion probes installed under pressure for main headers, and a differential pressure probe for hot, saturated air at the compressor outlet. It is the measurement technology behind our audits. Distributed by Onyx M3 Inc.: list prices, quote by cart.
Not sure which model?
The selector follows the VPInstruments decision tree: air quality, pipe diameter, pressure, then readout, communication and power. It builds a list of real parts with their prices, added to your quote in one click.

The right flow meter in three questions
- Is the air wet (before the dryer)? Yes: VPFlowScope DP, differential pressure, built for hot, saturated air.
- The air is dry: is the pipe 2 in or smaller? Yes: VPFlowScope In-line, mounted in the piping, for consumption per machine or workstation.
- Pipe over 2 in: what pressure? Below 10 bar (145 psi): VPFlowScope M, with exchangeable cartridge. From 10 to 16 bar (145 to 250 psi): VPFlowScope Probe.
Based on the VPInstruments VPFlowScope selection tool. Onyx M3 validates the measuring point before ordering.
