VPFlowScope Probe: flow probe for audits and large pipes
Thermal mass insertion flow probe for dry compressed air: mass flow, pressure and temperature measured simultaneously. It installs under pressure on an insertion valve, without shutting the network down, and suits pipes over 2 in. Three readout versions: no display (connector cap, for a PLC or monitoring system), with display, or with display and built-in data logger, the reference version for compressed air audits, which logs on site with no computer.
From $4,543 CAD list prices, before taxes. Installation and shipping extra. Price subject to change without notice.

Frequently asked questions
- How is it different from the VPFlowScope M?
- Both are thermal insertion probes. The Probe is the audit tool, with optional display and built-in logger, rated up to 16 bar. The M adds totalized flow, an Ethernet output and the exchangeable VPSensorCartridge, built for permanent installation.
- Which probe length?
- The length follows the pipe diameter (400 mm or 600 mm in the catalogue; 300 mm on request). Onyx M3 confirms it at quoting for your piping.
- Can it log without a computer?
- Yes. The D11 version (display and built-in logger) records on site. D2 (no display) and D10 (display only) versions also exist.
