VPFlowScope M: insertion flow meter for compressed air and gases
4-in-1 insertion flow meter that simultaneously measures mass flow, pressure, temperature and totalized flow in a compressed air or technical gas network. It installs under pressure on an insertion valve, without a network shutdown, and replaces yearly recalibration with a simple on-site swap of the VPSensorCartridge. Standard or bi-directional cartridge (ring networks), in 220 or 350 mm; the transmitter connects over 4-20 mA, Modbus RTU or Ethernet (Modbus TCP).
From $4,062 CAD list prices, before taxes. Installation and shipping extra. Price subject to change without notice.

Frequently asked questions
- Does the VPFlowScope M need yearly recalibration?
- No. The VPSensorCartridge is swapped in minutes instead of being shipped out for recalibration; the device stays in service. Replacement cartridges are listed below.
- Can it be installed without stopping the compressor?
- Yes, on an insertion valve, under pressure, without a network shutdown. Our installation guide covers the measuring point, depth and wiring.
