Product Specification

VPFlowScope M Three-in-one Insertion Flow Meter Description
The VPFlowScope M is a three in one insertion flow meter for compressed air and technical gases. It can be installed under pressure and measures flow, pressure and temperature simultaneously. With the introduction of the VPFlowScope M, recalibration becomes history.

Unlike traditional flow meters, the VPFlowScope M does not require traditional recalibration, where you have to ship the unit back. Instead, the VPFlowScope M consists of a transmitter and the patented VPSensorCartridge® which reduces recalibration to a simple exchange.
