VPFlowScope M Thermal Mass Flow Meter

VPFlowScope-M Insertion Thermal Mass Flow MeterThe VPFlowScope® M is a four-in-one flow meter for compressed air and technical gases. It measures bi-directional flow, pressure, temperature and totalized flow, simultaneously. 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.

Features and benefits
