VP Instruments Air Compressor Monitoring Equipment

Flow meters for compressed air and industrial gases

We designed our flow meters to be easy to use, affordable and complete. You can use our flow meters for measurement of compressed air, nitrogen, oxygen, helium, argon and other industrial gases. The VPFlowScopes all measure 4 principles in one: flow, pressure, temperature and total flow. Moreover, all our flow meters can measure bi-directional flow, which is optional on our thermal mass flow meters with our proprietary Thermabridge sensors, and standard on our differential pressure flow meters.

VPFlowScope In-line 3/8″

Measure low flows of oxygen, compressed air and nitrogen. Up to 50 LPM

VP Instruments Air Compressor Monitoring Equipment VPFlowScope In-line 3:8

The VPFlowScope In-line 3/8” is the perfect solution to measure low flows of compressed air, oxygen or nitrogen. Getting insight leads to optimization of your air/gas system, reduction of consumption and you can allocate costs.

VPFlowScope In-line flow meter

The VPFlowScope In-line is the standard for point of use measurement of air and gas systems.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope in-line flow meter

With the VPFlowScope® In-line you have the perfect tool for measuring consumption of machines, cost allocation and pressure loss monitoring. The unique design makes this flow meter especially suited for smaller diameters. It is built for small pipes up to 2″.

VPFlowScope M flow meter

The VPFlowScope M is a four-in-one flow meter for compressed air and technical gases.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope M flow meter

The VPFlowScope® M is a four-in-one insertion flow meter for compressed air and technical gases. It can be installed under pressure and measures flow, pressure, temperature, and total flow 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.

VPFlowScope DP flow meter

The VPFlowScope DP is designed for wet and dirty compressed air flow measurement.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope DP flow meter

The patented VPFlowScope® DP is the ultimate measurement tool for saturated compressed air flow measurements. The unique design enables you to take measurements in the discharge pipe of a compressor under 100% saturated conditions. You can combine the probe with two display module types or with a connector cap without display.

VPFlowScope Probe flow meter

The VPFlowScope Probe measures mass flow, temperature and pressure simultaneously.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope probe flow meter

The VPFlowScope® Probe is the number one measurement tool for compressed air audits and fixed installations. You can combine the probe with two display module types or a connector cap without display. With the VPFlowScope Probe you can measure virtually any compressed air system using a single instrument .

VPFlowScope M Start Kit

The VPFlowScope M is a four-in-one insertion flow meter for compressed air and technical gases.

VP Instruments Air Compressor Monitoring Equipment VPFlowScope M start kit
