In-line Flow Meter

The VPFlowScope® In-line is an ideal flow meter used for point-of-use measurements of compressed air and industrial gases such as nitrogen, oxygen, carbon dioxide (CO₂), helium, and argon. Operating with thermal mass flow sensor technology, this device simultaneously measures bidirectional instantaneous flow, pressure, temperature, and total flow.

Specifically designed for small diameter pipelines, the VPFlowScope In-line provides all the data needed to optimize compressed air systems in a single sensor. It is available in two pressure range options: 16 bar and 35 bar.

Model options include:
• Basic model without a display, suitable for simpler applications.
• The most advanced model, equipped with an integrated display and a data logger with a capacity of 2 million points.
The VPFlowScope In-line is suitable for a wide range of applications, from standalone use scenarios to integration with energy monitoring systems like VPVision or your facility’s own SCADA system.
