M Flow Meter

The VPFlowScope M is a flow meter designed for compressed air and technical gases that performs four measurements (pressure, temperature, flow, total flow) in one device.

It can be installed under pressure and simultaneously measures flow, pressure, temperature, and total flow.

The VPFlowScope M requires no calibration; its cartridge can be replaced without interrupting usage or sending the device for recalibration. In other words, unlike traditional flow meters, there is no need to return the device for recalibration. Thanks to its no calibration technology, you can change the cartridge in seconds and continue using it.

Instead, the device consists of two main components: a transmitter and the patented VPSensorCartridge®. This design allows the calibration process to be easily completed in the field by swapping the cartridge. Additionally, this method helps reduce your Scope 3 emissions.
