A next-generation 4-in-1 insertion flow meter for compressed air and technical gases, featuring the patented VPSensorCartridge® for field-swappable on-site recalibration with zero downtime. Measures flow, pressure, temperature, and total flow simultaneously. Available in two cartridge sizes covering pipe diameters from 1" to 20". Industry 4.0 ready with built-in Ethernet.
The next step in flow measurement
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 in the field and lowers your scope 3 emissions as well.
Industry 4.0 ready
With its standard internal Ethernet interface, the VPFlowScope M will connect directly to any network and will form seamlessly one of the cornerstones of any real-time energy management platform. But it is also compatible with the traditional world, thanks to the standard 4..20 mA signals and RS485 (Modbus RTU) interface.
One Transmitter. Many possibilities!
Thanks to the versatile IO, the VPFlowScope M Transmitter can be connected to both the traditional 4..20 mA, RS485 (Modbus RTU), and modern Ethernet based systems. The Transmitter is available in three versions.
No more recalibration
With the patented VPSensorCartridge®, traditional recalibration is something of the past. From now on, you simply exchange the VPSensorCartridge® and continue your measurements. No more waiting, no more downtime.
