VPFlowScope M Thermal Mass Flow Meter

General

The VPFlowScope M Thermal Mass Flow Meter 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 Thermal Mass Flow Meter consists of a transmitter and the patented VPSensorCartridge® which reduces recalibration to a simple exchange.

Features and benefits

  • Four sensors in one instrument
  • For compressed air and technical gases
  • Patented VPSensorCartridge®: no more recalibration required
  • Ethernet interface: Industry 4.0/IOT ready
  • Ultra-compact size and low weight
  • Ethernet (Modbus/ TCP)
  • RS485 (Modbus RTU)
  • 4 … 20 mA linearized, pulse mode or alarm output
  • USB interface for configuration and downloading of data log files
  • Optional TFT color display
  • Optional data logger with up to 365 days @ 1 second interval + cyclic recording
  • Optional Wi-Fi interface (Web server for configuration, Modbus / TCP)
  • Optional: Bi-directional

Applications

  • Compressed air audits
  • Nitrogen and technical gas flow measurements
  • Cost allocation
