MBQ–Series: Portable High-Pressure Gas Mass Flow Meters

Alicat MBQ-Series high-pressure portable gas mass flow meters are excellent instruments for convenient on-the-go process calibration, verification, and validation of processes with high operating pressures (up to 320 PSIA). Use this device to simultaneously measure mass flow, volumetric flow, gas pressure, and gas temperature of 98+ gases, anywhere you need it.

  • Portable & durable. These meters are made to be carried around, with a battery lifetime of up to 18 hours and the ability to withstand drops.
  • High-accuracy. Get real-time measurements of flows up to 320 PSIA with NIST-traceable accuracy to ±0.6% of reading or ±0.1% of full scale for 98+ gases, including custom mixtures defined using Alicat’s COMPOSER™ firmware.
  • Fast, multivariate data. Immediately upon powering up, the meter is ready to display instantaneous flow, pressure, and temperature readings in your choice of engineering units.
  • Easy integration. Custom process ports and electrical connectors in addition to your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications options enables easy integration into your industrial process.

Accessories included with purchase:

  • Micro-USB to USB cable for power and serial communication.
  • USB to wall adapter converter with four interchangeable prong configurations.
  • FlowVision software (free download)
