Mass Flow Meters
Alicat Scientific has been providing science and industry with precision instruments for measurement and control of gases and clean water since 1991.
A proprietary MEMs sensor enables each instrument to become four instruments: Mass Flow, Volumetric Flow, Pressure and Temperature with many related functions.
For example, a user can control on pressure while monitoring flow. The instrument is ready to use upon powering up — no warm-up time.
Unlike thermal based instruments, Alicat products can be used in any physical orientation, do not require straight piping run, and have a low sensitivity to ambient temperature and pressure changes.

M–Series Gas Mass flow Meters simultaneously measure mass flow, volumetric flow, gas pressure, and gas temperature for 98+ gases across a very wide flow range – 0.01% to 100% of full scale.
- Versatile & accurate. Real-time measurements with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
- Fast, multivariate data. Millisecond-response times immediately upon powering up, to display flow, pressure, and temperature readings in real-time, in your choice of engineering units.
- Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

MB–Series Portable Gas Mass Flow Meters measure mass flow and volumetric flow rates anywhere you need for 98+ gases, making them ideal for on-the-go process calibration, verification, and validation.
- Portable & durable. Built to be carried around, with a battery lifetime of up to 18 hours and drop-resistance.
- Versatile & accurate. Real-time measurements with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
- Fast, multivariate data. Millisecond-response times immediately upon powering up, to display flow, pressure, and temperature readings in real-time, in your choice of engineering units.
