Alicat M Series mass flow meters monitor your mass and volumetric flow as well as your process pressure and temperature. This is all done simultaneously and every M series comes preloaded with 98 gases and gas mixtures, you can even add your own gas blends!
The mass flow meter is repeatable and accurate with calibrations up to +/- 0.4% of reading accuracy.
Every Alicat mass flow meter has a 10000:1 turndown ratio with full scale flow rates starting from 0.5 SCCM per minute up to 5000 SLPM.
The mass flow meter can be used as a standalone meter with the use of local display and push button keypad with a colour TFT display an option. The local display allows the user to see all flow data visible on one screen (mass flow, volumetric flow, absolute pressure, temperature).
RS-232 communications are standard as well as an analogue output signal such as 0-5 Vdc. Alicat M series can also be configured to support Industrial Protocols such as DeviceNet, EtherNet/IP, Modbus-TCP/IP and many others.
Every Alicat device is backed by the manufacturer's limited life time warranty and ships with a NIST traceable calibration certificate.
M series mass flow meters have a maximum operating pressure of 145 PSIG.
The data in the table below are standard configurations for models 10 SCCM full scale through 20 SLPM full scale. Please refer to the Mid-flow data sheet for full details.
| Mass Flow Accuracy at Calibration Conditions1 | ±0.6% of reading or ±0.1% of full scale, whichever is greater |
| High Accuracy Option1 | ±0.5% of reading or ±0.1% of full scale, whichever is greater |
| Bidirectional Option1 | No additional uncertainties |
| Repeatability (2σ) | ±(0.1% of reading + 0.02% of full scale) |
