M Series Mass Flow Meters
Mass Flow Meters with Laminar Differential Pressure Technology
Our most versatile mass flow meters because of the highly responsive, multivariate technology of Laminar DP. Great for versatility in research environments, with the precision and dependability for industrial applications.
- Laminar DP (differential pressure) mass flow measurement technology that Alicat pioneered
- 98 standard (up to 130) pre‑calibrated gas choices — switch without losing accuracy
- Measures mass flow, volumetric flow, temperature, and pressure
- As high as 0.01 – 100% measurement range (10,000:1 turndown)
- Limited Lifetime Warranty
0.5 SCCM – 12,000 SLPM
11.5 – 320 PSIA
M Series Meter
For most gas measurement
- 0.5 SCCM – 12,000 SLPM options
- 11.5 – 160 PSIA operating
- Accuracy as good as ± 0.5% of reading
- ± (0.1% of reading + 0.02% of full scale) repeatability
MQ Series Meter
Measure flow rates at higher pressures
- 10 SCCM – 12,000 SLPM options
- 11.5 – 320 PSIA operating
- Accuracy as good as ± 0.6% of reading or ±0.1% of full scale, whichever is greater
- ± 0.1% of full scale repeatability
MS Series Meter
For a wider range of gases
Corrosion-Resistant Wetted materials
- 130 gases, including corrosives
- 0.5 SCCM – 12,000 SLPM
- 11.5 – 160 PSIA
- ± 0.4% of reading and ± 0.2% of full scale accuracy
BIO Series Meter
Measure gases into and out of bioreactors + fermenters
-
Also uses laminar differential pressure mass flow meter technology
- Long-term stability
- Robust, compliant materials including USP Class VI or USPVI elastomers
- Designed for scalability (10,000:1 operating range)
