At Alicat, we offer a full range of flow instruments
Mass Flow Meters
Mass flow controllers provide precision measurement of gas flow, from 0.5 sccm to 12K SLPM. 3 sensor technologies make it easy to get what you need.
Mass Flow Controllers
Mass flow controllers provide precision measurement and control of gas flow, from 0.5 sccm to 12K SLPM.
Pressure
Pressure transducers or pressure controllers measure or control pressure in flowing, dead-ended or vacuum processes. Dual valve controllers and remote sensing options.
Custom Instrumentation
Flow and pressure instruments crafted to your specifications. Engineered to perform to your unique needs. Customize our products or get wholly new systems—like gas mixers, manifolds, or control loops.
Our devices are built on one of three core technologies to match your specific application:
Laminar Differential Pressure (DP)
M-Series and MC-Series
Ultra-fast response laminar differential pressure (DP) flow meters and controllers for gases and liquids, featuring low-pressure drop options for highly sensitive applications.
Coriolis
CODA-Series
Precision Coriolis mass flow meters and controllers deliver direct mass measurement for gases and liquids, fully fluid-independent with outstanding accuracy.
MEMs Thermal
BASIS-Series
Compact and efficient thermal mass flow meters and controllers, perfect for OEM integration and tight-space installations, providing reliable gas flow measurement.
Not sure what works best?
Your flow rate, pressure, and choice of gas can all affect which Alicat instruments work for your application.
Our Applications Engineers can answer your questions and help you find the best option.
We offer a wide range of solutions for mass flow and gas flow measurement, including thermal, Coriolis, and digital mass flow controllers and meters from brands like MKS, Bronkhorst, Aalborg, Sierra, and Omega. Our instruments support low flow, high-pressure, HVAC, hydrogen, oxygen, LP gas, and argon applications. We also provide analog and digital flow controllers, pressure regulators, fluid control valves, transducers, and transmitters. Services include calibration, recalibration, and flow meter verification. Whether you need inline flowmeters, bioreactor flow control, or medical air flow sensors — we deliver fast and reliable performance across industries.
