Alicat Technology:

Alicat’s strength lies in the unique patented technology which makes us stand apart from the conventional competitors. Unlike traditional gas flow instruments which are based on the principle of thermal conductivity measurement, Alicat uses its unique combination of laminar flow channel and differential pressure measurement to give very precise and accurate readings for various gases.

Key Product Features:

Some of the Key Features of Alicat’s patented products are as given below:

  • Fastest Response Time – 10 ms (millisec) for Meters & 100 ms for Controllers, typically.
  • Gas SelectTM A unique Multi-Gas Calibration feature. This means there is no need to either calculate manually the mass flow rates or doing expensive recalibration for different gases.
  • No warm-up time.
  • Highest Turn Down Ratio (which defines the lowest possible gas flow measurement) of   200:1 in the segment meaning widest operating range practically possible.
  • No Mounting Attitude which mean they can be mounted in any orientation without compromising on performance
