Pressure Controllers

The CS Instruments VA 500 series of compressed air and gases sensor works on the calorific principle in a robust housing with and without local display.

The sensor is inserted into the flow path and can be done so even under pressure with the optional drilling jig.

VA 500 is mounted with a standard 1/2" ball valve allowing it to be installed or removed from the process with ease. A safety ring avoids an uncontrolled ejection of the probe which may be caused by the operating pressure.

Alicat Scientific’s mass flow meters provide precise measurement solutions for a wide range of gases and gas-based processes across numerous industries. Designed to automatically compensate for changes in pressure and temperature, they deliver both mass flow and volumetric flow readings—offering exceptional accuracy and adaptability for diverse applications.

Our selection includes models to suit almost any requirement. The standard M Series handles the majority of use cases, while specialised options are available for portable operation, corrosive gas handling, ultra-low pressure drop scenarios, and on-the-go calibration.

Each unit comes equipped with a clear local display and intuitive keypad for straightforward configuration, along with analogue output and RS-232 digital connectivity (additional communication protocols available). Every model supports measurement of over 80 gases and gas mixtures, with the flexibility to add custom gases. Users can also fine-tune readings by adjusting for fluid density, ensuring highly precise mass flow measurements every time.
