Mass flow controllers

Specifically designed for original equipment manufacture and process integration, BASIS is Alicat’s smallest footprint instrument, providing fast, accurate control of gas flow rates in an economical, easy-to-integrate package. Ideal for use in OEM gas analysers, automated gas mixing on process lines, and anywhere basic mass flow-only control is required, the BASIS family now offers models with full scale at 100 cubic centimetres per minute, 1 litre, and 20 litres per minute.

Stocked and ready for quick ship on evaluation orders, all BASIS units are instantly on and performing at full accuracy in just 70 ms. A 100 ms control response enables BASIS to react in real time to upstream fluctuations. NIST-traceable accuracy is +/-(1.5% of the reading + 0.5% full- scale).

BASIS is available with the following multi-gas calibrations: Air, Ar, CO2, N2, O2, N2O (selectable over serial connection); He, H2 are also available in single-gas units. Multiple communications options – RS-485, RS-232 and Modbus Serial; and 0-5 Vdc analogue – mean BASIS can be built into a broad range of end-user products. For process applications, the availability of analogue and digital feedback allows for both PLC and PC control options.
