Mass flow controllers

22 September 2016

Alicat Scientific has expanded its BASIS line of mass flow controllers, adding a new 20SLPM model to fit a wider range of applications including sparging into liquids, sample dilution, and many gas mixing applications.

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. Suitable 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 70ms. A 100ms 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.
