Flowmeters handle higher flows

Controlling higher gas flows has always been difficult, leading to many "Heath Robinson" assemblies of flow sensors, control circuits and automatic control valves.

Controlling higher gas flows has always been difficult, leading to many "Heath Robinson" assemblies of flow sensors, control circuits and automatic control valves.

As part of its digital product development, Teledyne Hastings Instruments has applied lessons learned in its R and D programme to control higher flows using the output from its inherently linear mass flowmeters.

Flow ranges up to 10,000 litre/min (standard) may be specified using either analogue or digital control, the digital instrument having RS232 or RS485 interfaces in addition to the standard 0-5V or 4-20mA analogue signals.

Analogue or digital versions provide precise measurement and control in a compact, economical package.

Full support is available from Hasting's European Service Centre operated by Chell Instruments, whose UKAS calibration laboratory has the lowest uncertainties for gas flow outside National Standards.
