The 97R Digital Flowrate Indicator has been designed for use with turbine or pelton wheel flowmeters having a low level signal output sinusoidal or square wave. The four digit LED display can be scaled to read in any desired flow units, e.g. litres per minute, cubic metres per hour, etc.

The controls for factorising, decimal point selection etc, are located at the front of the instrument, but hidden behind the front panel, thus preventing unauthorised tampering. An additional facility available within the unit is dual input operation, whereby the signal from 2 flowmeters may be compared, and the ratio of frequencies displayed.
