A range of Incremental Encoders has been developed to enable water level measurement to a 1mm accuracy over a range of 10 metres or more.

All of these Encoders have been designed with power efficiency in mind and can be operated using pulsed power supplies to extend battery life.

The encoders have been successfully used by the Environment Agency, SEPA, Natural Resources Wales, among others.


The most popular variants are:

24R-105 Encoder, 100ppr, Cable exit, Anodised Aluminium housing

24R-120 Encoder 100ppr, RMD connector, Anodised Aluminium

24R-121 Encoder 200ppr, Cable exit, Anodised Aluminium housing

24R-140 Encoder 200ppr, Cable exit, Anodised Aluminium housing
               Square mounting flange

Variants for all the encoder ranges are available. Please contact us with your specific requirements.


All of the above are suitable for use with RMD Series Water Level Indicators.

Alternatively they may be interfaced with industry standard telemetry and/or datalogging equipment.
