Device for online water hardness monitoring for quality controlled triggering of regeneration

Various operating modes allow both, a pure water hardness monitoring as well as a quality controlled triggering of regeneration of the water softener. Compared to a quantity controlled operation, the soft water throughput will be substantially increased and operating costs reduced.


Dimension of case/Weight: 400 x 250 x 160 mm (W x H x T) / approx. 8 kg

Surrounding temperature/Relative humidity: 5°C ... 50°C / 20% ... 80%

Power supply: power supply unit 100 … 240 V / 50 … 60 Hz

Power consumption: 15 V DC, approx. 20 W

Raw and soft water connection: branch pipe with connection for PA-hose o.d. 4 mm, i.d. 2 mm, up streamed dirt filter ≤ 0.1 mm recommended

Raw and soft water pressure: minimum 3 bar up to maximum 10 bars

Drain: minimum ø 15 mm, pressure free

Quality of raw and soft water: natural water, free of grease, oil or brine germ content < 5000 CFU/ml

Hardness range raw water: 1° dH ... 60 °dH (adequate in mmol/l, °f or ppm)

Hardness range soft water: 0.01 °dH ... 1.0 °dH (adequate in mmol/l, °f or ppm)

Threshold value calibration: 0.05 °dH ... 1.0 °dH (adequate in mmol/l, °f or ppm)

External signalling: potential free contacts (threshold value or sensor alarm) current loop 4...20 mA (4 mA = 0.05°dH, 20 mA = 0.5°dH)

Measurement cycle process controlled: contact water meter or external opener/closer

Connection control of softener: triggering of regeneration via potential free contact

Self monitoring: automatically

Operation time of sensor: approx. 6 ... 9 months (without warranty)
