• Water treatment • pH must be constant • No tolerance to surfactants • Temperature 45 °C max. • Pressure 1 bar max.
Water treatment (for water equivalent to drinkable quality) at a constant pH.
Measured parameter: Free chlorine Chlorination additives: Inorganic compounds, such as NaOCl - Ca(OCl)₂ - gaseous chlorine, chlorine produced by electrolysis Caution: Surfactants not tolerated Output signal: 4 ... 20mA Operating temperature 1 to 45 °C Automatic temperature compensation Operating pressure 1 bar max. (No vibrations, no pulsating flow) Flow rate About 30 l/h pH operating range: Constant between 6 and 8 pH, pH value must be constant Interferences: Strong incidence of ClO₂ and O₃ on measuring signal; Chlorine produced by electrolysis with a non-diaphragm cell may cause damages. Zero adjustment: Not necessary (from factory) Slope calibration: Only 1 point with BAMOPHAR 194 according to directive DPD-1
