Total Chlorine Sensor GCM

The total chlorine sensor GCM serves to determine the total chlorine concentration of potable water, pool water or water of comparable quality. The sensor is mounted to the sampling station DCM 01.

The TOPAX NT serves as measuring and control unit. Only by using the sampling station DCM 01 the desired inflow parameters are achieved which are necessary for a safe operation of the sensor. Air bubbles in the sample water may cause false measuring results and have to be avoided. The sampling station DCM 01 must be operated in a pressureless condition. For monitoring the flow a flowmeter is provided which opens a contact when no flow is present. This contact sets the control of the connected TOPAX NT to 0 % thus avoiding undefined metering. The total chlorine sensor has to be serviced and checked for impurities, plant contamination and air bubbles regularly. Impurities can be removed by means of a water jet.
