In-line Multi-parameter Water Sensor Chlorine, Conductivity, Pressure, Temperature KAPTA 3000-AC4 In-line Multi-parameter Water Sensor General Description The KAPTA 3000-AC4 probe has been specifically developed to enhance the management and control of the drinking water distribution network. The KAPTA 3000-AC4 monitors the important water parameters chlorine, conductivity, pressure and temperature using innovative, integrated technologies. The chlorine is measured using a three electrode amperometric sensor designed to monitor the active chlorine (HOCl). The pressure sensor uses a silicium piezoresistive cell and the conductivity is a measurement using four electrodes. These integrated sensors require no maintenance or recalibration and allow for the online monitoring of the drinking water distribution network systems. The KAPTA 3000-AC4 continuously measures and stores the 24 last measurements based on the chosen data acquisition mode. The communication module (IP68) queries the probe to allow real time telemetry data transmission to a central server. All the data measured by the probe is organized into an easy to use interface for the operator. The design of the KAPTA 3000-AC4 probe and its use and mode of communication have been designed to facilitate its implementation and application on site. This innovative, modern and reliable monitoring solution provides real-time control of the distributed water quality. KAPTA 3000-AC4 In-line Multi-parameter Water Sensor Benefits * Real time water network monitoring * In-line water contaminant identification * Efficient control of water distribution KAPTA 3000-AC4 In-line Multi-parameter Water Sensor Main features * Measurement of the main disinfection species * No interference with chloramines * Chemical free operation * Annual maintenance and calibration * Easy field installation with direct insertion in pipe, under pressure, using standard collar and valve * Battery operated * Real time telemetry data transmission to a central server KAPTA 3000-AC4 In-line Multi-parameter Water Sensor Applications: Drinking Water Security * Real-time, in-line monitoring of key parameters in the water distribution system * Detection of any changes in your water quality commonly caused by leaks, pipe corrosion and biofouling effects, etc. * Disinfection process optimization
