Optimising Water Distribution Networks and Groundwater Solutions

In water distribution involving networks, it is primarily pressure and flow measurement which is required. These measurements are necessary for accounting purposes, leakage detection and monitoring the pressure loss in the pipes. In large water distribution networks, further intermediate containers may be required in which depot chlorination is carried out. In this event, end control of the depot chlorination is initiated before the water is returned to the network.
The quality control cycle can be repeated with Liquisys M CLM 253 and
chlorine sensor CCS 140. A common transmitter concept ensures minimum
replacement part storage for all quality relevant online parameters. In order to monitor the network for pressure fluctuations, Endress+Hauser offers a pressure transmitter family with optimised segmentation to meet even the most demanding requirements.
The Cerabar pressure transmitter range from Endress & Hauser (GmbH) contains 3 types - the straightforward transducer (Cerabar T) with fixed measuring ranges, Cerabar M with complete communication capabilities and communication options (from 4...20mA to HART or PROFIBUS and the highly accurate Cerabar S with its modular design, which enables process connections, cell modules and electronics to be exchanged without requiring new calibration. Low, long-term drift (<0.1%/year or 0.25%/5 years) as well as function monitoring from the measurement cell right up to the electronics are further advantages of the Cerabar S in view of safety in the water distribution networks.
