Optimizing Water Distribution Networks and Groundwater Solutions
Optimizing Water Distribution Networks 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 optimized segmentation to meet even the most demanding requirements. The Cerabar pressure transmitter range 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. Groundwater The operation of wells requires the measurement of level, pressure and flow. In order to measure the level in wells, rope probes are fitted in stilling well with very small diameters. Endress+Hauser‘s hydrostatic level probe Waterpilot FMX 167 has been specially developed with an external diameter of 22mm. It is perfect for this application and can be directly installed in the stilling well. Reliable measurement is thereby ensured to control water extraction from the well network. Hydrostatic level measurement, combined with flow and pressure measurement, is used to determine the mechanical pump performance. By employing the electrical pump performance as a measuring parameter, the degree of efficiency can be calculated. Endress+Hauser‘s Memo-Graph multi-channel paperless recorder with datalogger is the ideal solution to register the required parameters and perform calculations. The Memo-Graph multi-channel paperless recorder with datalogger is certified tamper-proof and features mathematical functions. Quality control is essential where there is a danger of pollutants entering the source water. Turbidity measurement provides the ideal solution. In the event of rainfall, it is recommended that the well be closed as soon as 0.3 turbidity units are reached. This is done in order to avoid excessive treatment costs due to polluted raw water. Nitrate measurement can also be an important monitoring parameter in the well if agricultural activity is found in the vicinity of the well. Diffusion of nutrients makes inline nitrate measurement an additional safety factor for the well operator.
