Water abstraction

APPLICATION REPORT Water & Wastewater Flow measurement in the abstraction of drinking water from dunes • Environmentally friendly alternative for the abstraction of water without chemicals • Burial installation with short-term flooding, maintenance-free measurement • Reliable and accurate drinking water flow measurement for monitoring purposes 1. Background Water utility company dunea supplies approx. 1.2 million Dutch residents with high quality drinking water. Dune passage is a natural treatment method that forms an environmentally friendly alternative to the purification of water with chemicals....

APPLICATION REPORT Process of natural purification of drinking water ( 1 Water pumped from dunes, 2 Flowmeter, 3 Water softening, 4 Carbon dosage, 5 Cascades, 6 Filters, 7 Slow filters, 8 Clean water basements, 9 Water tower, 10 Supply line to consumers 3. KROHNE solution KROHNE supplied the OPTIFLUX 2300 F electromagnetic flowmeter for this application. F stands for remote version, i.e. sensors and converters are connected to one another via signal and field current lines. The stainless steel housing for the sensor is in protection category IP68. The fully welded construction is 100% water tight...

APPLICATION REPORT Water & Wastewater Maintenance and regeneration of water wells • Accurate flow measurement for water well testing and inspection • Battery powered measurement solution for remote locations • Water meter with high turndown ratio for varying flow rates 1. Background Q-FLOW International, founded in 2002, is an independent well regeneration and maintenance company. It builds new wells, performs camera inspections and maintains existing water wells and water treatment installations. The maintenance of wells involves for example the exchange of pumps and pipes, the cleaning of filters...

APPLICATION REPORT Maintenance skid with WATERFLUX 3070 for well maintenance 3. KROHNE solution Q-FLOW decided to equip its maintenance skids with the WATERFLUX 3070 water meter. The battery powered electromagnetic flowmeter is designed for water abstraction applications. Its measuring tube with a rectangular and reduced cross-section enables a stable measurement even at low flow rates. Due to its optimized flow profile, the WATERFLUX 3070 can be installed in the confined space of a maintenance skid without straight inlet or outlet runs. At locations, where the piping cannot be removed or where there...

APPLICATION REPORT Water & Wastewater Measurement solution for monitoring water abstraction wells • Energy self-sufficient flow and pressure measurement for long-term well monitoring • Combined solution for efficient groundwater management 1. Background The water utility company Leipziger Wasserwerke operates four large water plants in Germany that supply about 75 percent of the drinking water for the city of Leipzig and its surrounding area. Two of these water plants mainly abstract raw water from the bank filtrate of an adjacent river. 2. Measurement requirements Depending on their location and...

APPLICATION REPORT 3. KROHNE solution KROHNE recommended the use of a combined solution made up of the WATERFLUX 3070 C water meter, the OPTIBAR LC 1010 C submersible level probe, the OPTIBAR P 1010 C pressure transmitter and the GSM/GPRS data logger KGA 42. The battery-powered WATERFLUX 3070 water meter is perfectly designed to measure in confined well shafts without inlet and outlet run. As the wells may be flooded, the IP68 rated version of the water meter has been supplied. It continuously measures the flow volume and transmits the data via its pulse output, either once every hour or once every...

APPLICATION REPORT Water & Wastewater Remote monitoring of groundwater abstraction points in city of Jakarta • Test and evaluation of a one-stop-solution for water metering, wireless transmission and remote monitoring of readings • Retrofitting of mechanical water meters to charge customers for abstracted water from wells • Comparison of operability and data security of two remote monitoring systems 1. Background It is quite common in emerging countries that major water consumers like residential parks, hospitals, hotels, industrial companies, golf clubs or shopping malls abstract their raw water...

APPLICATION REPORT As part of the project, a PC- or Web-based solution for remote monitoring of the readings was also asked for. Emphasis was put on the security of remote transmission as well as a clear and user-friendly analysis and visualisation of values at customers’ control room. 3. KROHNE solution KROHNE was the only supplier to match the given requirements and was choosen for the first field test in 2010. KROHNE delivered a one-stop-solution of stand-alone water meters with wireless data transmission together with remote monitoring system. Field and office personnel were trained on-site...
