Analysis of bathing water circulation in public swimming pools

Non-invasive measuring



The German electronics specialists from Klingenberger GmbH undertake control cabinet construction and building control technology projects for public swimming pools and public buildings. In addition to production, installation and commissioning, their services include project planning for the conversion, renovation and new construction of fan and pump drives, planning of measurement and control technology to the integration of energy management systems.

For public swimming pools, DIN 19643 specifies circulation of the bathing water and the volume flows to be regulated in order to ensure the required hygiene standards. The speed of the pumps in these closed systems is set accordingly. The special feature of the partly patented energy-optimised control systems of Klingenberger for filters (EOFS) and pumps (EOPS) is the inclusion of reference variables that change based on pool conditions. Sensors record the water displacement by the current bathers per swimming pool. This variable data is measured in real-time so that, depending on the visitor load of a swimming pool, the necessary bathing water circulation per pool type, the required volume flows and energy feed for the installed pumps are automatically controlled. The purpose of these intelligent control systems is to reduce fresh water and energy consumption in order to optimise operations and reduce costs.

Non-invasive clamp-on ultrasonic flow measuring is a proven technique for reliably measuring volume flows in running processes. Because the measuring takes place from the outside, the cleanliness of pipelines is not affected. Katronic™’s clamp-on KATflow 200 can be quickly and easily deployed for system verification. Sensor attachment using clamping chains and clips is quick and easy. After entering a few measurement parameters, the portable flowmeter is immediately ready for use.
