Measuring instrumentation

The correct management of the water system at the base of the swimming pool system involves monitoring the volumes. In the case of volumes conveyed inside pipes we will monitor the flow rate, in the case of the volume accumulated in the compensation tank we will measure the level value.

The recirculation system must be designed to ensure effective homogenization of the tank water, for this reason UNI 10637:2016 prescribes adhering to a speed of water in the pipe <1.7m/s in suction and <2.5 m/s in sent; while UNI EN 10713-2 prescribes a speed <3m/s for type D swimming pools. In the section of the system prior to the filtration phase it is recommended to use a flow meter based on F6.60 series electromagnetic technology. In the part of the system downstream of the filtration phase it is possible to install a rotor sensor equipped with the new Bluetooth wireless technology of the F3.00.W series which can be combined with the M9.00 series monitor equipped with the practical Help on Board, the guided calibration and system self-diagnostics.

The conventional volume of the compensation tank must be sufficient to contain the displaced volume and any wave motion generated by the maximum number of bathers, the volume generated by the backwashing of at least one filter, the volume necessary to maintain correct suction and avoid dry running. The reintegration of the compensation tank must be activated before the minimum level is reached to avoid the stand-by of the pumps. The importance of carefully monitoring the volume of water is therefore evident. To monitor the volume inside the compensation tank, an HF6 series hydrostatic level sensor can be applied which can be combined with the M9.10 series monitors. The same transmitter can also be installed on the sand filter to check its efficiency level and plan backwashing operations.
