IWB is the leading supplier of energy, water and telecommunications in the Basel region of Switzerland. IWB maintains drinking water lines of around 525 km in length and supplies around 190,000 residents, small and medium-sized companies, industry and administration with drinking water of very high quality. To ensure this water supply, IWB relies on monitoring systems such as the ultrasonic fl ow switch from Anderson-Negele to protect against the dry running of pumps and to provide reliable fl ow monitoring in the supply lines.
Flow switches are installed in the supply lines of every pump train. These protect the pumps against dry running, and monitor and ensure the tightness of fl aps and check valves.
