Ultrasonic Clamp-On Flow Measurement

Ultrasonic Clamp-On Flow Measurement

As part of the renovation of the Schaanwald drinking water reservoir, the entire structure was replaced—including all piping. Despite these ideal conditions for installing a magnetic-inductive flowmeter, we deliberately chose an ultrasonic clamp-on flowmeter from Flexim.
An important milestone has been reached

Comments of our customers

Bild_Testimonial
For us, the key advantages were the ease of installation, the ability to provide accurate data at low flow rates, and hygienically sound measurement. The clamp-on technology can also be seamlessly integrated into existing water supply systems.

The renovation and technical upgrade of the Ländte wastewater pumping station marked a major step toward the future. The modern control system and user-friendly touch panel not only make operations more efficient but also safer. We were particularly impressed by the well-thought-out implementation of safety measures in the storm water basin area. Our collaboration with STEBATEC was constructive, reliable, and solution-oriented throughout the process.

For us, the Scheidegger damper actuators is the best solution. For all our applications in the primary system with pipes up to DN 1000mm, we always have the same mechanical and electrical interfaces. The fact that even the largest dampers can be operated with a drive of only 24VDC allows us to operate our systems safely even in the event of a power failure without expensive UPS systems.
