Introducing our cutting-edge Wall-Mount Ultrasonic Flow Meter – the WUFS 904. Utilising transfer time technology, this innovative flow meter is designed with an FPGA chip and low-voltage broadband pulse transmission. It comes with the flexibility of both Clamp-On and Insertion type sensors, enabling you to choose the best option for your application.
The WUFS 901 features a 240*128 backlit LCD display with a user-friendly menu selection and 4- line display. The totalized flow can be measured on a daily, monthly, and yearly basis. Additionally, it offers parallel operation of positive, negative, and net flow totalises with a scale factor (span) and BTU capacity. The totalise pulse and frequency output are transmitted via relay and open collector.
Suitable for Pipe Sizes from DN 15 to DN 1000
