The UDM 5 flow meter is a compact, non-invasive solution for precise measurement of water flow in pipelines. Thanks to ultrasonic clamp-on technology, installation is carried out without any intervention in the pipe system. The device offers a measurement accuracy of ±2%, supports 4–20 mA as well as RS485/MODBUS, and is suitable for pipe sizes from DN15 to DN50 made of stainless steel, PVC, copper, or PPR. The color LCD display and easy integration make the UDM 5 ideal for industrial applications.
