The DUS-F6 ultrasonic flow meter from Prisma Instruments has been specially designed to meet the recurring needs for non-intrusive metering of water and other clean liquids in residential or industrial installations. It is available in 2 models, the first equipped with transducers that adapt to pipes from DN15 to DN40, and the second from DN50 to DN65. It can be installed in a few seconds by placing it around the pipe, without the need to stop the flow or drain the circuit. Due to its compact size, the DUS-F6 meter can be easily installed in a confined space, or on several pipes when they are very close to each other. Optionally, equipped with non-intrusive PT1000 temperature probes, the DUS-E6 model will act as a thermal and cooling energy meter for HVAC installations and other building management. In addition, it also has a rich RS485 Modbus RTU network functionality and can therefore be easily connected to a GTC. Its very refined design, its many features, its excellent quality performance ratio justify its success with professionals in the sector.
