Fields of application
This flowmeter can be installed on cold and hot water pipes throughout the building (pure water manufacturing processes, equipment cleaning and cooling processes). The flowmeter can also be mounted inside equipment where there is a dense network of small-diameter pipes (semiconductor manufacturing equipment).
