SERIES HFM Handheld Doppler (non-invasive) Flowmeter

APPLICATIONS

The normal fields of application are where conventional flowmeters do not work or create problems.  Doppler flowmeters are usually more cost-effective in that they do not vary in price with an increase in pipe size.  These instruments normally require no change in piping system and installation is fast and inexpensive.
