Model: HOH-G-H
Description
HOH Handhold Flowmeter is a portable transit-time ultrasonic flowmeter, easy to carry and install.
Practical Applications
The HOH-G-H flow meter can be virtually applied to a wide range of measurements. The measured pipe ranges 20-6000 mm [0.5 – 200 inch]. A variety of liquid applications can be accommodated: ultra-pure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc. Because the instrument and transducers are non-contacting and have no moving parts, the flow meter can not be affected by system pressure, fouling or wear. Standard transducers are rated to 110 ºC. Higher temperatures can be accommodated.
