Application
Potable Water Networks
Flow metering on drinking water mains and district meters, leak detection and flow surveys, and reservoir level, mostly with clamp-on meters that never touch the water.
Measures: Network flow · Leak detection · Reservoir level

Network & District Metering
Fixed clamp-on ultrasonic meters measure flow on existing mains from DN40 to DN2000, in cast iron, steel, PVC, PE or GRP. Nothing touches the drinking water and the pipe isn't cut, so they suit large or old mains where fitting an inline meter would mean a shutdown. Difficult pipes, such as large GRP mains, use the Uf 800 range.
Ultraflux Minisonic Fixed FlowmeterFaure Herman single-chord clamp-on transit-time ultrasonic flowmeter for liquids, with OLED display, 4-20 mA output, two contact outputs and a 1.8 GB data logger.
Ultraflux Uf821 Ultrasonic Fixed FlowmeterFaure Herman fixed clamp-on ultrasonic flowmeter for liquids: up to 4 measuring points per unit, accuracy to 0.5% of reading, on steel, PVC, cast iron or stainless pipes.
Leak Detection & Flow Surveys
Portable clamp-on meters let network and plant operators measure flow anywhere for a few hours or days: to find leaks, survey a district or check an installed meter, on pipes from DN40 to DN1000.
Inline Flow Meters
Where a new pipe section is installed, flanged electromagnetic meters give a full-bore measurement with no moving parts, with the flow rate and totals on the display.

Reservoir & Tank Level
Non-contact ultrasonic transmitters measure the level in service reservoirs and storage tanks, with nothing in the water.
