Application
Fire Water & Sprinkler Systems
Flow measurement on fire mains, flow checks on sprinkler installations, and flow switches that confirm emergency safety showers and eyewash stations are working.
Measures: Fire main flow · Sprinkler flow checks · Safety shower activation
Fire Mains
Fixed clamp-on ultrasonic meters measure flow in fire mains without cutting into the pipe or taking the fire protection out of service.
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.
Sprinkler Installation Checks
Safety auditors and sprinkler contractors use portable clamp-on meters to check the flow in sprinkler installations, on carbon steel pipes from DN50 to DN600, without draining or opening the system.
Emergency Safety Showers & Eyewash Stations
A vane flow switch on the inlet water line signals the moment a safety shower or eyewash station is used, so an alarm, beacon or the control room knows someone needs help. The V6 fits 1/2 to 2 in lines and the V4 lines of 1-1/2 in and up, in weatherproof or explosion-proof versions. The same switch confirms flow during the weekly activation test.
Dwyer Series V6 Flotect Mini size Flow Switch for 1/2" to 2" PipesDwyer V6 Flotect compact vane flow switch for liquids, gases and air in 1/2 to 2 in pipes: weatherproof and explosion-proof, up to 2000 psig.
Dwyer Series-V4 Flotect Flow Switches: Weatherproof, Explosion-Proof, Low Flow ProtectionDwyer V4 Flotect vane flow switch for pipes 1-1/2 in and up: weatherproof and explosion-proof, up to 5000 psig, for loss-of-flow protection in hazardous areas.
