University Boiler Tank Guided Wave Level Measurement

When a Midwest university needed reliable level measurement of their boiler tanks, they turned to Flowline. The boilers heat and recirculate hot water throughout their stadium, locker rooms and training facility. They were installed with a metal high and low level float switch mounted in external standpipes. But they failed every 1-2 years due to scaling or corrosion and became a nuisance. On top of that, the replacement lead time averaged six weeks. The maintenance manager said, “That’s an eternity. I need a reliable metal level transmitter that mounts in a standpipe and is unaffected by scaling or corrosion. Additionally, I want a display that indicates in gallons and actuates alarms.” For these reasons, Flowline suggested our LG10 guided wave sensor coupled with our LI55 level controller. The guided wave sensors provide maintenance free level data to the indicators, which actuate the alarms and repeat the 4-20 mA signal to the building management system. Flowline is reliable level measurement.
