A range of liquid level and flow sensors for domestic boilers, chillers, condensate chambers, circulating water systems, and other HVAC equipment is available. FS Series interlocked flow sensors, available in Noryl, brass, or copper construction, provide fire-up protection for boilers by sensing water presence/flow prior to ignition, eliminating the false triggering associated with pressure sensing. The liquid level sensors have operating temperatures up to 212 degrees F (100 degrees C). Options on the liquid level sensors include tank side-entry sensors in polyethylene or stainless steel, top and bottom tank-entry sensors in stainless steel or brass, and high-pressure-resistant models. Liquid level sensors for condensate overflow protection monitor tray water levels and have a pump out/alarm function.
