Industrial Flow Switch
Starts/Stops Electronically Operated Equipment When Flow or No-Flow Condition Occurs

Originally developed for the fire protection industry, the materials of construction, operation and dependability of the Taco Industrial Flow Switch are superior to any other product on the market. It is overwhelmingly preferred by boiler manufacturers and comes with the industry’s only 3-year warranty. The Taco Industrial Flow Switch (IFS) starts or stops electronically operated equipment when a flow or no flow condition occurs. The IFS can be used in 1” to 8” liquid flow lines, carrying water or any nonhazardous fluid not harmful to brass, stainless steel or EPDM. It is used in a wide variety of applications including heating systems, domestic water boosters, process work, water systems, chillers and on low mass boilers.
