The turbine flowmeters are available in 0.5 to 12 in. (13 to 305 mm) pipe sizes and are designed for cold water up to 120¿F (50¿C) or with fiberglass components for hot water up to 250¿F. The turbine rotation is transferred using magnets from the totally sealed flow chamber to the counter. The counter has a trickle dial to indicate flow of the turbine at an extremely low flow rate. The bright-faced, hermetically sealed counter design can be turned 360¿ for convenient reading. All counters are nonresettable and tamper-proof.
