CST - 1'' ELF Series Flow Sensor (2 Wire Frequency) - ELF-T10-N01

Creative Sensor Technology -  1 Inch Enhanced Low Flow Sensor | Noryl tee type | MNPT connections | Standard 2-Wire Frequency Output The Enhanced Low Flow (ELF) sensor from Creative Sensor Technology measures rate of flow in small diameter closed pipe irrigation systems. Now the water saving benefits of detecting leaks, broken sprinkler heads or stuck zone valves are available for smaller systems with lower flow zones. The ELF with proven reliable technology, is easy to install making it easy to conserve water, save money and maintain landscapes. Features Flow Measurement Range: .20 to 20 GPM 2 Wire Frequency output compatible with most smart irrigation controllers  Working Pressure Rating: 240 PSI LED indicator on Sensor Friction loss at full flow averages 0.20 PSI 1'' Male Pipe Thread Connections Install above or below grade on horizontal or vertical pipe. Advantages of ELF Flow Sensors over Water Meters Measures a much wider range of flows Operates without pressure loss Higher pressure rating – 240 psi Easy to install, no special fittings required Simple to clean or service Instead of estimating your water usage, accurately measure it in real time This innovative new design, issued US patent no. 10060774 B1 in 2018, allows this sensor to measure flow rates over a range from .20 to 20 GPM using the proven impeller technology of the other CST flow sensors. The standard sensor output is a digital pulse proportional to flow. The electrical characteristics of the output signal duplicate other two wire digital outputs making this “frequency” output signal compatible with most manufacturer’s “smart” irrigation controller products. The pulse signal will travel up to 2,000 feet without amplification. This new design eliminates the need for straight pipe sections up and downstream of the sensor allowing for installation in tighter spaces. In fact, solenoid valves may be connected directly to the downstream end of threaded ELF versions resulting in a flow sensor/master valve combination less than 12 inches long. Designed for the harsh environment of irrigation service, Creative Sensor Technology now warranties all of its sensor electronics with a lifetime replacement guarantee.
