Creative Sensor Technology - 1 Inch Enhanced Low Flow Sensor | Noryl tee type | MNPT connections | 3-Wire Scaled Pulse Output SP3 Version for Hunter Hydrawise Controllers 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 sprinklers or stuck zone valves are available for all systems using Hunter Hydrawise™ controllers. The ELF with proven reliable technology, is easy to install making it easy to conserve water, save money and maintain landscapes. The ELF SP3 flow sensor matches well with the Hunter Hydrawise™ series of controllers. The output is a scaled pulse. The ELF has a measurement range from 0.2 to 20 GPM Features Flow Measurement Range: .20 to 20 GPM 3 Wire Scaled Pulse output compatible with Hunter Hydrawise Controllers. Output is a scaled 1 pulse = 1 gallon Working Pressure Rating: 240 PSI LED indicator on Sensor Friction loss at full flow averages 0.20 PSI 1'' Male Pipe Thread Connections Simple to connect: 3 color coded wire leads attach to the Power and Sensor terminal of all Hydrawise controller models. Wire may be extended up to 1,000 feet Follow installation instructions for each controller model Install above or below grade on horizontal or vertical pipe. No need for straight pipe lengths before or after the sensor: The mounting tee straightens the flow Master valve may be directly threaded directly onto the downstream side Installed length with a valve is under 12 inches, fitting in a rectangular valve box. *The SP3 models can be identified by three wire leads, colored red white and blue and an LED in the black sealant where the wire leads enter the sensor insert. 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. Designed for the harsh environment of irrigation service, Creative Sensor Technology now warranties all of its sensor electronics with a lifetime replacement guarantee.
