The Enhanced Low Flow (ELF) sensor from Creative Sensor Technology measures rate of flow in small diameter closed pipe irrigation systems.
This innovative new design, allows this sensor to measure flow rates over a range from 0.75 to 75 LPM using the proven impeller technology of the other CST flow sensors. Two models are available a 3/4” PVC socket or 1” threaded design. 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.
This flow sensor is compatible with the Rainbird ESP-ME3 Modular Controller. (not compatible with the Hunter Hydrawise range)
Unique design of custom molded mounting tee
  • Provides improved minimum flow detection, expanded measurement range and more repeatable outputs.
  • Eliminates the need for straight pipe sections before and after installed sensor.
Electronics fully encapsulated in proprietary epoxy compound
  • Sensor designed for installation below grade and underwater. Covered by lifetime warranty
Distinctive lightweight 4 blade-ed impeller
  • HDPE material reduces the minimum flow rate detection, resists wear, corrosion and fouling
Integral High Clearance bearing
  • Self cleaning, flushes out solids, wear resistant
Improved Detection Circuitry
  • Circuit contains superior over-voltage and over-current protection, noise filtering and signal conditioning.
Removable flow sensing insert with o-ring seal
  • Captive retaining nut holds insert in place. Simple, one-hand service in a valve box Impeller bearing and shaft located out of flow path
  • Easy to troubleshoot
