The Enhanced Low Flow (ELF) sensor from Creative Sensor Technology measures the rate of flow in small diameter closed pipe irrigation systems.

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 output signal of the ELF is also the same 2-wire linear frequency produced by our FSI series sensors and compatible with most SMART irrigation controllers.

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.
