Flow Sensors
A CST flow sensor connected to a smart controller can sense a broken pipe, stuck zone valve or run-over sprinkler head. The smart controller can close a master valve, stopping the water loss and notify you by email or text.
Save time, labor and money by installing a flow sensor on every irrigation job.

PVC Flow Sensor

ELF (Enhanced Low Flow) Sensor

Saddle Flow Sensor

Brass Flow Sensor
Interface & Control
The ISO4 Isoflow is a signal processor that allows up to four control devices to share one flow sensor and control one master valve.


Pathway Wire Sharing Device
The Pathway S01 provides a reliable cost effective method to add a two wire flow sensor and master valve to installed systems where existing pavement, hardscape, or other landscape features make conventional wiring prohibitavely expensive.
The Best Technology for Irrigation Service
Creative Sensor Technology flow sensors have been engineered specifically for service in the harsh underground, often wet, electrically unstable environment of irrigation service. We detect flow with impeller technology because it is best suited for this application. Our impeller technology has proven to be practical, reliable, and cost effective. The impeller, the single moving part is self- cleaning, aids in troubleshooting and requires no more maintenance than other technologies with no moving parts. Like the solenoid operated diaphragm valve, that has been used for 75 years, the impeller sensor is still the best technology for irrigation service.
Flow sensor models and sizes to fit every sprinkler system and smart controller may be purchased through our distribution network. Call, text, or email us with your questions about products, applications or technical assistance.
