Long Awaited ELF is Here


Creative Sensor Technology's 

Enhanced Low Flow Meter


A new impeller type flow meter that is so unique it has been issued US Patent No. 10, 060,774 B1. 

What’s new about an impeller flow meter you ask? 

  • Flow readings from 0.25 to 25 gpm 

  • No requirement for straight pipe before or after the meter 

  • Available in 3/4” PVC socket or 1 inch threaded Noryl versions 


Why flow sensors? 

A broken 1 1/2 '' PVC pipe running at 50 psi will discharge over 10,000 gallons in 30 minutes or over 168,000 gallons running for 8 hours. Flow sensors are capable of detecting these leaks to prevent water loss. 

Our goal as good stewards of our resources is to provide the most water efficient irrigation design, best sprinkler selection and most efficeint scheduling possible. We can employ moisture sensing devices or input ET calcuations to adjust start frequency or run times. But all the water saving practices we design into our system can be lost with an undetected pipe break or valve malfunction.
