Flow Sensor - leak detected notice but no leak

I have a DIGITEN G3/4" Brass Water Flow Sensor, Hall Effect Liquid Flow Meter Flowmeter Counter installed between my backflow preventer and 3 zones of control valves. The system is all drip with 2 and 5 gallon emitters so I've been able to back my way into the calculation of clicks per gallon. This is set at 1250.

The number of gallons shown in the "Watered" display for each zone appears to be accurate. The sensor shows "Overall water leaked since the flow meter was installed 0 gallon".

I am getting a leak notification on my phone with each watering. I can find no further information nor can I find a log.

  I have the same problem with a flow meter that pulses for each .1 gallon.

  It looks to me like the RainMachine starts counting pulses from the flow meter the instant it shuts off the last zone in a program.

  With a more sensitive flow meter like yours, you will detect a small amount of water flowing as the valve closes and pipes re-pressurize.  It would be ideal if there was a few second delay before it looked for a leak.

  Thank you for the reference. I agree 100% with the poster who recommended a user-defined gallon threshold for leak identification. I don't care about 5 or 10 gallons but I want to know when it's leaking hundreds.
