False flow readings from flow sensor.

[Richard L]

Is it possible for you to unbolt the FAV cluster and rest it on something soft and see if you see false reading. It is done on idle.

I try to establish what caused it. Mechanical vibration or electrical signal. Un-clip the sensor and see if the gauge still registers something.

It is mechanical vibration. I was fine with false readings until the weather got real cold here and you can feel the car vibrate more (winter time). Not spraying meth now so it doesn't bother me, but once a week I do turn on the system and spray a little to get the pump moving and sometimes get some false readings.

If I unclip the sensor no false reading I will try on something soft.

We can now concentrate on the mechanical solution.

Hi, do you know if this is compatible with my system :

I think my flow sensor is defective

This is the correct part iof you want to have it replaced.

Or

You can send it back to me for repair. No charge but you have to pay return shipping. Airmail post is ~?10.00.

if its my sensor any warranty from aquamist ?

here some picture of the soft setup :

Yes, there is, it can be repaired or replaced, but you must send it back to me. What is the serial number of your controller? If is under warranty, we will repair or replace and free shipping provided we don't see any strange debris inside.

Out of warranty, we can repair free (not repairing and parts free if it is physically damaged). But you have to pay for the return shipping. Shipping via airmail is very cost effective.

You must put a statement on the outside of the package... "return to manufacturer for repair" or you will be responsible for the import tax and duty.

Send the sensor back to me for closer examination. It is not easy to simulate your present situation if the sensor works as designed on the bench. It is more an operational problem rather a faulty sensor. It is quite a simple design, mechanically.

You appeared to be good with mechanical things, try disassembling and give it a clean. Make sure the sensor is vertical when re-assembling.
