Additional Flow Sensor Support Flowmec QS200
post by ronjonp on Jul 24, 2019
These ultrasonic flow sensors are designed to replace traditional paddle style sensors like the ones already supported by Rachio.
Could this be added to the list as well? They are not the cheapest sensor but for those who need to get better resolution on low flows these definitely are a step up.
Added chart with specs and k values.

We haven’t had many requests for other sensors but I will make sure our product team (hey @mckynzee) is aware of these.

I just saw this question HERE about adjusting K and offset within the controller. Is this possible? I just acquired a 1" Flomec that has an offset = 0 and K = 0.5386.

Has your team thought anymore about adding a K and offset setting for flow sensors? This would be a nice addition for anyone that does not have the 3 types of flow sensors that you support.

What is the make, model, kfactor, offset?

HERE is a cut sheet from the manufacturers site that has info for 1"-4" on page 2. I also posted this chart in my initial request at the beginning of this thread.
This is what I have:
- make: Flowmec
- model: QS200-10 ( 1" )
- kfactor: 0.5386
- offset: 0

FLOMEC has a QS100 that is a more cost-effective solution to irrigation flow sensing.

@franz Any chance you are about to update the app and could add this QS 100-10 flow sensor as a selection option? This would really help me out for my installation as I have already plumbed the sensor without knowing that the Rachio app doesn’t currently support it.

The K factors for the QS200 SCH 40 & 80 adjoining pipes are shown in the chart on the second page HERE.

These new Flowmec values are now in the Rachio app.
