Hi All
Is there anyone using a flow sensor sized from 1.5″ and upwards that works with OpenSprinkler? Can you share your experiences and what brand and model you have been using?
I want to make sure I don’t run my pump dry when my water level is low
How does the flow sensor size matter? What matters is generally the electrical property not the physical size. Do you have a link or datasheet to your flow sensor?
My supply line to my pump is 2inch and I don’t want to introduce any unnecessary restrictions.
I can see there’s this DN50 Pulse “Stainless Steel Hall Flow Meter Electromagnetic Water Flow Sensor Industrial Fluid Flow Rate Sensor for Plumbing Water Dispenser”
https://a.aliexpress.com/_mLPTuzB. Not sure if this is suitable or how to configure it to stop the station when low flow is detected? Also is this better to be installed before the pump or after the pump for my circumstances?@CoenJC I think the problem might be with that type of sensor is that it pulses very fast and OpenSprinkler make not be able to keep up and will miss lots of pulses.

The current firmware can handle flow sensors up to 20Hz (20 clicks per second). This is mainly due to it using software polling for flow click reading – and that in turn is due to historic reasons (the same firmware has to work on multiple hardware versions, some of which don’t support interrupts on the sensor pins). Long story short: if you must use a faster flow sensor, it is possible to modify the firmware to use interrupt instead of polling to read flow sensor.
