I have the Snow Stg 2 with Safe Injection. I know the SI goes off at <188ml/min. I want to try and integrate a flow meter that I can hook up to the Aux input on my ZT-2. Does anyone know where I can find one that might work? I looked at McMaster by the way and didnt see anything that looked compatible.
Abner please read this because I am betting you will have an answer.

 

What is the outpute of the flowmeter you already have. If its a 1-5V signal you should be able to use a multimeter to see what the voltage is at 188ml/min and set up the fault band accordingly on the ZT2

 

cp: i use the aquamist dds3 flow sensor voltage output fed to the zeitronix aux input.

 

I think The snow system uses a flow switch, it does not give a progressive voltage with flow - just an on/off output.

You really need to get a proper flow sensor with a 0-5V output relative to fluid flow.
