Hi George,
I don’t think what I’m about to say will help, but I’m sharing just in case it does.
I have a 14kW Ecodan with the FTC5 control unit. My installer fitted the EMP3-M which allowed me to claim the MMSP rebate. I’m not as brave as you so I’m using their MELCloud system to monitor (and in fact control) my system.
Anyway, here’s my SIKA unit that they use to monitor the flow. Feel free to ask if you want any other photos, there are lot of bits and pieces in my system.
