Which Flowmeter?

I'm perfectly happy with my Koolance FM-17.

Can one use AC flowmeter on mcubed t-balancer BigNG ?

There is only one KING...:D

Actually I have three of them and don't even test anymore...I just like them. I've had two in my system as general health indicators (one for each loop) for over a year now.

I guess I like the analog types.... no wires, software, or calibrations to screw up and they are very low restriction compared to some of the impeller types...:D

Every now and then you can find these on ebay for around $50 a pop..
