Polypipe UFH Flow meters - does anyone know the measuring scale?

[Amarka]

Hi all. I have a Polypipe UFH manifold with flow meters for each circuit. I’ve worked out the pipe length and know what flow rate to achieve BUT the flow meters do not have any scale. All I have is min (top) and max (bottom) and nothing in between! The Polypipe product code is PB129FM for the steel manifold. It’s looks like I have an older version since the newer versions online have some sort of scale but still difficult to read off the net. I’ve emailed Polypipe but not heard back yet. Thanks all

The later flow meters as you would expect are marked in ltr/min they are marked 0 to 6
Latest manifolds are more or less self balancing .
Even if you have original polypipe pipe layout don't be too sure of pipe length. The coils sent are always to long and the tendency is to 'use them up' rather than cut lengths to waste.

Thanks exedon2. 0-6 is a good starting point. I’ll aim for half-way and see how the different circuits heat up and adjust flows.

No problem remember not to screw the flow adjustment spindle too far ie no threads should be showing.

All adjusted and all warm now. Thanks
