A spare or replacement manifold flow meter designed to fit our range of underfloor heating manifolds with 1/2″ gauge.

The flow meter allows the flow rate to be set on each manifold port between 0 and 5 litres per minute. The red marker inside the tube indicates the current flow rate. The tube can also be easily unscrewed if you ever need to clean the flow meter.

NOTE: these flow meters will NOT fit Emmett Mk 1 manifolds as they are too wide

How to adjust the flow rate

1. Remove the red cap at the base of the flow meter and
2. Using your fingers (no tools) turn the black screw clockwise to decrease the flow and anti-clockwise to increase the flow. Do not force the screw more than two full turns as this will damage the flow meter
3. The red marker will rise or fall to indicate the flow rate you have set
4. Once the desired flow rate is set replace the red cap
