The replacement flow meter allows the water flow through an individual underfloor heating pipe loop to be adjusted between 0 and 3 litres per minute. Setting each circuit to the flow rate specified in the UFH design helps balance the manifold and distribute heat correctly throughout the system. The integrated glass scale provides a clear visual indication of the current flow rate, making individual circuits easier to check and adjust during commissioning or system maintenance. The built-in shut-off function also allows the relevant circuit to be isolated by turning the adjustment spindle. This version has a 0-3 litre/min scale and a ½″ male BSP connection. Before ordering, check the scale and connection on the existing flow meter to confirm compatibility. Where the manifold requires a wider adjustment range, select the 0-5 litre/min replacement flow meter.
