How it works
When a fluid flows through the vertical tapered metering tube the float will rise until a point of equilibrium is reached where the downward weight of the float is balanced by the upward thrust of the fluid. This point will represent a specific flow rate. If the flowrate increases the float will rise to a new point where the new upward thrust of the fluid is balanced by the weight of the float.
The flowmeter should be installed with the flow vertically upwards through the flowmeter. For accurate results ensure that the pipework is vertical to within 2/3 degrees. The standard socket connections are for use with rigid PVC imperial pipe 3/4″. When used with liquids valves may be placed upstream or downstream of the flowmeter.
All DNFM flowmeters are individually calibrated with water. The graduated scale depends on three factors: the shape and weight of the float, the size and taper of the measuring tube and the density and viscosity of the fluid.
