The perfect flow-control solution
The simplest discharge is when the water flow remains the same no matter how high the water level, i.e. no matter how high the pressure. Depicting the damming up before a flow regulator (h) as a function of the discharge through it (Q) provides the flow regulator's characteristic. The simplest vertical characteristic is shown in Figure 1.
Ideal operating conditions are also a significant factor in getting an ideal solution. In this respect, the aim is to get the biggest possible orifice opening, but avoid the use of moving or electrical parts to minimise the risks of shutdown and clogging.
The characteristics for Mosbaek flow regulators are as close as possible to being vertical for solutions without electrical or moving parts and have the biggest orifice opening.
Calculation models are used to determine the water-pressure and discharge values as a basis for choosing type, dimensions and design of the flow regulator.
