The inverter controls the speed of the pump
Thread Content
At the site, frequency converters are used to control the speed of industrial water pumps and domestic water pumps. Indirectly, the frequency converter can be controlled by measuring pressure, flow rate, or liquid level. Generally speaking, which of these parameters makes it easier to achieve effective control: pressure, flow rate, or liquid level? Please give some advice
Generally, frequency conversion control is achieved based on the pressure of the medium in the outlet pipe; simply installing a pressure sensor on the outlet pipe is sufficient.
:We use flow rate to control the speed of the variable-frequency pump
Different control points are selected based on the requirements at the pump outlet: pressure control is used when pressure is the concern, and flow control is used when flow rate is important. The main factor in determining the pump speed is the intended purpose.
It depends on the goal you want to achieve; consider the object in question

Is there a quantitative relationship between frequency and pump speed?
Specifically, it depends on the on-site process requirements; from a control perspective alone, pressure is relatively easy to control
