Can one frequency converter be used for two pumps connected in series? One pump is connected to an inverter while the other is not, in order to control the flow rate in this way

Variable frequency control should work for the pump located near the outlet, but it is necessary to consider the pressure-bearing capacity of both the pump and the pipes, with special attention to the pump’s sealing
Pressure sensors can be used to control the system pressure; if one water pump cannot meet the required frequency, another water pump is activated
Two water pumps and one frequency converter can be used to achieve this.
The positive flow rate in a series connection is the same; the flow rate of the second unit can be lower than that of the first unit
Isn’t this just pressure boosting? Pressure reduction is achieved using control valves, while pressure boosting is done with pumps. The pressure measurement points located downstream of the pipeline need to be selected carefully
