How to make assembly between induction motor,centrifugal pump and open/close valve for tank in simulink. Please guide to work out my query

I want to measure the level of water tank,as the level goes below set point (25)valve should be opened and as it is above setpoint(75)then valve should be closed,so that water which is pumped from another tank cannot enter or viceversa. I have difficulty in selecting valve assembly and level indicator

I would also like to know how to assemble the induction motor along with the centrifugal pump.

There are a few blocks in Simscape Fluids that you can use to model the tank

All include PS ports indicating the amount of water inside. You may use that to show water level and design your controller. It sounds like a simple on-off type of valve is sufficient to open or shut the water flow.

Simscape Fluids also contains a few centrifugal pump blocks. Just choose the physical domain you need and pick the right one.

Simscape Electrical contains motor blocks. The mechanical rotational ports of the motor and the pump can be connected to allow the motor to drive the pump.

As starters, I would recommend using ideal velocity sources as idealized motor first to drive the pump, just to test the parametrization of the pump. Similary, ideal velocity or torque sources can be connected to the motor to test its parameterization. After that, putting the pump and the motor together should be much easier.
