Sensor dc for shut off the pump is about one metre from the pump.
Equation: x^2 limit x-> 1.2 = 2x
Y= integral x^2 dt =2.4^2=5.76 s
Speed 5.76 m/s. Pump on/off = 1.4 m/s
Without controller : about 4 metres from the pump.
Without controller and vsd : cm to m; 10000 / m ^2= 10 kg/m^2. So, sensor is located = 14.5 m from pump motor.

Vsd is easy to monitor and no impact when changing its value even changing its default setting. Also controller device limits the low and high pressure. Relay open when pressure above 3.5 kg/cm2 and close again below 2.5 kg/cm2, where t=infinitely. Sensor of pressure disconnects power.
