Hello good night I want to know if it will be possible to connect an electron level to a hydropneumatic because the hydropneumatic is supplied with a cistern and sometimes the tank runs out of water and the hydropneumatic works in a vacuum, to avoid this I have decided to connect it to an electron level so that Do not work when the tank is empty, the question is: can it be done? I clarify that everything will be working at 110 volts. It is the voltage that is handled here in Mexico. Thank you, I hope your answers if you add me a connection diagram I will also appreciate it.
