    I require 1 set of wireless water level controller ready to use or do we need to make it. I need a system to fill overhead tank of 1.75 mtr height with a single phase pump 220 volts, 1.5 hp which is about 30 meters from the over head tank. 220 volts available at overhead & pump location.

    Is it possible to send me manual & cost of same payment terms.

    The transmitter needs to be installed in open air hence should be water proof & enclosed type. Also receiver unit should be enclosed type.

    I await your reply.
