Finally a reliable and affordable solution to communicate ‘tank full’ signal to pump controllers over long distances without the need for grid power at the tank site. Solar-powered tank sensor transmits signal wirelessly back to any solar pump controller, AC pump or VFD.
——–
Avoid trenching thousands of feet of tank full sensor wire! After years of customer requests and development, comes our easy to use wireless tank full sensor. No more trenching, no more running hundreds of feet of wire, no more damaged underground wires! Compatible with both Solar Pumps and AC Pumps.
Units come with a solar powered transmitter with panel and receiver to either be powered by AC power or solar. Plug the units into their power source, hook up your float valve, connect to your pump controller and you are ready to go. Tested at over 2.5 miles line of sight (moderately flat land with trees and building in-between, will not work between two valleys with large hills blocking the signal). Never trench signal wires again!

| Receivers/Transmitters Base Units | |
| Input Voltage | 12-24V DC, 0.8A minimum |
| Output Relay Max Load and Output Options | -1A, 24V Resistive Load Dry Contacts, Latching Signal Relay (primary relay)-5A, 250VAC Pilot Duty Relay (secondary relay) -AO: Active Open, Open circuit when pump is running, Usually for solar pump controllers and some VFD’s -AC: Active Closed, Short terminals when pump is running, Usually for AC pumps and AC contactors |
| Tank Full Input | -Float switch or capacitive moisture sensing-Tank Full Activates (pump off) when inputs shorted together or moisture sensed-5 Second Activation/Deactivation Delay |
| Maximum Range | -Rated for 2.5 miles line of sight-5 miles theoretical with ideal antenna placement |
| Wireless Technology | -433MHz LORA Spread Spectrum-Encrypted to prevent interference and crosstalk-No real world limit to number of units in the same area |
