Wireless Water Tank Sensor for Remote Pump Shutoff

Wireless Tank Sensors

When it comes to connecting tank full sensors to your RPS controller, sometimes your water tank can be several hundreds of feet away. Running wire over a few hundred feet away can be a hassle, especially if you need to bury the line in conduit. After years of customer requests and development, comes an easy-to-use wireless tank full sensor, recently upgraded for 24-hour options and AC pumps. No more trenching, no more running hundreds of feet of wire, and no more damaged underground wires. 

Standard units come with solar panels to operate both the transmitter and receiver and are perfect for RPS standard and Pro Systems. Plug the units into their solar panels, hook up your float switch or stainless tank full probe, connect to your pump controller and you are ready to go. The 24-hour option comes with batteries for backup power and the AC options come with 30A 120V/240V AC contactors to control large loads. The signal has been tested up to 2.5 miles and could potentially reach 5+ miles with the right antenna mounting location. The signal can travel through trees and other objects that can obscure the actual line of sight. However, the signal can not travel between two valleys with a mountain or hill in between. Next, we will go into the breakdown of each type of unit. Note that every kit comes with a receiver and transmitter. 

Daytime Unit

The daytime unit runs during the day and uses 2 wires to send open and close signals into a control box. This version of sensors need to be plugged into a control box that accepts input for a tank full status. Systems with no sensor inputs or control boxes are not compatible. On the RPS 100V controller the receiver wires into the COM 2 and TH terminals. On the RPS Pro system the receiver wires into the COM port plug. Float and pressure switches get wired into the transmitter, which has a 2 wire input. 

24 Hour Solar Pump Unit

The 24 hour solar pump unit operates exactly like the daytime unit with the added benefit of having a battery backup installed. On a full charge the battery back can last up to several days. 

120V AC Pump Unit

The 120V AC pump operates off 120V AC power to power the unit. This version uses a set of contactors that open and close to control the flow of electricity to the pump. The receiver is housed in a box with a cover. Rather than using sensor inputs the receiver sends a signal to the contactors to either open or close. This unit is compatible with most single phase 120V AC pumps. The transmitter comes with a battery much like the 24 hour solar pump kit. 

240V AC Pump Unit

The 240V AC pump unit is wired and boxed just like the 120V AC but instead used on 240V AC systems. The receiver has contactors that are rated for 240V AC power.
