Getting the Best Out Of A Proper Water Tank Level Switch

Storing water in case of a water shortage is important. You also want proper pump and water level management, to avert any water waste from overflowing tanks. Proper management also ensures your tank’s water level is always appropriate. Accomplish this with a water tank switch.

Choosing a Wiring Model

Begin by considering available wiring models for a water tank float switch:

  • Single float switch
  • Two float switches
  • 2-Wire pump with the Kari float switch
  • 3-Wire pump with the Kari float switch

Balance preference with desired performance. For ease of wiring and installation, the two-wire, single-throw float switch is best. This switch turns the pump on or off, but in this basic mode the float switch can short-cycle, causing your pump motor to burn out. Protect your pump motor by considering the other wiring models for a water tank level switch.

The next option is two float switches. These solve the problem of pump motor short cycling by hysteresis, which is a time delay on the switches. The two switches coordinate to determine when the pump turns on and off. Water level falling below the lower switch triggers the pump to run until the water level rises above the upper switch.

This two-switch wiring model may seem best in creating a reliable hysteresis circuit for water level control. However, you can achieve the same efficiency with only one float switch and two wires. You need the KARI series 2L float switch. As this single switch rises with the water level, it tilts to one side, allowing its pre-programmed control circuit to respond appropriately.

Compared to the two previous wiring approaches, this third option seems straightforward. You can still opt for the 3-wire pump control with the incorporation of the Kari float switch. This option presents additional efficiency and features, such as an alarm signal.

Follow Available Instructions and Diagrams

After choosing one of the wiring options, the next step is the most important. Be sure to follow the schematic diagrams that come with each product. Following the manufacturer’s instructions will not only ensure the pump switch and pump motor work properly, but also prevent malfunctions. Should the wiring be too challenging, you can still seek the help of professionals to get the job done.

Properly installing a water tank level switch gives you control over your pump motor and water levels. You only need to identify the most appropriate wiring approach and switch that suits your needs. Carrying out the wiring is less challenging when you follow available manufacturer’s instructions and diagrams.
