How to install a float switch for a pump?

We can help you calculate how much liquid level you’ll need to satisfy your pump’s requirements. Float switch installation requires you to mount the device with some way of fixing the cable above the tank or well. There is a mounting bracket available for the Kari Float Switch that uses a snug wedge to fix the cable into place.

What is a float switch on a tank?

A float switch detects the level of a liquid in a tank. Based on the water level, it will open or close an electrical circuit generally used to pump water in or out of the tank. How does a float switch work? A float switch moves with the liquid level up and down. An internal mechanical switch opens or closes an electrical circuit with gravity.

What is a pump down float switch used for?

A Pump Down Float Switch, also known as Normally Open, closes the circuit on the rise and is typically used to turn the pump off when the float is in the down position. So, a pump could be set to turn off when the water level in the storage tank reaches a predetermined low level.

What is the landing point of a float switch?

In both schematics, terminal 1 in the control circuitry represents the landing point for the float switch’s (+) wire, and terminal 2 for the (-) wire. So there we have it. A two-wire float switch that can easily be used for turning a pump on or off.

How do you use a float switch on a water pump?

A two-wire float switch that can easily be used for turning a pump on or off. Mount or suspend your switch at the desired level, get your wires into a water-tight junction box (or out of the liquid containment area and then into a junction box), check the connections back to your control and power equipment, and you’re done.

What is the position of the float switch?

The position of the float switch is close to bilge pump. The float switch should be sitting equal with the bilge pump or slightly higher. The float switch sits in this position so that the bilge pump isnt activated until the water level reaches the pump.

What are the installation scenarios for a normally open float switch?

Installation scenarios might include a Normally Open float switch turning on a pump to empty a tank (Control Schematic 2), or a Normally Closed float switch turning off a pump that fills a tank (Control Schematic 1).

How does a bilge pump float switch work?

A boats bilge pump float switch turns on when theres enough water in the bilge to float it, and then it shuts off the pump once the water is pumped out.

How do single point Float switches work?

Single point float switches work with 3 sensor rods (Reference, Start & Stop) that work in conjunction to turn on and off your water pump automatically. This helps keep water levels at a consistent level.

What is a float switch on a tank?

A float switch detects the level of a liquid in a tank. Based on the water level, it will open or close an electrical circuit generally used to pump water in or out of the tank. How does a float switch work? A float switch moves with the liquid level up and down. An internal mechanical switch opens or closes an electrical circuit with gravity.

Why do float switches have a minimum and maximum cable length?

These switches have a minimum and a maximum cable length to ensure proper function. Therefore, they can be installed differently if its used to start or stop the inflow of liquid. Figure 3: Float switch with a counterweight in a water application.

How does a float switch work on a cooling tower?

New Float Switch Working Principle. Float switches and water level controls usually start out closed, meaning there are no alarms that need to be triggered because the water level is at the predetermined height. Once the cooling tower starts using the water for its industrial processes, the water level starts dropping.
