A float switch is a type of level sensor, a device used to detect the level of liquid in a tank. Switches can be used as pump controls, indicators, alarms, or to control other devices. One type of float switch uses a mercury switch inside a hinged float. Another common type is a float that raises a rod to activate a microswitch. One pattern uses a tube-mounted reed switch. A float containing magnets surrounds the tube and is guided by it. When the float raises the magnet towards the reed switch, the reed switch closes. Multiple leads can be attached to the tube for different level indications in one assembly. Float switch from drain pump opened A very common application is a sump or condensate pump, where a switch detects a high liquid level in a sump or tank and energizes an electric pump, pumping liquid until the liquid level drops significantly. . The pump will turn off again. Float switches are often adjustable and may contain significant hysteresis. That is, the "on" point of the switch can be much higher than the "off" point. This minimizes the on/off cycles of the associated pumps. Some float switches contain a two-stage switch. When the liquid rises to the first stage trigger point, the associated pump is activated. If the liquid continues to rise (perhaps because the pump failed or was blocked from draining), the second stage is triggered. During this stage, the pumped liquid supply can be switched off, an alarm can be sounded, or both. If level sensing is required within a pressurized vessel, magnets are often used to couple the movement of the float to a switch outside the pressurized volume. . In some cases, a rod running through the stuffing box can be used to operate the switch, but this creates high resistance and can lead to leakage. Successful installation of the float switch minimizes the chances of dirt buildup on the float that impedes its movement. Float switch materials are selected to withstand the adverse effects of corrosive process liquids. In some systems, an appropriately chosen and sized float can be used to detect the interfacial level between two liquids of different densities.

AMI Dual Level Float Tree Assemblies are completely assembled with low-level and high-level floats and ready to install on an atmospheric product water RO tank for continuous monitoring of product water tank levels. When the tank is full, the tank-level high float will signal the water treatment system controller to shut down. When the water level drops, the tank-level-low float will signal the controller to start up and resume production until the tank is full again. The assembly is made from schedule 80 PVC components and includes a threaded bulkhead fitting for installation through a drilled hole in the tank wall. The pre-wired junction box has color-coded leads ready for connection to a the RO system controller - additional wiring (not included) will be required. The buffer between the two floats prevents cycling of the RO pump that can be caused by water surface turbulence as the tank is filling.
Commonly used in RO, UF, NF, MF, and SWRO commercial and ustrial water treatment systems, AMI Dual-Level Float Switch assembly is compatible with any water treatment system with an atmospheric storage tank and equipped with ROC controls with tank level connections.
