Horizontal liquid level float switches are used when access to the top of the tank is not possible or ideal. Convenient mounting in the side of the tank provides the flexibility to choose the exact desired liquid level switching point. Side mount float switches are an economic choice and can be used in conjunction with high level alarms or low level alarms. The floats can be made to be mounted internally or externally, ensuring that they can be placed easily and exactly where you desire without a high amount of difficulty. Our float switches have many custom options, such as materials of construction (stainless steel and polypropylene) and SPST or SPDT reed switches.
