Traditional float switches work by opening and closing dry contacts to send electrical signals that set off a low water level alarm. Magnetic reed switches complete the circuit when the float reaches its lowest point. The magnet then disconnects once the water has reached an adequate level again, opening the circuit up. This type of float level switch has a very limited lifespan, primarily because of the mechanical parts involved. If the float level switch fails, there will be malfunctions in the system it controls. Too little water could result in inadequate water pressure and dry running of equipment — which mean expensive repairs and problematic downtime.

We realize that not everyone is ready to make the switch from float level switches. We have also developed our own magnetic reed vertical float switches that connect directly with our WLC Series controller. These float switches have the color coded wire as the physical probe assemblies we produce, making the installation and operation fast, accurate, and easy. Our vertical float switches can contain multiple magnetic reed switches at various heights can be built to be any length requested. The assemblies are manufactured out of stainless steel to minimize any potential issues. In addition, our magnetic reed vertical float switches only take a few days to put together since we keep in stock all the raw materials required to assemble them.

The ultra sound sensors operate by transmitting a burst of high frequency sound waves and then measuring the amount of time it takes for the sound wave to reflect back to the receiver/transmitter. The frequency can be anywhere in the range of 20 KHz to above 100 MHz. The frequency is very application dependent. Ultra sound can be applied to operate in almost any medium; air, water (liquids) or various solid materials. It could be classified as a non-contact level system.
