But, in the case of a solution, it becomes important to analyze the compatibility of materials. In cases where the liquid that we want to pump is water, corrosion is not a major issue. Selecting the appropriate material is one of the main criteria while fixing on the right float switch.

Choosing the right material to avoid corrosion.

For example, if the pump works with 24 V, 220 V and/or needs an ATEX approval, the float switch must also be compatible with this value. This means that they must have the same specification. Here, we must ensure that the float switch we acquire has the same connection so that it can stop the pump when the water goes below the desired levels.įurthermore, the current between the float switch and pump must match as well. In most of the cases where a pump is used, the pump has a changeover contact with 3 wires.

The electrical connection between the float switch and the pump.

Float switches excel in these applications, providing reliable measurements for a long time, with minimal installation and maintenance required. One of the most common types of level measurement applications involves a storage tank of non-corrosive liquid (for example, water, the most common liquid substance on our planet), at ambient temperature. A simple solution for simple problemsĭifferent types of measurements require different devices. A float switch can be installed relatively quickly by one person.

In some cases, installing other level measurement devices might require moving the pump, which is significantly more difficult. It is so simple in fact that it is a stretch to call it installation: you just need to put the float switch into the tank, make sure that the cable is long enough that the device can travel up and down the tank as the level of liquid rises and ebbs, and that’s it.

Easy installation and versatilityĬompared to other devices available in the market, it is pretty easy to install a float switch.

Other, more complicated methods of level measurement, like conductive, capacitive, and pressure, certainly last longer, but they are also much more expensive. The main advantage of a float switch, which makes it one of the most popular options for liquid level measurement, is the low cost. Advantages of float switch Float switches are cheap It can be attached to a submersible pump or a pump that sits outside the tank and it protects the pump from running if the water is low. If a standard point level float switch will not work for the application, Madison can custom engineer a solution in as little as 4 days, once the requirements are established.A float switch is a small device enclosed in a waterproof case used to turn a pump on and off relative to the water level in the tank. Madison’s trained experts will consider fluid composition, chemical compatibility, container size and shape, agitation and by-products (foam or vapor), level range and required 3rd party certification(s). Madison’s industry expertise is not only in the manufacture of high-quality point level float switches, but also in the recommendation of the proper point level float switch.

Check out our line of continuous level sensors. Multi-level float switches can be configured for specific applications. General applications for point level sensors include high-low level alarm triggers, overflow or spill prevention, and pump control. This provides an OEM with the advantage of using only one or two sensors for their application instead of several. Because OEMs need sensors for tanks that vary in width and height, certain point level float switches are offered with field-adjustable stem lengths. They operate in an on/off state, and are used to control an external device such as an alarm or an on/off switch.

Madison point level float switches use reed switch technology that is simple, reliable, and durable. Well-known point level switch technologies from Madison Company are available such as optical sensors, conductivity sensors, or float switches with reed switch technology, among others. When containers are closed or inaccessible, OEMs rely on point level measurement sensors, combined with remote alarms and/or pump controls, to maintain high/low levels.
