Madison has been manufacturing a wide variety of liquid level sensing products since 1959. The company's product catalogue includes switches, floats, indicators and sensors in different body and float materials. These products are widely used in food & beverage, chemical, paint and oil industries. Madison float switches are used to measure liquid levels using sensors with an electrical contact output. These switches are also available in optical sensor and conductivity sensor variants that can withstand extreme temperatures, pressures and vibrations. Liquid level switches by Madison feature a high-level alarm and are used in various liquid control systems to prevent spill and overflow of fluids. The brand's tape level indicators use a magnetic float to read the level of liquid and are widely used in drums and storage tanks.
