Ultrasonic Level Sensors

UltrasonicMadison Company offers a complete line of standard and advanced ultrasonic level measurement sensors for liquids. These products continue to meet demanding applications in many markets, at competitive prices.

In addition, Madison Company has the engineering capabilities to design these sensors for your specific non-contact level measurement needs, providing unique considerations for materials to be measured, vessel configuration and system interfacing. The microprocessor-based circuits provide a temperature-compensated signal for improved accuracy. All models have the ability to filter false echoes produced by peripheral obstructions. Continuous level measurement can be provided in a range of 0.33' to 90' (0.10m to 27.4m)with several power and programmability options. Point level can also be obtained using a Madison panel meter or PLC (Programmable Logic Controller).
