Madison Company offers a series of low-cost radar sensors for continuous level measurement. This product series offers a logical extension to the ultrasonic sensor series, where application conditions are in need of non-contact liquid level measurement, and where ultrasonic level measurement is not acceptable.
As with all Madison products, this radar technology can be designed for your specific level measurement needs, providing unique considerations for materials to be measured, vessel configuration and system interface. These radar level sensors are ideal for reflective liquids that have a foaming surface or vapor conditions beyond ultrasonic wave capabilities.
