Abstract
A liquid level transducer for a tank, such as a railroad tank car or the like, includes a mounting head connected to the tank and a sensor assembly extending into the tank from the mounting head. The sensor assembly includes a sensor tube located in the tank and a gauging rod assembly positioned in the sensor tube. The gauging rod assembly can be pulled out of the tank until it magnetically couples with a magnetic float that surrounds the sensor tube. The float moves in response to a change in liquid level and the magnetic coupling provides the user with a visual indication of the liquid level. A sensor board extends along a length of the gauging rod assembly and is responsive to movement of the float for electronically determining the liquid level without the need to magnetically couple the gauging rod assembly to the float.
