Abstract
Apparatus for detecting fluid level in a container, comprises a housing adapted to be disposed in the container; a float with an associated magnetic element, the float position corresponding to fluid level in the container; a magnetostrictive sensor disposed inside the housing; and a stick gauge disposed inside the housing; the magnetostrictive sensor and the stick gauge each being operable to determine the float position.
Claims6
A gauging apparatus for measuring liquid quantity in a container comprising:
- a magnetic float in the container with the float position corresponding to the liquid level in the container;
- a dripstick in the form of a housing that is manually withdrawn from the container in relation to the position of the float to obtain a visual reading of the liquid quantity;
- a sensor disposed in said housing that produces an output related to the position of the float and gauging means for receiving the sensor output to determine liquid quantity in the container.
