Sensing the presence of liquid of a predetermined specific gravity

The apparatus comprises two liquid level detectors 16, 18 each comprising a float 30 and a pneumatic sensor 38 which responds to the rise and fall of it's corresponding float 30. The two floats are designed to respond to liquids of different specific gravities, e.g. one will float on water but not on petrol and the other will float on both water and petrol. The two sensors provide an indication, such as an audible or visible alarm, of firstly whether a liquid is present and secondly whether the liquid has a specific gravity above or below a predetermined value, e.g. they can indicate whether the liquid is water or a hydrocarbon. The apparatus is intended for use in sumps, such as those found in garage forecourts, to warn of the presence of a hazardous liquid before purging the sump. Sensing apparatus comprising a float mounted on a pivotal arm (see figure 4), and sensing apparatus comprising a float movable relative to a raft (see figures 6, 7 and 8) is also disclosed.

Method and apparatus for automatically sensing the level of a liquid in a reservoir

A liquid level sensor adapted to be installed inside a reservoir of a liquid to be monitored.

An a.c. coil driven by a pulse generator is located at one end of the float path such that the magnetic material of the float is closer to the coil at this one end of the path than at the opposite end, and is thus a variable part of the "core" of the coil which changes in response to the liquid level in the reservoir. The magnetic flux generated by the coil and/or its inductive reactance, also being a function of the variable core and thus a function of the liquid level, can be monitored electrically to provide an indication of the liquid level to an operator. The level sensor can be used to provide a signal at a predetermined level, or to provide an output which is proportional to the level of the liquid ...

Monitoring with a radially magnetized magnet and hall effect sensor

An improved fluid level sensor includes a radially magnetized magnet integrated into a float, and a Hall sensor adapted to monitor the magnet field emitted from the magnet. This arrangement provides a continuously variable signal across a range of travel, such that a controller receiving the signal can produce precise fluid level measurements and detect operational states of an associated device based on fluid behavior. In addition, the present fluid level sensor is suitable for use in harsh service environments, both because it is physically resilient to fouling, and because the controller is capable of detecting fouling by sensor behavior. In the context of a steam cooker, the present fluid level sensor can also sense low-water, overfill and fouling conditions, while remaining relatively insensitive to food residue, water scale buildup, corrosion and foaming.
