Abstract

1517280 Liquid level detectors F A RICHMOND 23 May 1975 [17 Sept 1974 22 April 1975] 40332/74 and 16484/75 Heading G1H A liquid level indicator comprises an element such as a magnet 8 which can be moved by a float 14 in response to changes in liquid level in a tank, e.g. of a road tanker, a device such as a reed switch 28, for sensing movement of the magnet 8, visual and/or audible warning means connected to the sensing device to give a warning when the liquid reaches a desired maximum level, and testing means operable non-magnetically to simulate the maximum level. As shown the indicator can be tested by supplying compressed air to a bore 24 to raise a piston 20, 22 coupled to the magnet 8. Alternatively, the magnet 8 can be raised, for testing, by compressed air supplied to one face of a flexible diaphragm, by levers, or by a manually-gripped member attached to the magnet 8. Instead of a magnet and reed switch, the indicator may comprise a variable inductor or capacitor. The indicator may also control a pump for supplying liquid to the tank.
