Abstract

1533655 Liquid level indicators NU-WAY HEATING PLANTS Ltd 14 Jan 1976 [27 Nov 1974] 51279/74 Heading G1H A liquid level detecting apparatus comprises a float chamber 11 having a lower open end 12 and an upper end 13 connected by a pipe 14 to an upper level of a boiler 10, a float 16 in the chamber 11, means such as an electrical switch 18 to provide an indication when the float is at a predetermined position in the chamber, a valve 15 for closing-off the communication between the upper end 13 and the boiler, and means, controlled by a second valve 21, for varying the pressure of the gas above the liquid in the chamber 11 so that the liquid level in the chamber can be varied independently of that in the boiler to test operation of the float and switch. As shown an air pump can be connected at 20 to a conduit 19 and can be used, when the valve 21 is opened, to increase the gas pressure to simulate a low liquid level. In modifications, Fig. 3 and 4 (not shown) the valves 15 and 21 may be combined in a single changeover valve device (30) and the air pump replaced by a pump (40) for supplying steam from the boiler. A high liquid level can be simulated by using valve 21 to vent the float chamber or by using a pump to reduce the gas-pressure in the float chamber.
