Installation to monitor water level in a boiler

Abstract

Abstract The installation (10) comprises a housing (11) which is situated in the water reservoir (3) of a boiler (1) and has at least one lower and one upper passage opening (16, 17). To detect the water level, there are arranged in the housing (11) at different levels a number of water-sensitive sensors or water-level electrodes (12-14) which are connected to a control (5). According to the invention, there is also provided a take-off in the form of an extraction pipe (20) which allows a take-off of the water situated in the housing (11) into a chamber situated outside the boiler (1) until the sensor (14) positioned at the lowest point is exposed. To open or close the take-off, the extraction pipe (20) is connected to a shut-off valve (21). By opening the shut-off valve (21), the water level B inside the installation (10), in comparison with the water level A of the boiler (1), can be lowered quickly and subsequently the functioning of the water-level electrodes (12-14) can be checked. <IMAGE>
