IPC: G01F25/00
Filed: 1990-02-13
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>

Abstract: Oil level regulator for internal combustion engine (1) comprising a level detector fitted to an enclosed separate measuring chamber (7) which is in communication with the engine sump (12). 
     A remote controllable shut-off device (6) can allow flow of topping-up oil from a fresh-oil tank (5) to the sump (12). 
     An electronic control device (8) is programmed to check the oil level before the engine is started, in a first position of the ignition-starting switch (4) of the engine and allows starting when the level is found to be "correct". 
     It first meters a predetermined oil volume into the sump (12) by energising the shut-off device (6) when the level is "too low", and frees the starting procedure when the level has become "correct". 
     The program may include a second topping-up in the first switch-position, and, if still "too low", an alarm signal. 
     It is preferred to use a gear-pump as shutt-off device (6), making the topping-up volume less sensitive to viscosity and allowing the fresh-oil tank (5) to be positioned anywhere with regard to the level in the sump.
