<p>To overcome problems due to interaction between the electrical contacts and the liquid, the air gap (28) of the angular movement sensor (11) is a wall of insulating material which sealedly separates the space containing the linkage (10) and the rotor (23) of the angular movement sensor (11) from that containing the stator (24) of the angular movement sensor (11) and the relative circuit which processes the level data and displays the result. In addition, to prevent any deformity of the tank in which the device is installed from being able to influence the measurement, the shaft (14) and cylindrical casing (9) may be telescopic. The base of the cylindrical casing and the base of the tank are therefore always in contact. <IMAGE></p> |
