ABSTRACT:
A method and apparatus for the continuous automatic measuring of the filterability threshold temperature of a liquid such as a doped diesel oil comprising passing the doped diesel oil through a measuring circuit surrounded by a cooling liquid at a constant flow rate, providing a crystal retaining means beyond the cooled part of said measuring circuit, measuring the pressure differential before and immediately after said crystal retaining means, and providing resistance heating to said measuring circuit when the measured pressure differential exceeds a predetermined value and continuously measuring the temperature of said liquid immediately down stream of said crystal retaining means. The switch of the device is actuated in response to the pressure differential increasing beyond a predetermined level which is caused by a build-up of microcrystals, for turning on the resistance heating circuit and melting the microcrystals. The heating circuit is then automatically turned off when all the microcrystals have melted, by the corresponding decrease in pressure differential in the measuring circuit in response to which the device actuates the switch once again back to its initial position.
