Abstract (en)
[origin: EP0854035A1] The method uses a mixing vessel (7) for the ink (2) which is introduced through a tube (9) passing to a measuring chamber (8) via valve (10). Within the chamber is a temperature sensor (12) and an ultra sonic generator /sensor (13). The composition of the ink is based upon the sound velocity transmission measured by the ultra sonic device. A vent valve (14) controlled by a microprocessor or computer regulates the transfer of ink into the vessel
