Document Type and Number:
WIPO Patent Application WO/2010/015132
Kind Code:
A1
Abstract:
A servo liquid level meter comprises a float (1). Measuring elements such as a temperature sensor (9), a pressure sensor (10) and an interface sensor (11) are fixed on the float (1); a contact (2) provided on the shell body of the float (1) is connected with a working circuit provided in the float (1). When the float (1) is moved up and down, the contact (2) is enabled to contact or cut off a contact electrode (3). When the contact electrode (3) is in contact with the contact (2), a main-board of the liquid level meter detects the voltage of a power supply circuit in the float (1) through the contact (2), and thereby charges the power supply circuit in the float (1) according to the detected result, and moreover, the working circuit can exchange information with exterior through the contact (2) and the contact electrode (3).
