DEVICE FOR MEASURING ANGLES OF LIST AND TRIM OF WATERCRAFT IN SWELL Russian patent published in 2006 - IPC B63B39/14 

FIELD: shipbuilding; devices for measuring angles of list and trim of watercraft under any operating conditions.

SUBSTANCE: proposed device consists of communicating vessels made in form of sections of tubular circular passage formed by rotation of contour of flat figure around axis lying in plane of this figure but not intersecting it; said communicating vessels are communicated in their upper and lower parts and are partially filled with conducting fluid in area of level of horizontal plane coinciding with axis around which circular passage is formed. Vessels have constant cross-section in length and symmetrical shape of contour of flat figure relative to axes of symmetry, circle for example. Device is provided with restrictor, angle sensor, electronic transducer and dial. Sensor is formed by sections of tubular circular passage made from conducting material; their inner surface is coated with nonwettable dielectric with conducting fluid above it which is immiscible with dielectric fluid fully filling the hermetic space above conducting fluid. Sections of tubular circular passage are communicated in their upper parts through restrictor; electronic transducer is electrically connected with each conducting sections of tubular circular passage and with conducting fluid.

EFFECT: improved service characteristics of device.
