Abstract:
A position indicator for a submerged valve, said valve forming part of a main hydraulic system for transfer of fluids, the position indicator comprisinga pressure signal generating means for generating a pressure signal being indicative of a position of the valve; said pressure signal being convertible into an indication being displayable on a visualization screen; wherein said pressure signal generating means comprises at least one hydraulic cartridge; a pressure signal transmitting means for transmitting the pressure signal over long distances; a mechanical means for detecting the position of the valve; whereinsaid mechanical means comprises at least one cam fixedly positioned on a rotating actuator shaft of the valve for acting upon the pressure signal generating means upon rotation of the rotating actuator shaft which actuates the valve, the mechanical means converting a circular motion of the actuator shaft into a rectilinear motion of a part of the pressure signal generating means, thereby generating the pressure signal indicative of a position of the valve.
