Accumulator with both direct and remote quantity level indication
摘要:
An apparatus for determining the fluid level of a container, such as an accumulator, may include both a remote quantity indicator and a direct quantity indicator. The remote quantity indicator may include a remote dial at the end of a flexible cable or an electrical signal receiver receiving an electrical signal from a rotary variable differential transformer (RVDT), such as a potentiometer. The RVDT type of indicator may include an electrical connector on the accumulator to attach an electrical cable to carry the quantity level signal. The direct quantity indicator may include a dial directly mounted on the accumulator. The remote/direct quantity indicators may include, for example, one of the following three combinations: 1) a dial directly on the accumulator and a remote dial at the end of a flexible cable; 2) an RVDT output and a dial directly on the accumulator; and 3) an RVDT output on an accumulator, a remote dial at the end of a flexible cable and a dial directly on the accumulator.
