Photoelectric indicating instrument for oil dip rod

The utility model relates to a photoelectric indicating instrument for an oil dip rod, which can not only solve the problems that, when a storage tank in the petroleum industry uses an ammeter to detect water level, the operation is inconvenient, the thickness of an oil-water mixed layer can not be measured and recorded, the detection current is high and the potential safety hazard exists, but also facilitate the operation at night by mounting a lighting lamp on the instrument. The instrument comprises an instrument housing, an amperemeter, a leading wire clip, a fixed clip, a power supply, a detection circuit and a lighting branch circuit, wherein the instrument housing is fixed on an oil dip rod frame through the fixed clip, the power supply, the detection circuit and the lighting branch circuit are mounted in the instrument housing, the power supply is used for power supply for the detection circuit and the lighting branch circuit, a positive pole of the circuit is connected with the oil dip rod frame, the
