Abstract
The invention relates to a floating ball liquid-level meter, in particular to an intelligent dual-display explosion-proof floating ball liquid-level meter which solves the problems of low measuring accuracy and poor stability of an existing floating ball liquid-level meter due to the fact that liquid is measured in a contact manner. One end of a floating ball connecting rod is connected with a floating ball, the other end of the floating ball connecting rod is connected with a gear set, an optical grating sensor is arranged on a flange base, a flange is fixed on the flange base, an optical grating and an instrument panel are fixed on a concentric shaft, the concentric shaft penetrates the flange base to be connected with the gear set, and the gear set drives the concentric shaft to rotate. Liquid-level height is read according to a reading of a mechanical pointer on the instrument panel; meanwhile, the optical grating sensor receives optical signals of the optical grating, converts the optical signals into electric signals and transmits the electric signals to a circuit board, the circuit board performs amplification operation on the received electric signals, and data obtained after operation are displayed on a liquid crystal display. By the application of a non-contact sensing technology, accuracy and stability of liquid-level measurement are improved.
