The invention provides an electrolyte density measuring device. A circuit board is arranged on the upper portion of a liquid storage tank filled with electrolyte, a first gas pressure sensor, a second gas pressure sensor and a temperature sensor are connected to the circuit board, a temperature sensing resistor is arranged between the temperature sensor and liquid, and a first gas guide tube and a second gas guide tube are inserted into the liquid storage tank. The upper ends of the first gas-guide tube and the second gas-guide tube are respectively connected with the first gas pressure sensor and the second gas pressure sensor in a sealing manner, a parallel area and a vertical area are arranged between the first gas-guide tube and the second gas-guide tube, the two gas-guide tubes are parallel to each other and vertically immersed into the electrolyte, and the height difference of the gas-guide tubes is a constant value and is fixed in the liquid storage tank. Due to the fact that the L-shaped gas-guide tube is provided with the vertical area and the parallel area, liquid compresses the gas column in the parallel area firstly, the liquid in the gas-guide tube is controlled not to enter the vertical area, the height difference of the gas-guide tube is constant to be the liquid level difference, and the measurement accuracy is guaranteed. The device is suitable for being used as an electrolyte density measuring device.
Description
technical field [0001] The invention proposes a measurement device in the field of metering, which is mainly used in the measurement of the density of battery electrolyte. Specifically, it is an electrolyte density measuring device. Background technique [0002] At present, the density measurement of battery electrolyte is based on the principle of liquid pressure. Usually, two air pressure sensors measure the pressure difference, and the air pressure sensors are respectively connected to the air guide tubes standing upright in the electrolyte, and the liquid level difference of the air guide tubes is set to a fixed value, and the density value of the liquid can be obtained according to the pressure formula. [0003] However, when measuring, the air column in the airway will shrink differently due to different pressures. The two airway tubes are not at the same liquid level, and the pressures are inconsistent. Therefore, the liquids entering the airway tubes are also differ...
