Abstract

A modular electrode water belongs to the technical field of manufacture of measuring equipment and comprises a gauge body, 74HC165 integrated chip, pull-up resistors Ru, a single-chip microcomputer, and a display; the front of the gauge body is fitted with an outer cover panel, the chip is fixed in the gauge body, each output end is connected to one pull-up resistor Ru, the output end of the chip is connected to the single-chip microcomputer, a measuring point P is made between the chip and each pull-up resistor Ru, the measuring points P are fixed to the back of the chip sequentially from top to bottom, and a wave stabilizing cavity is formed between the back of the chip and the outer cover panel. In operation, when water level is below the points P, the measuring points P are at high level; when the water level reaches the measuring points P, the measuring points P are at low level. High-precision digital measurement is provided for water level, the measurement is insusceptible to the changes in ambient temperature, humidity, noise and altitude height, the nonlinear distortion problem can be eliminated, and the data are reliable.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment manufacturing, and relates to a water gauge. Background technique [0002] The traditional water gauge is a vertical ruler fixedly installed on the dam body of the water river, which can only roughly show the height of the water level. At present, the most accurate water level gauge is the laser water level measuring instrument. Since there is usually water vapor on the water surface, the light will be refracted and the measurement results will be affected. Contents of the invention [0003] The technical problem to be solved by the invention is to disclose a modular electrode water gauge with simple structure and accurate measurement. [0004] The solution of the present invention to solve the technical problem is to use the ruler body, 74HC165 integrated chip, pull-up resistor Ru, single-chip microcomputer and display to form a modular electrode water level gauge. The chip is fix...
