The invention discloses a water level measurement device, comprising a shell (1), a measurement and control unit (2), a resistance guide rail (3) and a floating ball (4), wherein the floating ball (4) is in contact with the resistance guide rail (3) through a roller (6); the resistance guide rail (3) is of a groove type structure in which an airtight cavity (30) is embedded; the airtight cavity (30) is made of soft insulation material, and a first electric conductor (31) and a second electric conductor (32) are arranged in parallel in the airtight cavity (30); the first electric conductor (31) and the second electric conductor (32) are oppositely pasted on the inner wall of the airtight cavity (30), and the upper ends of the first electric conductor (31) and the second electric conductor (32) are connected with the measurement and control unit (2); and the roller (6) squeezes the airtight cavity (30), so that the first electric conductor (31) and the second electric conductor (32) are electrically conducted at a squeezing point. The water level measurement device provided by the invention measures the water level according to the variation of resistance, and is simple in device and low in price; and the first electric conductor and the second electric conductor are sealed in the airtight cavity, is free of erosion of water, the contact resistance is invariable, and the measurement accuracy is high.
Description
technical field [0001] The invention relates to a liquid level measuring device, in particular to a water level measuring device, which belongs to the technical field of liquid level measurement. Background technique [0002] Water level measurement is widely used in various industries, mainly in open channels, reservoirs, hydropower stations, ship locks, pumping stations and other water conservancy, hydropower, and hydrological outdoor occasions. [0003] At present, there are four main water level sensing methods for water level measurement in outdoor occasions: floating ball coded sensor, input liquid level transmitter, ultrasonic liquid level transmitter, and radar liquid level transmitter. [0004] The floating ball encoder sensor uses the rotation between the floating ball hanging on the runner and the weight to map the change of the water level to the code value of the encoder coaxial with the hanging wheel, so as to measure the corresponding water level. This measur...
