Problems solved by technology

[0003] However, the accuracy of the experiment is not enough, water droplets hang on the wall, and the liquid level is not equal, which will lead to measurement errors
The actual water level cannot be measured accurately, and the water level can only be deduced from the output of the air pressure sensor
Moreover, if the water level needs to be measured repeatedly, the water in the U-shaped tube needs to be released repeatedly, which is very inconvenient

Abstract

A water level measuring device comprises a fixed water trough, an air pressure sensor, a movable water trough and a lifting supporting device.The opening end of the fixed water trough is sealed in one end of an air pipe.The air pressure sensor is connected with the other end of the air pipe.The movable water trough can perpendicularly move and is communication with the fixed water trough through a water pipe.The lifting supporting device is used for controlling the movable water trough to move perpendicularly and also used for supporting the movable water trough to be located at any position in the perpendicular moving direction.The water level height of the movable water trough is precisely controlled through the lifting supporting device, air pressure changes are measured through the air pressure sensor, and thus the water level is measured.The actual height of the water level is read through a scale ruler, and then the actual height of the water level is compared with a numerical value measured through the sensor.The device is precise in measurement, convenient to carry, easy to demount, control and use and capable of being applied to teaching, scientific research and various laboratory tests.

Description

technical field [0001] The invention relates to a measuring device, and further relates to a water level measuring device and a method for measuring water level using the measuring device. Background technique [0002] Such as figure 1 As shown, a general water level measuring device uses a U-shaped tube and an air pressure sensor. When using, first open both ends of the U-shaped tube and add a small amount of water to balance the water levels on both sides. Then one end is sealed into the trachea, and the other end of the trachea is connected to the air pressure sensor. Then, add water to the other end of the U-shaped tube, the liquid level of the water rises, and a water level difference occurs. This is because the gas at the end connected to the air pressure sensor is compressed, and the air pressure sensor outputs the air pressure value, thereby inferring the height of the water level change. [0003] However, the accuracy of the experiment is not enough, water drople...
