Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are to explain rather than limit the present invention.
[0039] see Figure 1-7 , a static level with dual sensitive sensors, including two levels with the same structure, namely a reference level 19 and a measuring point level 20; the level includes a tank 2 with an opening at the top, a liquid level sensor 1, and a bubble level 6 , buoy 4 and base.
[0040] see figure 2 , the tank 2 is set on the top of the base, the bubble level 6 is set on the base and is located on one side of the tank 2, the tank 2 is filled with liquid, the buoy 4 is set in the tank 2, and the top of the tank 2 is set There is a top cover, the liquid level sensor 1 is arranged on the top surface of the top cover, the top of the buoy 4 is provided with a buoy measuring rod 3, and the upper end of the buoy measuring rod 3 is connected to the liquid level sensor 1 through the top ...

The invention discloses a static level provided with double sensitive sensors and a measurement method of the static level. According to each level body, a tank is installed on a bases, and meanwhilea bubble level is installed on the base; the liquid level in the tank is regulated to be horizontal through the bubble level, and the situation that a liquid level area change influences measurement precision is avoided; further, a flowmeter is installed on the base, and the flow of liquid is determined through the flowmeter; meanwhile, one liquid level sensor is arranged at the top of the tank, and the liquid level sensor is connected with a buoy in the tank; and when the liquid flows, rise or drop of a measuring point can be obtained just by observing data of the liquid level sensor, and then the rise or drop height of the liquid level is calculated through parameters of the flowmeter. According to the static level provided with the double sensitive sensors, each tank is horizontally placed, so that a measurement error is reduced; and the change height of the liquid level can be accurately calculated through each flowmeter, so that the measurement precision is improved.
Description
technical field [0001] The invention relates to the technical field of monitoring equipment for building settlement, in particular to a static level with dual sensitive sensors and a measurement method thereof, which are suitable for settlement monitoring of bridges, dams, tunnels, houses and other buildings. Background technique [0002] Construction on the ground, such as buildings, bridges, dams, etc., will cause foundation settlement. At present, static level is the main equipment for monitoring such settlement. At present, most of the static level gauges use the principle of the communicating device. By measuring the change of the liquid level, the position change of the two points can be obtained, and then the differential settlement of the two can be obtained. Nowadays, such sensors basically have some common shortcomings, which are easily affected by the external environment and affect their use effect. [0003] Most of the existing static level gauges use the rise ...
