Example Embodiment

[0034] Example 1:

[0035] This embodiment is a high-precision vibrating wire water level gauge with automatic compensation, and its main structure is as follows image 3 Shown.

[0036] Reference image 3 , The high-precision vibrating wire water level gauge with automatic compensation in this embodiment is mainly composed of sensitive parts 1, protective cylinder 2, intelligent compensation output parts 3, float parts 4, sensitive parts mounting and fixing parts 5 and instrument integral mounting and fixing parts 6 composition. The sensitive component 1 is freely hung inside the protective cylinder 2 through the universal joint of the sensitive component mounting and fixing component 5, and the intelligent compensation output component 3 is located on the upper part of the protective cylinder 2 and fixed with it. The float component 4 is connected to the sensitive The components 1 are connected together and hung inside the protective cylinder 2. The integral installation and fi...

Abstract

The invention discloses a vibrating wire type water level indicator with a self-compensation function, and belongs to the technical fields of hydraulics, hydrology and engineering monitoring. A wholesensitive component forms a completely sealed and integrated structure and is vacuum in the interior. External disturbance is avoided, and a long-term and stable testing value is guaranteed; meanwhile, an air pressure sensor and a temperature sensor are installed in a water level indicator shell body in a sealed mode, data collection is performed through an intelligent compensation output unit, the data are calculated to obtain a high-accuracy water level testing value, and the water level value is directly outputted, on-site conversion is not needed, and the testing value is more intuitive. The vibrating wire type water level indicator with the self-compensation function changes the structure and sealed installation technology of the existing water level indicator, solves the problem thatthe existing water level indicator cannot simultaneously consider two aspects of long-term, stable and reliable waterproof sealing and obtaining the high-accuracy testing value.

Description

technical field [0001] The invention belongs to the technical field of water conservancy, hydrology and engineering monitoring, in particular to a vibrating wire water level gauge with automatic compensation. Background technique [0002] The high-precision vibrating wire water level gauge is mainly used to monitor the seepage of dams, and can be used in other places with high-precision water level or liquid level measurement. At the same time, it can also be used for settlement measurement of subways, bridges, buildings, etc. Wide range, it is one of the commonly used sensors in engineering construction. However, based on its measurement principle and often installed in the field environment, it is often faced with long-term use in harsh environments with high humidity, large temperature difference between day and night, and obvious changes in air pressure throughout the year, which seriously affect the accuracy of the instrument's measurement value or service life. The st...
