Capacitive induction type electronic water gauge and working method thereof

Abstract

The invention discloses a capacitive sensing type electronic water gauge and a working method thereof in the field of electronic water gauges.The capacitive sensing type electronic water gauge comprises a stainless steel measuring body shell, a measuring body is arranged in the stainless steel measuring body shell, the measuring body is of a long-strip-shaped structure, a plurality of capacitive probes are evenly distributed on the measuring body, a plurality of sensor chips are arranged on one side of each capacitive probe, and the sensor chips are arranged on the other side of each capacitive probe. And the top end of the measuring body penetrates through the top end of the stainless steel measuring body shell. According to the invention, the measuring body, the sensor chip, the capacitive probe and the electronic circuit module are fixed in the stainless steel measuring body shell through glue sealing by adopting the epoxy sealing body, so that the measuring body, the sensor chip, the capacitive probe and the electronic circuit module can be firmly fixed; and moreover, the circuit connection insulativity of the measuring body, the sensor chip, the capacitive probe and the electronic circuit module can be ensured, the effect is excellent, and the service life can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of electronic water gauges, in particular to a capacitance-sensing electronic water gauge and a working method thereof. Background technique [0002] Hydrological observation is a task of collecting data related to water bodies. It is based on the observation of various hydrological elements of rivers, lakes, and seas. The hydrological elements of rivers and lakes include water depth, water level, flow direction, flow velocity, flow rate, water temperature, Ice regime, specific gravity, sand content, precipitation, evaporation, water color, transparency, chemical composition of water, etc.; ocean hydrological elements include tides, currents, waves, currents, sea temperature, salinity, sea air temperature, air pressure, wind direction, Wind speed, plankton, etc. Usually, according to certain conditions, hydrological observation stations are set up at certain locations or cross-sections of rivers, lakes, and seas to c...

AI Technical Summary

Problems solved by technology

Usually, according to certain conditions, hydrological observation stations are set up at certain locations or cross-sections of rivers, lakes, and seas to conduct long-term uninterrupted hydrological observations. Bed, river bed, river bank change, ocean current, runoff law, and important data for various water conservancy projects, coastal engineering design calculations, and compilation of navigation guides. In the process of hydrological observation, water gauges are needed, but the existing water gauges are in When in use, most of the detection components inside the water gauge are sealed by the sealing components on the casing, the sealing effect is poor, and the service life of the guide is reduced. At the same time, most of the external seals are crimped and fixed by screws, and the installation and removal efficiency is extremely low. Data collection is more inconvenient
