The electronic water gauge uses a digital sensor and uses the weak conductivity of water to measure the water level of the electrode to obtain data. The water gauge section adopts the electrode contact measurement method. The error will not be affected by environmental factors and only depends on the electrode spacing. It can automatically detect the water level for a long time. It is used for water level monitoring in rivers, lakes, reservoirs, urban road waterlogging and other scenes.
