Description

Auxiliary device of water level meter

Technical Field

The utility model belongs to the technical field of water level meter measurement, and in particular relates to an auxiliary device of a water level meter.

Background Art

Water level meters are widely used for water level measurement in water conservancy projects, hydrology and geography, environmental protection, industry and agriculture, etc., such as the measurement of groundwater level and well water level in rural irrigation areas, reservoir dams, river levees, power stations, etc.

The water level meter consists of a probe part, a cable part, and a receiving system. A water resistance contact point is installed inside the probe part. When the contact point touches the water surface, the receiving system will be connected. When the contact point leaves the water surface, the receiving system will be closed. The cable part is a cable with a scale, which makes measurement and reading more convenient and accurate. The receiving system consists of a sounder, an indicator light, and a peak indicator. The sounder emits a continuous buzzing sound when it encounters water, the indicator light is on, and the peak indication is the voltage meter indication.

The defects of the existing water level meter technology: 1. Directly using the water level meter to measure the water level may cause false alarms due to contact with the wet well wall or muddy water, thus failing to correctly determine the water level height; 2. The existing water level meter probe has no guide and is easily suspended in front of the well wall steps or obstacles and cannot be lowered to the bottom of the hole; 3. The existing water level meter probes are relatively light and cannot pass through the hole if there is a slight obstruction; 4. When water is poured from above or the water flow is large, the measured water level is not the actual water level. Therefore, an auxiliary device for the water level meter is needed to solve this problem.
