Description

Technical Field

[0002] The water level probe is an analytical instrument used to detect the water level of a boiler or water tank. Commonly used water level probes include coffee machine water level probes, boiler water level probes, and water tank water level probes. In boilers and other equipment, water vaporizes at high temperatures, and the consumption of water and steam is large. Water must be continuously replenished to keep the water in the container at a certain height. The purpose of the water level probe is to detect the height of the water level and keep track of the water level in the container at any time. The probe-type water level sensor uses the electrical conductivity of the material to measure high and low liquid levels, and can also be used for liquids with weak conductivity and wet solids.
