, Overview The bubble water level meter is a high-precision water level sensor independently developed and produced by Kehao Company. The compressed air generated by the piston pump flows through the measuring tube and bubble chamber and enters the water body to be measured. The static pressure in the measuring tube is proportional to the water level in the bubble chamber. The bubble water level gauge successively measures the atmospheric pressure and bubble pressure, takes the difference between the two signals, and calculates the water level height above the bubble chamber. The bubble water level meter has the characteristics of high precision, high reliability, high intelligence, no need for gas bottles, no well logging, no maintenance, anti-vibration, and long life. It is especially suitable for flowing water bodies, large, medium and small rivers, reservoirs, or water bodies with serious pollution and Corrosive industrial wastewater and other situations where it is inconvenient or expensive to build logging wells, such as monitoring of water conservancy and hydrology, upstream and downstream of dams, oceans, groundwater, petroleum, chemical industry, sewage treatment plants, urban drainage pumping stations, etc.
, Functional features: The crank connecting rod piston pump is used as the air blowing and pressure-inducing device. It has a zero-point automatic correction function, which can completely eliminate the zero-point drift error. Through an external temperature sensor, it can effectively compensate for the influence of temperature changes on the specific gravity of the liquid. It has analog output and Digital communication interface, user-friendly wide voltage design, with reverse connection protection, overvoltage and overcurrent protection and lightning surge absorption capability. Configuration display and input keyboard. It has on-site configuration function. Parameters can be configured through the keyboard. The display should display information including It is limited to automatic cleaning functions such as latitude, temperature compensation, base altitude, base water depth, baud rate, address, etc. to ensure that the air pipe is unobstructed and can store no less than 1 measurement record in a cycle. It also has the function of controlling air pumping.
