Differential pressure water level measuring system

Abstract

The invention discloses a differential pressure water level measuring system which comprises a pressure sensor and an air pipe. An end of the air pipe is connected with the pressure sensor, a plurality of temperature sensors are arranged on the inner side walls of the air pipe at preset intervals and are used for acquiring temperature values of corresponding locations where the various temperaturesensors are positioned in water, and transmitting temperature signals corresponding to the acquired temperature values to a central processing unit, and the various temperature signals and pressure signals acquired by the pressure sensor are computed by the central processing unit to obtain current water levels. The differential pressure water level measuring system has the obvious advantages that the temperature sensors are arranged in a water body at the preset intervals, accordingly, the temperatures of the different locations of the water body can be acquired and can be integrated with one another, the current water levels can be computed, the problem of low water level measurement precision due to the fact that only the temperature of a specific location in an existing water body isacquired can be solved, and the accuracy of water level measurement can be improved.

Description

technical field [0001] The invention relates to the field of water environment, in particular to a differential pressure water level measurement system. Background technique [0002] In recent years, with the continuous exploitation of underground resources, many ecological and environmental problems have been caused. Therefore, it is imminent to strengthen the monitoring of groundwater. [0003] Traditional groundwater monitoring mainly uses the differential pressure water level gauge to calculate the water level height. Among them, the differential pressure water level gauge uses a trachea to introduce air into the sensor to calculate the water level height by measuring the difference between the pressure under the water and the air pressure on the water surface, and the actual height of the water level Closely related to water temperature, water temperature affects the density of water, which indirectly affects the accuracy of actual water level measurement. The traditio...
