Water level measuring device

Abstract

The invention discloses a water level measuring device which comprises a box body, wherein a controller is arranged inside the box body; the controller is connected with a display; a measuring rope scroll is further arranged inside the box body; one end of a measuring rope is wound on the measuring rope scroll; the measuring rope scroll is connected with the controller; the other end of the measuring rope is connected with a pressure sensor inside a detecting head outside the box body in a mode of surrounding a pulley; the detecting head is dropped into water to be measured; and water pressure data are fed back to the controller by the pressure sensor through leads inside the measuring rope, and are processed by the controller and subsequently displayed on the display. A water level can be read directly from the display; and thus, the water level measuring device has the characteristics of being convenient to carry, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a water level measuring device. Background technique [0002] At present, most of the groundwater temperature and water level monitoring equipment are imported instruments, most of which rely on composite sensor probes to obtain water level and temperature signals, and then transmit the signals to the instrument host through cables for processing, and obtain the measured values ​​and store them in the host chip. . Its existing problems and shortcomings: 1) It is expensive and not suitable for domestic promotion and use. 2) The water level measurement range is short, so it cannot be applied to the monitoring of deep groundwater. 3) It is necessary to download the measured value to the computer to read it. Therefore, it is necessary to carry the computer to read the data on site, and it cannot work for a long time due to the limited battery power of the computer. 4) The volume of the main engine is large, and it is necessary t...

Problems solved by technology

Its existing problems and shortcomings: l) Expensive, not suitable for domestic promotion and use

2) The water level measurement range is short, so it cannot be applied to the monitoring of deep groundwater

3) It is necessary to download the measured value to the computer to read it, so it is necessary to carry the computer to read the data on site, and it cannot work for a long time due to the limited battery power of the computer

4) The volume of the main engine is large, and it is necessary to build houses and other buildings on site to protect the main engine, which increases the installation cost; the main engine is placed outside the wellhead. The stability of components is affected, resulting in an increase in the failure rate of the instrument
