Integrated arrangement is carried out with graduation mark, realizes the measurement to well depth and water level, but there is also measurement process needs for the device
Artificial unwrapping wire, the defect of time and effort consuming.To the measurement of inductance of level of ground water, at present mainly include the following types: Chinese patent
CN108344467A " a kind of field one fluid measurement device of well depth water level and its measurement method ", is transferred to using cable toward underground
After one radiological unit of the water surface, buried by the distance that hand-held instrument emits wireless signal the measurement water surface to well head with obtaining water level
Deep data efficiently solve the problems, such as that measurement of inductance error is larger, but the program can only measure depth to water and not be capable of measuring well depth,
There is also need cable to assist decentralization reflection unit, relatively time-consuming effort simultaneously.A kind of Chinese patent CN104060984A " monitoring
The radio frequency admittance device and method of water supply well deep water level " is visited using the radio frequency admittance sensor being mounted on water outlet line pipe wall
Head and the radio frequency admittance transmitter terminal box being mounted on the water outlet underwater flange disk of water supply well wellhead ground, radio frequency admittance sensing
Device probe, by cable connection, is converted into water level signal using radiofrequency signal, realizes water level with radio frequency admittance transmitter terminal box
Measurement.The device performance is reliable, measurement water level range is big, and error is small, but installation is complex, and cannot measure well simultaneously
It is deep.Chinese patent CN206876263U " a kind of ultrasonic water level gauge ", by the way that using the measurement outer tube being placed in well, measurement is outer
Venthole is set on pipe, a floating ball that can be floated up and down with water level is set in measurement outer tube, is embedded at the top of measurement outer tube super
Acoustic measurement component utilizes ultrasonic measurement water level depth.Program precision is higher, but needing to install in well specially sets
Standby, measurement cost is high, and cannot measure well depth data simultaneously.A kind of Chinese patent CN207036216U " CW/FM continuous wave/frequency modulated modulated thunder
Up to water-level gauge ", it using continuous frequency modulation radar modulation system, realizes the measurement of water level in the case of wide range, big variability, there is essence
The features such as degree is high, stability is high, low in energy consumption, strong anti-interference ability and repeatability are strong, but well depth data cannot be measured simultaneously.
