I. Role of PQWT Ground Pipeline Locator
PQWT Ground Pipeline Locator is a kind of instrument used for detecting the position, direction, depth and the position and size of the corrosion protection layer breakage point of underground metal pipelines, cables and so on. It is widely used in water companies, gas companies, railway communications, industrial and mining, infrastructure units, etc. It is one of the necessary tools for underground pipeline renovation, maintenance and census.
Second, PQWT Ground Pipeline Locator need to have the function of
PQWT Ground Pipeline Locator needs to have the following functions:
1. Be able to quickly and accurately detect the location, direction, depth and the position and size of the corrosion-resistant layer of the steel pipeline damage point of the underground water pipeline, metal pipeline, cable and so on.
2. With signal strength indication, left and right arrow indication, compass direction indication and other functions, it is convenient for users to judge the position and direction of underground pipelines.
3. Capable of automatic depth measurement, automatically displaying the true depth of the target pipeline when the instrument is placed above the pipeline.
4. With automatic prompting of the 70% bathymetry method, 70% of the signal points can be easily determined through graphics and prompting sound.
The working principle of PQWT Ground Pipeline Locator and the use conditions of the instrument.
The working principle of PQWT Ground Pipeline Locator is mainly electromagnetic induction method and electromagnetic wave method. Among them, the electromagnetic induction method utilizes the reflection principle and electromagnetic induction principle of electromagnetic wave in the transmission process, generates electromagnetic wave by sending signal source, and receives electromagnetic wave signals induced by underground metal pipeline to determine the location and depth of underground pipeline. The electromagnetic wave method utilizes the transmission characteristics of electromagnetic waves in underground metal pipelines to determine the location and direction of underground pipelines through changes in the strength of the received electromagnetic wave signals.
When using PQWT Ground Pipeline Locator, the following conditions should be noted:
1. The signal source is capable of generating enough electrical energy to create an electric current in the line that transmits the electrical energy and generate a magnetic field around it.
2. Able to receive and process the process of magnetic field changes and display them in the form of electrical signals.
3. Have a certain anti-interference ability to avoid other electromagnetic wave interference.
IV. Basic Functions of PQWT Ground Pipeline Locator
The basic functions of PQWT Ground Pipeline Locator include:
1. Quickly and effectively determine the direction and depth of underground metal pipelines.
2. With signal strength indication, left and right arrow indication, compass direction indication and other functions.
3. Detecting pipelines up to a maximum depth of 20 meters.
4. Automatic depth measurement, when the instrument is placed above the pipeline, it automatically displays the true depth of the target pipeline.
5. 70% depth measurement method with automatic prompts, 70% signal points can be easily determined through graphics and prompts.
