GL18-LVR9 Acoustic Line Locator for PE(Polyethylene) Gas Pipeline

Overview

GL18-LVR9 is a highly advanced, compact, and lightweight gas PE pipeline acoustic wave locator. It is an exquisite, durable, and fashionable device that enables locating polyethylene pipes in underground gas distribution lines. The product boasts excellent performance, high-quality manufacturing, and a superior user experience. Its design focuses on enhancing work efficiency and improving practicality and durability while ensuring portability. Developed by Xi'an Quick Detection Instrument Company, Ltd, GL18-LVR9 is a significant milestone product resulting from years of research and development and manufacturing experience in acoustic pipeline detection instruments.

Working Principle

The GL18-LVR9 gas vibrator is a device used to locate acoustic waves in gas pipelines. It is connected to the pipeline by clicking with the pipeline release valve. The transmitter supplies power to the gas vibrator and controls the signal output, which generates a particular frequency vibration signal when it drives the gas vibration in the pipeline. This vibration signal is transmitted horizontally along the gas flow in both directions and vertically to the ground. The LVR9 receiver acquires the signal through the ground sensor and transmits it to the host. The host then filters and algorithmically processes this signal to identify and locate the strongest ground signal directly above the buried pipeline. The operator can then listen to the effective signal through the headphone for judgment and positioning.

Transmitter GL18

● The design of the transmitter takes into account the requirements of practicality and portability. As a result, it is smaller, lighter, and more durable.

● The transmitter has a wireless remote control function that allows for remote control of the on/off switch, frequency, and power adjustment of the transmitter within a range of 3 kilometers. The remote control also provides the ability to remotely monitor the status of the transmitter.

● The transmitter panel features a temperature display function, which allows for safe operation of the instrument by indicating the internal temperature of the gas vibrator.

● The transmitter can adjust the frequency within a range of 100Hz-999.99Hz with an accuracy of 0.01Hz.

● The transmitter comes with a LORA module that enables remote control of the transmitter. This feature improves work efficiency, reduces commuting costs, and ensures that the transmitter can be remotely controlled within a range of kilometers. The LORA module is easy to pair, and the instrument can be automatically connected after powering on. The transmitter can be remotely switched on and off, and frequency and power adjustment can be done via the matching LVR9 receiver (optional).

● The transmitter has a variety of transmission frequencies and modes to ensure that it can cope easily with different environments. It has multiple gears for adjusting the output power, and there is no blind spot detection at short, medium and long distances. The combination of multi-frequency, multi-mode, and multi-power ensures accuracy, detection distance, and better detection results.

● The transmitter has a built-in vibrator temperature measurement function that displays the temperature of the vibrator and warns of normal temperature and temperature overrun.

● The transmitter has a built-in ultra-large capacity battery that has a continuous 12-hour ultra-long standby function.

● The transmitter has more output power, which enables it to transmit stronger signals and achieve deeper and farther detection.

● The specially modulated frequency of the transmitter greatly improves the instrument's signal recognition in noisy environments.

Receiver LVR9 

● The LVR9 receiver adds a built-in remote control function, which embeds the remote control and antenna of the previous generation into the LVR9 housing, which can more conveniently control the transmitter's start and stop, frequency power adjustment, etc., through the LVR9 receiver. There is no need to carry a remote control.

● The LVR9 receiver adds a built-in GNSS positioning module, which can directly display the latitude and longitude coordinates of the current location.

● LVR9 also adds a jack dust cap, which can prevent dust and moisture from entering the instrument and damaging the instrument when the instrument is not in use.

● The LVR9 has been designed with ergonomics in mind, making it easy to work efficiently and efficiently. The grip of the curved bottom shell of the shell, the soft overlock design of the upper shell of the shell, the dual-purpose knob for rotary pressing, the one-handed grip of the probe sheath, the integrated base design of the probe, the quick installation and disassembly of the probe, and the telescopic strap all reflect ergonomics and convenient and efficient operation.

● The LVR9 adopts the latest design, combining the charging and signal jack into one, the headphone and USB jack into one, and the jack adopts the popular Type-C jack. The number of jacks is reduced from 4 to 2, and the dust cover in the jack area is configured, effectively reducing the risk of water and dust entering the instrument and prolonging the instrument's service life.

● LVR9 recording and data saving function: it can save the on-site audio and image information, and people who are not on the scene can also assist in detecting the pipeline through the saved on-site audio and image information.

● One-click switching between Chinese and English.

● The receiver probe adopts high-sensitivity piezoelectric sensing technology, which has high sensitivity and can monitor feeble sound signals.

● The sound quality is soft and clear, and it has a 5-level hearing protection function to prevent loud sounds from entering the headphones and protect the user's hearing well.

● The detection mode shows the size of the signal measured at each point through a square bar diagram, which is convenient for comparison and makes it easier to locate the position of the pipe.

● The multi-functional, high-brightness color bright touch screen allows the user to see the content displayed on the screen under the scorching sun.

● With wireless Bluetooth function, wired and Bluetooth wireless headphones can be used simultaneously or separately. One receiver can listen to two people at the same time, which improves the detection accuracy and efficiency. Bluetooth pairing is simple and fast, and the instrument automatically matches the Bluetooth headset after it is turned on.

● The listening bandwidth can be adjusted freely, and the minimum bandwidth can reach 20Hz.

● The receiver displays the size and characteristics of the collected vibration signal in real-time, and when accurately positioning the underground pipeline, when listening to the sound and judging the tube position by the sound characteristics and size, it can also be comprehensively judged by the value of the target frequency of the current band on the screen, the signal size and the spectrogram.

● The receiver can be used with other similar gas PE pipeline locator transmitters on the market. The receiver has the function of accurate frequency measurement, which can measure the transmission frequency of other brands of pipeline acoustic wave locator transmitters and can be matched.

● The receiver probe and box are small and easy to carry. The triangular jaw can quickly install the probe without disassembly, and the hard ground mode and soft soil mode can be quickly switched.

● By manipulating the knob rotation and pressing on the receiver, the gain and volume adjustment, mute, and measurement functions that are commonly used in ordinary detection can be realized.
