GL18-LVR8 is an advanced technology, powerful, lightweight, durable, fashionable and exquisite, highly integrated acoustic locator for gas PE pipeline. The design of this product adheres to good product performance, high-quality manufacturing technology and high-level user experience, focusing on improving work efficiency, enhancing practicality and durability while taking into account small, light and portable. GL18-LVR8 is a heavy milestone product developed by Jietong Zhichuang Company on the basis of years of research, development and manufacturing of acoustic pipeline detection instruments. GL18-LVR8 promotes the development of acoustic locator for gas PE pipeline again with its various characteristics.

Characteristics of transmitter GL18:

● The transmitter can be equipped with wireless remote control function: the transmitter can be equipped with wireless remote control function, which can remotely control the start, stop and FM power of the transmitter within 3 kilometers, and the remote controller can also remotely monitor the status of the transmitter;

● Fully consider the requirements of practicality and portability when designing. The transmitter is smaller, lighter and more durable;

● The transmitter is equipped with LORA module, which is more beneficial for the staff to remotely control the transmitter. The remote control function greatly improves the working efficiency, and reduces the need for commuting cost transmitter to have a remote controller with matching remote control function and a built-in LORA communication module, so as to ensure that the switch and frequency conversion power of the transmitter can be stably controlled remotely within a kilometer range, and the running state of the transmitter can also be monitored remotely;

● The transmitter can be remotely controlled for on-off and frequency and power adjustment (optional) through the matched receiver;

● Everything is based on the design principle of simplicity and practicality. The transmitter uses four constant frequencies and two variable frequencies with the best positioning effect. The six transmission frequencies ensure that all kinds of environments can be easily dealt with and can be applied to all kinds of complex and harsh detection environments. The transmitter power can be adjusted in 8 steps, according to the detection distance and output power. There is no blind spot detection in short distance, medium distance and long distance. The cooperation of multi-frequency and multi-power can not only ensure the accuracy but also ensure the detection distance, and also achieve better detection effect;

● The transmitter has a built-in ultra-large capacity battery, which has a long standby function for 12 hours continuously;

● The transmitter has higher output power, which can transmit stronger signals and realize deeper and farther detection;

● Emit a specially modulated frequency, which greatly improves the signal recognition of the instrument in noisy environment.

Features of receiver LVR8:

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

● The listening quality is soft and clear, and it has five-level hearing protection function, which can prevent loud sound from entering the earphone and protect the user's hearing;

● Recording and data saving function: the live audio and image information can be saved, and people who are not at the scene can also assist in detecting the pipeline through the saved live audio and image information;

● In the detection mode, the size of the signal measured at each point is represented by a square column diagram, which is convenient for comparison and easier to locate the pipeline position;

● With sounding function, sounding and detection can be completed at one time, and the operation is simple and efficient. Adjustable according to environmental signals;

● Multifunctional color smart touch screen, without any buttons, with clear and intuitive graphic display;

● With wireless Bluetooth function, wired headphones and Bluetooth wireless headphones can be used at the same time or separately. One receiver can listen to two people at the same time, which improves the detection accuracy and efficiency;

● The audio width can be adjusted freely, and the minimum bandwidth can reach 20Hz;

● The receiver displays the frequency of the collected vibration signal in real time, and can also watch the numerical value to assist positioning when listening;

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

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

● The strap design with adjustable length of the receiver is more convenient for on-site operation;

● By operating the knob on the receiver to rotate and press, the functions such as gain and volume adjustment, mute and measurement that are often used in detection at ordinary times can be realized.
