GAS & FLAME DETECTION, ENVIRONMENT MONITORING

Gas Leak Detection System is based on the determination of static, dynamic pressure, flow in the pipeline using primary converters and further processing of data using the following methods: a balanced method; pressure profile; pressure wave; acoustic algorithm. The main function of the system is to determine the occurrence of a leak from a main (pressure) oil pipeline or oil product pipeline and a leakage coordinate.

Infrared gas leakage detectors

Technologies traditionally used in fixed installations for the detection of hydrocarbon gas leaks, such as catalytic / infrared sensors and trace IR sensors, have one limitation: to detect leaks, the sensor should be located in close proximity to a source of gas leakage or within a certain area. Unfortunately, environmental conditions, such as changing the wind direction and rapidly dispersing the gas cloud emerging from the external installation where the leak has occurred, often lead to malfunctions of traditional gas detection systems due to the fact that the gas simply does not reach the gas analyzer.

Ultrasonic gas leak detection system

Ultrasonic gas leak detectors are based on reliable microphones and provide detection of leaks in outdoor installations by detecting high-frequency ultrasound emitted in all high-pressure gas leaks. Due to the unique sensitivity to ultrasound, the gas delivery of the gas analyzer is not a prerequisite for operation – only an acoustic signal emitted at the leakage point is sufficient. Unlike other technologies, ultrasonic gas leak detectors do not provide for fine optical tuning, which may be disturbed by vibration, rain and fog, or solar radiation. Also, they are not sensitive to saturation with poisonous or highly concentrated gases. At the same time, the microphones of the stainless-steel detectors do not require maintenance.

Gas Leak Detector units

For ultrasonic detection of gas leaks, acoustic sensors are used to monitor the presence of noise fluctuations that are not detected by human hearing in the working environment. The sensor and electronics are able to detect these ultrasonic vibrations (from 25 to 100 kHz), excluding audible frequencies (from 0 to 25 kHz). Unlike traditional gas detectors that measure accumulated gas, ultrasonic gas detectors “hear” the leak, activating an early warning system.

Detectors react to sound from gas leaks at ultrasonic frequencies. The sound of the leakage mainly depends on the amount of leakage and gas pressure. In most rooms, most of the process noise is in the audible range, while in normal operation, limited ultrasonic noise is generated. Gas under high pressure generates ultrasound (25-100 kHz), which detects the detectors, despite the presence of audible noises.
