Overview

This leakage monitoring technology has been maturely applied in nearly 10000 kilometers of crude oil and refined oil pipelines at home and abroad. Timely detection of over a hundred incidents of drilling and oil theft has reduced the losses and hazards caused by pipeline leaks. Easy installation, real-time online warning. Timely reporting of leaks can reach within 50 meters.

System Advantages

Easy installation;

Relying on sound wave transmission for leak detection, accurate and fast, not affected by multiphase flow;

Fast, coherent, and does not require complex static data statistical analysis to define the entire system, or qualitative (or pre-defined) system behavior, unaffected by operating conditions;

Using a more advanced multi-layer iterative data processing method, with SMARTDRIVE (signature signal matching filter) technology, combined with differential filtering, moving average filtering, adaptive dynamic threshold adjustment, data modeling software, etc., greatly reduces false alarm rates;

Each data processor has GPS tags for accurate data synchronization;

No need for repeated measurements, minimal maintenance workload.

System Advantages

Automatic control valve - connected to the automatic control valve, automatically shuts off when an alarm is triggered.

Positioning speed - can detect and accurately locate leakage points, regardless of the size of the leakage hole, with a positioning speed of less than 100 seconds in liquid.

Multiphase flow - not only can it monitor gas and liquid single-phase flow leaks, but it can also monitor multiphase flow accurately in non full flow, condensation, and even high vibration environments caused by multiphase flow segments and flow environments.

Main technical indicators

rapid detection	Regardless of the size of the leakage hole, detect and locate the leakage point within 100 seconds
precise positioning	Less than 50m
reliability	*A system that can be connected to an automatic control valve for shut-off operation
sensitivity	Liquid pipeline detection is less than 0.1% of the flow rate, approximately less than 0.1 inches
	Gas pipeline detection less than 0.001% flow rate
	Background noise and sensor bandwidth, as well as sensor layout, need to be considered
working conditions	Normal operation in the following situations: pump start-up and shutdown, valve opening and closing, static and non static flow, non full flow, no flow, etc
