Atmos Tightness Monitor is a statistical tightness monitoring system used to test for leaks in airport hydrants. It uses sequential probability ratio test (SPRT) to detect changes in the overall pressure. SPRT analyzes the pressure variation over a high pressure and then a lower pressure to confirm the tightness of a test section. The system does not require temperature sensors for leak confirmation. Atmos Tightness Monitor leak detection technology is widely used in liquid pipelines, monitoring approximately 200 pipelines many of which transport jet fuel over distances from as small as 100 meters to a few kilometres. Atmos successfully adapted and tested Atmos Tightness Monitor for airport aviation fuel hydrant systems, initially for military airports and naval bases where it has been in use since 2004. Atmos Portable Tightness Monitor was developed  based on many years of experience working with leak detection systems on airport hydrants. Testing takes no more than 45 minutes with on-screen prompts notifying the stages of the test to the operator.

Atmos Wave Leak Detectors


Approx. Rs 8 Lakh / UnitGet Latest Price

Atmos Wave detects the rarefaction wave caused by a leak in a pipeline. When a leak occurs, a rarefaction wave travels in both directions along a pipeline. Using fast response pressure meters Atmos Wave filters the pressure signals to find those with the frequency and magnitude of a leak. The time at which the pressure signal reaches each pressure meter is used to determine the location of the leak extremely accurately. Atmos Wave is the result of several years of research and development directed at producing a pressure-based leak detection system that is capable of differentiating between pressure waves that originate from pinhole leaks and the background noise and other pressure signals caused by normal pipeline operations. Extensive performance evaluation and field trials have proven that Atmos Wave can detect small leaks without generating false alarms due to pipeline transients or process noise.

Features include

· Very low false alarm rate

· Based on high performance, off the shelf pressure meters from reputable manufacturers

· Detection of leaks less than 1% of nominal flow-rate within 4 minutes, resulting in a very small product release before a confirmed leak alarm

· Detection of existing pinhole leaks, under running or shut-in conditions

· Location of leaks within ± 100 to ± 400 metres depending on operational conditions during the leak

· Dedicated data acquisition unit (AWAS) certified to the European Union's ATEX Zone 1 standard, with local data storage to mitigate the effect of communication failures

· Detection of pipeline thefts effectively including the closure of a theft valve, which is very useful for identifying theft locations

Atmos Pipe


Product Price :Get Latest Price

Atmos Pipe has detected and located more than 500 leaks in gas and liquid pipelines and is the most tested leak detection system in the world. It employs Atmos’ unique statistical volume balance method to provide an extremely reliable leak detection system that can detect both onset and existing leaks. Typically the system gets flow and pressure data from a SCADA system and calculates the probability of a leak at regular intervals e.g. every 5 seconds. To minimize false alarms, pattern recognition techniques are used to identify changes in the relationship between the pressure and flow when a leak occurs.

Atmos Pipe has the ability to identify operational changes in the pipeline and can detect leaks during transient operations. Data validation algorithms and filtering techniques are employed to improve data quality. Flow measurement errors are also learned to assist in the provision of reliable and sensitive leak detection. Atmos Pipe has been successfully applied to the following pipelines ranging from 2 km to 1740 km, 0.5” to 80” in diameter. The system is best suited for pipelines carrying gas, liquid and multi-phase pipeline leak detection.

Atmos SIM


Approx. Rs 8 Lakh / Unit(s)Get Latest Price

Atmos SIM is a pipeline transient simulator developed from the ground up by Atmos International ("Atmos") for both online and offline applications. Additionally Atmos SIM can be used for Gas and liquid pipelines as well as transmission and grid network systems. Whether you are a pipeline modeller or a pipeline control room engineer, Atmos SIM has the features to address your requirements. ATMOS SIM models the hydraulic behaviour of both gas and liquid pipelines accurately. SIM Offline supports the planning and design analysis of pipeline networks, SIM Online gives the pipeline operators a view into the un-instrumented areas of the pipeline to assist them in running their pipelines. The same configuration applies to ATMOS SIM Offline and Online. Online saved states can be imported to SIM offline for realistic scenario analysis and emergency studies. Atmos SIM on-line uses a unique state estimator to provide the most robust and accurate on-line simulation results in the market. It minimizes the effect of measurement errors by the use of confidence levels in individual meters. This is especially useful for large pipeline networks. Atmos SIM is a powerful and user-friendly tool for the following applications on any gas pipelines:

·         Design and sizing of new pipelines and associated equipment such as compressor, heater and cooler

·         Operational scenario analysis for planning, emergency or upset analysis

·         Calculation of flow, pressure, temperature, gas properties along a pipeline

·         Look-ahead modelling

·         Line pack (inventory) calculation and survival time analysis

·         Composition tracking

·         Pig tracking

·         Leak simulation

·         Simulation of natural gas, low pressure ethylene and chemical pipelines

·         Model-based leak detection.
