Portagas®

Acoustic, non-invasive pressure monitoring system, in an intuitive Android platform.

Portagas® is a world’s first technology for non-invasive, non-destructive monitoring of pressurised, inert gas systems.

It is a unique and innovative solution designed to monitor the pressure of pressurized, non-liquefied inert gases and compressed gas cylinders, including Inergen®, Nitrogen, Oxygen, Propane, Methane, Chlorine, Ammonia, Hydrogen, and CO2.

Utilizing sophisticated signal processing and acoustic technology to detect even minor fluctuations in internal cylinder pressure, with precision below the 5% required by regulations and by detecting marginal changes in the internal cylinder pressure with precision well below 5% demanded by the regulations, making it a valuable tool for ensuring safety and compliance.

Overview

Non-invasive pressure monitoring system

 

Portagas® is a unique and innovative contents monitoring solution for pressurised, non-liquified inert gas cylinders. Through a combination of sophisticated signal processing and data-driven, empirically verified algorithms, Portagas® utilises acoustic technology.

Pressure alone is not sufficient to fully understand the status of a cylinders’ contents; the pressure of a sealed container is directly related to its temperature. This means that, unless properly adjusted for changing temperatures, a change in pressure does not necessarily mean that the cylinder is leaking. Conventional pressure gauges typically address this by indicating a range of acceptable pressures based on different temperatures. This is a useful indication; however, these ranges are typically quite broad and relies on the personnel conducting the checks to properly account for the temperature.

The Portagas® tackles this issue head on, with an infra-red thermometer built into the sensor that will take a current temperature measurement at the point of testing. This temperature is then used, along with fill pressure and fill temperature, to determine precisely what the pressure should be at the current temperature. We use the most accurate models available for pressurised gases in making these adjustments, accounting for the intrinsic forces and characteristics of the contained gas.

This temperature-adjusted pressure is then compared with the pressure determined acoustically by the Portagas®, allowing it to intelligently and automatically determine whether an observed change in pressure is due to changing temperatures or a loss of contents, all with the tap of a finger.

Portagas® also allows you to effortlessly keep track of your maintenance. Each test you conduct can be saved to the device along with a date and time. The full record of all the tests conducted can then be viewed and filtered by date and site on the device, or you may choose to export the data via email or USB. This data can be exported as either a simple CSV file, for integration into existing records, or in an automatically generated PDF report.

Applications

Types of gases: Inergen®, Nitrogen, Oxygen, Propane, Methane, Chlorine, Ammonia, Hydrogen, CO2.

List of applications:

  • Healthcare – Respiratory therapy, anesthesia, and other medical applications.
  • Pharmaceutical – Production of medicine.
  • Food and Beverage – Carbonation and preservation of food and beverages.
  • Power Generation – Fuel sources for power generation and heating.
  • Oil and Gas – Maintain pressure and prevent corrosion in oil and gas pipelines.
  • Manufacturing – Used in welding, cutting, and other industrial processes.
  • Environmental – Monitor and reduce greenhouse gas emissions.
  • Mining – Mine ventilation and safety.
  • Chemicals – Production of chemicals and fertilizers.
  • Transportation – Alternative fuels for vehicles.
  • Agriculture – Enrich the air in greenhouses to enhance plant growth.
  • Construction / Metal – For welding, cutting and heating.
  • Textile – Spinning and weaving of textile fibers.
  • Aerospace – Pressurization and propulsion.
  • Refrigeration – Refrigerants in commercial and industrial refrigeration systems.

Inergen™ is typically stored in seamless cylinders at pressures between 100-200 Bar. At such pressures they are subject to slow seepage of contents or occasionally accidental discharge. If the gas is insufficient to develop the design concentration required the fire event will not be extinguished. This is used to detect even minor changes in the internal pressure, with precision comfortably exceeding the 5-10% agent and pressure loss thresholds cited in regulations such as NFPA 2001 and ISO 14520.

Frequently asked questions

Gases stored in a sealed container exert pressure on the internal walls, which is dependent on both the temperature of the gas and the amount of gas present. Thus, pressure, when corrected for temperature variations, can be used as a direct indicator of the quantity of gas stored in a cylinder. Fire industry regulations, such as ISO 14520 and NFPA 2001, require regular monitoring of pressure in inert gas systems.
Portagas® detecting changes in pressure from an initial known value. These changes in pressure are adjusted for changes in temperature and used to determine precisely whether an observed change is due to temperature or a leak.
Portagas® keeps records of all tests, organised by date, time, site and cylinder. These records can easily be filtered and exported via email or USB as either a simple CSV file, or as an automatically generated PDF report.
The Portagas® works on pressurised, seamed and seamless non-liquified inert gas and compressed gases cylinders.
