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.
The most accurate and fast acting constants loss monitoring system of its kind. Capable of detecting a loss of agent mass to within 1% in Inert gas, CO2 and Clean Agent systems, and in addition to weigh loss, will provide accurate percentage pressure loss of Inert gas systems associated with agent contents leakage.
Acoustic pressure monitoring is exactly what it sounds like. The use of acoustic pressure monitoring enables quick and easy detection of even small changes in pressure, which can indicate a potential leak or other issue. It is an effective tool for ensuring the safety and stability of container contents without the need for invasive pressure testing or other time-consuming procedures. Whether you are dealing with sensitive materials or simply require precise pressure monitoring for industrial applications, acoustic pressure monitoring can provide a reliable and efficient solution.
Acoustic pressure monitoring is a non-invasive technique that monitors the internal pressure of a sealed container by detecting changes in resonant frequency. Every object has an intrinsic resonant frequency, which is the frequency at which it “vibrates” or “rings” when excited.
The intrinsic properties of an object, such as its shape, size, thickness, and material, can affect its resonant frequency. In the case of a sealed and pressurised container, such as those used for industrial compressed gases, the tension in the material is also a significant factor. The physical principles that explain how tension affects resonance in a string or wire can also be applied to more complex systems, including those used for gas pressure monitoring and pressure testing.
In the case of a pressurised container, such as a fire cylinder, the tension within the walls plays a vital role in determining the resonant frequency. The tension is generated primarily by the internal pressure of the cylinder, resulting in a quantifiable relationship between pressure and resonant frequency. By accurately adjusting for changes in temperature, the pressure can be used to predict the exact amount of gas present within the cylinder. This highlights the significance of pressure monitoring and testing, particularly for industrial compressed gases, to ensure safe operation and efficient management of contents.
Therefore, Acoustic pressure monitoring detects even minor changes in the internal pressure of a cylinder by safely exciting resonant vibrations, analysing them, and carefully calibrating the system. Temperature measurements can be combined with pressure testing, to utilise the most accurate mathematical models available, to distinguish changes in contents (i.e., a leak) from fluctuations in pressure caused by temperature.
Contents monitoring of fire cylinders, pressure testing and monitoring can be an effective solution. However, an alternative option is to monitor the mass of the contents. This method is particularly useful for industrial compressed gases, as it provides a simple and effective way to detect any leaks or changes in the quantity of gas, and eliminates factors such as temperature.
For instance, the mass monitoring method can be used to monitor liquefied gaseous systems, which contain both a propellant gas and a liquefied extinguishing agent. While this method cannot differentiate between a loss of agent or a loss of propellant gas, any type of leak can still be rapidly detected and addressed.
For non-gaseous systems, pressure loss is often used as a reference point, but it is equally important to report mass loss as an equivalent loss in temperature-adjusted pressure. To address this, a digital fixed weight monitoring system such as PermaMass® FEATHERWEIGHT can be used. This system utilises the intrinsic link between mass and pressure in pressurised gases. When connected to inert gas cylinders, PermaMass® FEATHERWEIGHT can automatically convert any measured mass loss into an equivalent loss of pressure, which is adjusted to the original fill temperature and compared to the fill pressure. This helps to ensure compliance with regulations and provides a comprehensive understanding of how systems are performing.
Inert gas fire suppression systems, like Inergen™, are commonly used to protect high-value assets and critical infrastructure in occupied spaces, where CO2 systems are not appropriate due to the risk to human life. In the event of a fire, if this concentration is not met, or is met for an insufficient length of time, there is no guarantee that the fire will be successfully extinguished, potentially leading to catastrophic damage. It is vital, therefore, to accurately monitor the contents of fire extinguishing cylinders, to ensure that there is no leakage of agent that could lead to an area being unsafe without you even knowing about it.
Therefore, proper contents monitoring of fire extinguishing cylinders, therefore, becomes essential to avoid any leakage of agent that could potentially lead to a hazardous situation. Pressure monitoring is vital for inert gas fire systems, as per the standards such as ISO 14520 and NFPA 2001, where temperature-adjusted pressure is a direct indication of cylinder contents. If the true loss of pressure is more than 5%, the cylinder needs to be refilled or replaced.
For this reason, accurate pressure monitoring, coupled with precise temperature adjustments, is critical for effective and reliable monitoring of an inert gas fire system. Regular and reliable gas pressure monitoring can detect any leaks long before the 5% threshold, ensuring a higher level of safety and security for the assets that the fire system is designed to protect. Trusting in our gas pressure monitoring solutions will give you peace of mind that your industrial compressed gasesare being monitored accurately and reliably.
Noninvasive monitoring encompasses various techniques that allow for the assessment of physiological parameters without the need for invasive procedures. Some common types of noninvasive monitoring include:
Vital signs monitoring: This includes measuring parameters such as heart rate, blood pressure, respiratory rate, and body temperature using external devices or sensors.
Imaging techniques: Noninvasive imaging techniques like ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), and X-rays provide detailed internal images of the body without invasive procedures.
Wearable devices: Technological advancements have led to the development of wearable devices that can monitor vital signs, activity levels, sleep patterns, and other health-related parameters.
Point-of-care diagnostics: Noninvasive tests such as blood glucose monitoring, pulse oximetry, and urine analysis can provide valuable diagnostic information without the need for invasive sampling.
Non-invasive measurement refers to the process of obtaining data or measurements from the human body without the need for invasive procedures that penetrate the skin, body cavities, or other internal structures. Instead, non-invasive measurements are performed externally or with minimal intrusion, utilizing external sensors, imaging techniques, or wearable devices. This approach reduces patient discomfort, eliminates the risk of infection or complications associated with invasive procedures, and allows for continuous monitoring or assessment of physiological parameters in a safe and convenient manner.
