Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
The basic principle is that the magnetic field "leaks" from the steel at areas where there is corrosion or missing metal. To magnetize the steel, a powerful magnet is used. In an MFL (or Magnetic Flux Leakage) tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field. Analysts interpret the chart recording ...
Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the release is stopped in time.
As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [3] as well as to check oxygen distribution devices and cabin pressurization systems.
There exists a few papers that systematically compare various model checkers on a common case study. The comparison usually discusses the modelling tradeoffs faced when using the input languages of each model checker, as well as the comparison of performances of the tools when verifying correctness properties. One can mention:
VisualVM is a visual tool integrating several commandline JDK tools and lightweight profiling capabilities. It is bundled with the Java Development Kit since version 6, update 7. FusionReactor , Java application performance monitoring - low overhead, production grade tools for production debugging, code profiling, memory and thread analysis
A residual gas analyzer (RGA) is a small and usually rugged mass spectrometer, typically designed for process control and contamination monitoring in vacuum systems.When constructed as a quadrupole mass analyzer, there exist two implementations, utilizing either an open ion source (OIS) or a closed ion source (CIS).
