Pressure level probes are submerged directly into the liquid and remain permanently floating above the tank bottom. The measurement is carried out according to the hydrostatic principle. The gravity pressure of the liquid column causes an expansion of the pressure-sensitive sensor element, which converts the measured pressure into an electrical ...
Tank level information is often sent to computers that calculate hull stresses such as shear forces and bending moments. [4] Various other functions are available in some cargo control rooms. [4] Many offer the person in charge additional monitoring and control systems, [4] the ability to monitor inert gas systems, [4] and tank pressures. [4]
The other method is vacuum monitoring where vapour sensor monitors interstitial spaces of the tank. In case of the leakage the vacuum of the space begins to change. It is also possible to partially fill the interstitial space of the tank with a monitoring fluid (brine or glycol solutions ). Once the level of the fluid changes, a leak may be ...
The operator interfaces which enable monitoring and the issuing of process commands, such as controller setpoint changes, are handled through the SCADA computer system. The subordinated operations, e.g. the real-time control logic or controller calculations, are performed by networked modules connected to the field sensors and actuators .
The countrate of the monitor varies dynamically, so that a measurement time interval must be specified. Also, these are integrating devices, meaning that some finite time is required to accumulate radioactivity onto the filter medium. The input to the monitor is, in general, a time-dependent concentration in air of the specified nuclide.
In the United Kingdom the professional body is the Chartered Institute of Plumbing and Heating Engineering (educational charity status) and it is true that the trade still remains virtually ungoverned; [49] there are no systems in place to monitor or control the activities of unqualified plumbers or those home owners who choose to undertake ...
Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood ().Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
The video was originally uploaded on Facebook. Later, a YouTube user reposted the video onto YouTube on the day after; June 19, 2012, with the title "Making The Bus Monitor Cry", alongside two other videos with the titles "Bus Monitor Harassment", and "Bus Monitor Harassment 2". Within a few days, it had been watched by millions of viewers.
