Interface Level Measurement Selection Guide
The table gives some guidance related to the oil-water interface level measurement for a single technology. However, it is important to understand the need for measurement. For some application, several…
Guided Wave Radar Level Sensor Pressure and Temperature Effects
High pressures/temperatures reduce the propagation velocity of the measuring signals in the gas/vapour above the liquid interface to be measured. The result of the high pressure/temperature is a systematic measuring…
Manual Level Measurement
Although the scope of the document is about fixed installed measuring instruments, manual measurements should be at least discussed briefly. Manual measurements are still quite often used as they are…
How can we use a DP Flow Transmitter for Level Measurement
Firstly, I need to clarify, that a DP transmitter is not only used for measuring flow, as the user referred to in his question, to a DP flow transmitter. A differential pressure…
Magnetic Level Indicator Principle, Limitations, Installation and Calibration
Measurement principle The Magnetic Level Indicator (MLI) is a simple, rugged instrument designed to indicate level or interface. It indicates level using a float magnetically coupled to an index or…
Nuclear Interface Level Measurement Principle, Limitations, Installation and Calibration
Measurement principle The nucleonic measuring principle is based on the attenuation of gamma radiation as it penetrates materials. The radioactive isotope (gamma source) is installed in a container, also referred…
Electro Pneumatic Valve Positioner Schematic & Principle
Electro Pneumatic valve Positioner is used to control the valve stem position from open to close position or vice versa. A simple design and concept equals a simple operation of…
Hybrid Level Measurement Principle, Selection, Installation, Limitations and Calibration
The level measurement is based on a hybrid technology: which consists of capacitance and GWR. The system is based on the GWR technology, whereas for interface applications this method is…
