Remote Seal Transmitters Temperature Error
Calculation of temperature error for remote seals The following equation is used to calculate the temperature error for remote seals: dp = (tRS - tCal) . fRS + (tCap -…
Capillary Tubing Pressure Sensor Temperature & Elevation Problems
Capillary tubing provides a convenient method to separate a pressure instrument such as a gauge or transmitter from the actual process connection, allowing the instrument to be installed in a…
Effects of Symmetric and Asymmetric Capillary Tube Pressure Measurement
Symmetric capillary 1. Seal Effect: If the ambient temperature increases the capillary volume V will tend to exert forces on the DP seal (both sides). If both capillary have the…

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…
