What is Displacer Level Sensor ?

S Bharadwaj Reddy
Displacer level sensor use Archimedes’ Principle to detect liquid level by continuously measuring the weight of a displacer rod immersed in the process liquid. The displacer is cylindrical in shape

Magnetostrictive Level Transmitter Calibration Procedure

S Bharadwaj Reddy
Before we calibrate the magnetostrictive level transmitter, we must aware that the float has been produced at factory as per process fluid Specific Gravity (SG), while we will use water

Boiler Three Element Controller Philosophy

S Bharadwaj Reddy
A single element control system is one with just one control input, a two element control system is one with two control inputs, etc. A three-element boiler water level control

Effects of Symmetric and Asymmetric Capillary Tube Pressure Measurement

S Bharadwaj Reddy
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

S Bharadwaj Reddy
Interface Level Measurement Table gives some guidance related to the oil–water interface level measurement for a single technology. However, it is important to understand the need of the measurement. For

Guided Wave Radar Level Sensor Pressure and Temperature Effects

S Bharadwaj Reddy
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
