Steam boiler drum level measurement technology comparison

Sep 22, 2020 · The sensor electronics uses the change in speed and applies the slower speed to the entire measurement span, compensates for the change, and outputs an accurate level measurement. This adjustment happens in real time with each signal transmission, ensuring an accurate continuous level measurement, even during startup and shutdown.

Level sensor - Wikipedia

Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface.Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a peak. The substance to be measured can be inside a

Effective Boiler-Level Control | HPAC Engineering

Jan 01, 2008 · Multiple conductivity probes (Figure 5) are used to give point measurements of water level. When water touches the probe tip, current flows through the sensor's circuit, triggering an action through an associated controller. Two probes are necessary to switch a pump on and off at predetermined levels.
