Hydrostatic Level Measurement Explained | Head Pressure, Load Cells and DP Transmitters
This lesson explains how liquid level is measured in a vessel using hydrostatic pressure, load cells, and differential-pressure transmitters. It shows how fluid height and density determine head pressure, how vessel weight can be converted into level using load-cell measurements, and why closed or pressurized vessels need vapor-space compensation with a DP transmitter. Ideal for process control, instrumentation, and industrial measurement students.
