Level gauge zero point
Thread Content
Is the zero point of the level gauges in towers and storage tanks based on the bottom of the equipment or the level gauge port below it?
Generally, the bottom of the tower or tank serves as the zero point for the level gauge. For differential pressure level gauges, the user needs to set the initial liquid level height in the DCS system ； For magnetic flap and glass plate level gauges, when installing the indicator panel, the user adjusts the zero point to the bottom level or sets a non-zero point as the starting level for measurement.
With the bottom of the level gauge as point 0, the level gauge cannot measure the liquid level below the bottom of the tank
Agree with what was said on floors 3 and 4.
It doesn’t matter which one is used as the zero point; it depends on the requirements of the operation
Take the lower part of the level gauge. Assuming that the bottom of the tank is set as the zero point, then how does the level gauge display values when the liquid level changes between the bottom of the tank and the lower part of the level gauge?
What type of level gauge? One sampling port or two?
Idiot, the liquid level is originally a relative value anyway

When setting the initial liquid level height for a differential pressure level gauge in a DCS, what is used as the reference point? “What is used as the “starting point” to indicate the “liquid level at zero”?
