Level gauge

What are the submersible hydrostatic level gauges? Can it only be used at atmospheric pressure?
Both pressurized and non-pressurized containers are supported, as well as submersible level gauges; when the container is pressurized, two probes are required to determine the liquid level by taking a difference
After looking at the selection materials posted by my brother, I’ve basically understood the various types of submersible level gauges available today.
For normal pressure, an immersion type works fine; it’s not necessary for non-normal pressure
Submersible level gauges are widely used, and they come with diaphragm-type probes
It’s used at atmospheric pressure; it’s determined by the pressure at the bottom of the tank. Once it’s sealed, there’s a differential pressure
