🔍 Key Concepts

• Relationship between liquid level and hydrostatic pressure at the bottom of a tank • How a bubbler / pneumatic level gauge works to show level from a remote location • Difference between controlling flow or pressure and simply measuring level

💭 Think About

• Look at the lines going into and out of the tank: does any pipe actually carry cargo out of or into the tank, or is it only air being forced down and bubbles released? • If you squeeze the bulb at point A, what happens at the submerged outlet at E, and what will change at the indicator marked C? • Ask yourself: is anything here throttling a liquid line, or is it using air pressure to sense how deep the end of the pipe is below the surface?

✅ Before You Answer

• Verify whether the pipe inside the tank is open to the tank liquid only at the very bottom (E) and otherwise contains air, not cargo • Check if component C looks like a gage/tube for indication, not a valve or pump for controlling flow • Confirm that no symbol in the drawing represents a control valve in a liquid line; instead, the only valve is in the air line at A/B
