🔍 Key Concepts

• Behavior of a tubular sight glass connected at the top and bottom of a tank • Effect of air pressure in a hydro pneumatic (air-over-water) tank on the indicated level • When and why you would blow down or drain a sight glass

💭 Think About

• Picture how the sight glass is piped: where does the top connection go, and where does the bottom connection go on the tank? What happens to the water level in the glass if both are open and under the same pressure? • Think about whether extra air pressure inside the tank makes the water in the glass stand higher, lower, or the same compared to the water in the tank. • Ask yourself in what type of system (e.g., boilers vs. potable water tanks) you routinely blow down the gauge glass before each reading, and why.

✅ Before You Answer

• Verify that in a properly installed sight glass, both top and bottom cocks are open and the glass is at the same pressure as the tank. • Confirm whether static liquid levels in communicating vessels (tank and glass) under the same pressure are equal or different. • Consider whether routine blowdown of a potable water sight glass is standard practice or mainly associated with steam boilers.
