Oil tanks shall be equipped with which type of device?

• A. Gauging
• B. Float Switch
• C. Pressure Relief Valve
• D. Thermostat

Answer: (A)

Knowing the oil level in a storage tank is essential for safe operation and inventory control. A gauging device provides a direct indication of how much oil remains, allowing you to schedule deliveries, prevent overfill, and track usage accurately. The other options serve different roles: a float switch is typically used to control pumps or trigger alarms based on level, but it isn’t the standard device required to indicate the tank’s contents; a pressure relief valve protects against overpressure in pressurized systems, not for basic storage tanks; a thermostat controls temperature, which isn’t the issue here. So gauging is the device used to determine and monitor the oil level in tanks.
