Where should pressure gauges be installed in an LP Gas System at a bulk plant?

Pressure gauges are critical components of an LP Gas system, especially in a bulk plant setting, because they help monitor pressure levels to ensure safety and system integrity. Installing pressure gauges at the container opening or directly attached to the container allows for immediate access to the pressure readings of the gas in the container.

This location provides a direct and accurate measurement of the pressure within the container, which is essential for operational safety and efficiency. Monitoring the pressure at this point is vital for preventing overpressure situations and ensuring that the gas delivery system operates within safe parameters.

Other options, while they may involve monitoring or controlling gas flow, do not provide the same level of direct pressure measurement related to the container itself. For instance, placing a gauge above the storage tank or on the discharge line may measure system pressure but does not reflect the exact pressure of the gas stored in the container, which is critical for safe handling and operational protocols.
