SUBCHAPTER FINSTRUMENTATION AND ELECTRICAL SERVICES
RULE §14.2501Liquid Level Gauging

(a) LNG containers shall be equipped with liquid level gauging devices. Density variations shall be considered in the selection of the gauging device. Consideration shall be given to a secondary or backup gauge. At least one of these gauges shall be replaceable without taking the container out of operations.

(b) When the container filling rate is greater than 1.0% per day, the container shall be provided with a high-liquid-level alarm which shall be separate from the liquid level gauging device. The alarm shall be set so that the operator will have sufficient time to stop the flow without exceeding the maximum permissible filling height, and shall be located so that it is visible and audible to personnel controlling the filling. A high-liquid-level flow cutoff device, if used, shall not substitute for the alarm.

(c) Containers with a capacity of 93,240 gallons or less which are continuously attended during the filling operation may be equipped with trycocks in lieu of the high-liquid-level alarm.
