A remote monitoring system for a mobile storage tank having a product container
in which a remote telemetry unit gathers liquid level and head space pressure data
and global position data. The remote telemetry unit effects a wireless transmission
of a standard message structure containing the pressure and level data and the
global position data. In addition, in case of a storage tank having a thermal shield
fluid, pressure and level data for the shield fluid itself may also be in the standard
data record as well as acceleration data from an accelerometer to indicate tank
damage. If upset conditions of pressure and liquid level are reached in the thermal
shield and/or product container, vapor may be vented in accordance with preset
programming in order to attempt to reestablish liquid level and vapor pressure
above set points.
