Hybrid level systems are also known as Hybrid Inventory Measurement Systems (HIMS). This can be viewed as the ‘emerging technology’ of the tank gauging world.
It stands out from conventional methods because it is able to measure level by means of any conventional automatic tank gauging (ATG), volume by pressure sensor and density, just like current HTG.
Hybrids, however, utilise level measurement equipment, a ‘smart’ pressure transmitter and a temperature measurement device, which allows the volume to be calculated more accurately than can be achieved using HTG
This is the most recent evolution of tank measurement methods and is suggested to achieve greatest accuracy of all present methods because it presents a synergy of existing, diverse, level measurement technology.
