Liquid gas flow can now be calculated with precision using Sierra Instrument’s new cryogenic version of its InnovaMass 240 multivariable mass vortex flow meter.

Sierra introduced the new cryogenic version for the advanced, more reliable measurement of liquefied gases down to -330°F (-200°C), including liquid nitrogen, liquid oxygen, liquefied natural gas (LNG), liquefied petroleum gas (LPG).

While liquid gas flow may have traditionally been gauged by inexact turbine flow meters in the past, with the new cryogenic InnovaMass containing no moving parts that will either wear out or require service, liquid gas flow can now be calculated with precision and increased service life.

Using a special cryogenic temperature RTD, mass calculations are achieved with the latest density equations of state for liquid oxygen, nitrogen, argon and carbon dioxide.

The InnovaMass 240 can be loop powered with power in, a programmable analog output and a HART or MODBUS signal riding on the same two wires, and the cryogenic version of the device undergone extensive testing and field validation over the last several years.
