Sierra Instruments launched a new cryogenic version of its InnovaMass 240 multivariable mass vortex flow meter for advanced, more reliable measurement of liquefied gases, including liquid nitrogen, liquid oxygen, liquefied natural gas, and liquefied petroleum gas, down to ā€“330F. The InnovaMass contains no moving parts that will wear out or require service. This new meter has undergone extensive testing and field validation over the last several years. Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid oxygen, nitrogen, argon, and carbon dioxide. The InnovaMass 240 can be loop-powered with ā€œpower in,ā€ a programmable analog output, and a HART or MODBUS signal riding on the same two wires. (
