Operation
Establish flow through the LFE. Measure t h e differential pressure between high pressure sensing
port and low pressure sensing port. Measure t h e inlet gas temperature. For standard or mass flow
rates, measure absolute line pressure. Refer to calibration curve/table instructions for flow rate
calculations.
