Abstract:
A vortex flowmeter has a vortex sensor and terminals that receive a thermal junction output from a thermowell assembly that is remote from the vortex flowmeter. The vortex flowmeter has a data input that receives data representing a thermal property of the thermowell assembly. The vortex flowmeter has a circuit that receives the first thermal junction output and the vortex sensor output, and that provides a flowmeter output that is compensated for temperature and for the thermal property.
