Abstract
An instrument used to control fluid flow. The instrument has a flow restrictor between an inlet and an outlet. First and second multisensor have sensing surfaces in the inlet and outlet that sense pressures and temperatures of the fluid flow. A circuit generates a mass flow output based on a difference between the pressure in the inlet and the pressure in the outlet. The mass flow output including a temperature correction as a function of at least one of the sensed temperatures in the inlet and outlet.
