1. An instrument for use in sensing fluid flow, comprising:

  • a flow body comprising an inlet, an outlet and a flow restrictor coupling the fluid flow from the inlet to the outlet;

    a first multisensor having a first sensing surface in the inlet that senses an inlet pressure and temperature of the fluid;

    a second multisensor having a second sensing surface in the outlet that senses an outlet pressure and temperature of the fluid; and

    a circuit that couples to the first and second multisensors, the circuit generating a fluid flow output based on outputs of the first and second multisensors, the fluid flow output including a temperature correction as a function of at least one of the sensed temperatures in the inlet and the outlet.
