1. Apparatus comprising:

  • a combination valve comprised of;

    an isolation shutoff valve configured to prevent a fluid flow;

    a check valve configured to prevent backflow and gravity circulation of the fluid flow;

    a pressure sensor configured to sense to a pressure measurement of the fluid flow and determine pressure sensor signaling containing information about a sensed pressure measurement;

    a temperature sensor configured to sense a temperature measurement of the fluid flow and determine temperature sensor signaling containing information about a sensed temperature measurement; and

    a flow measurement sensor configured to sense a flow measurement of the fluid flow and determine flow measurement signaling containing information about a sensed flow measurement;

    the pressure sensor, the temperature sensor and the flow measurement sensor all being embedded and preassembled in the combination valve with the isolation shutoff valve and the check valve as part of one integral composite unit or component, so as to form a combination isolation valve and check valve with integral flow rate, pressure and/or temperature measurement.
