Flow measurement system and method for determining at least one property of a medium

A multi-parameter flow measurement system for determining one or more physical properties of a medium, comprising:

• A. an inlet;
• B. an outlet;
• C. one or more flow tubes that connect the inlet to the outlet, the flow tubes configured to receive a medium to flow through the flow tubes;
• D. a Coriolis flow sensor in fluid communication with the flow tubes, configured to measure physical properties of the medium flowing in the flow tubes;
• E. a thermal flow sensor in fluid communication with the flow tubes, configured to measure physical properties of the medium flowing in the flow tubes;
• and
• F. a processing unit connected to the Coriolis flow sensor and to the thermal flow sensor, wherein the processing unit is configured to
• i. receive output signals from the Coriolis flow sensor and the thermal flow sensor, the output signals being representative of the physical properties of the medium measured by the Coriolis flow sensor and the thermal flow sensor;
• and
• ii. determine the thermal conductivity of the medium by plotting the output signals received from the Coriolis flow sensor and the output signals received from the thermal flow sensor against each other to generate a curve and calculating the slope of the curve, and/or
• iii. determine the specific heat capacity of the medium by plotting the output signals received from the Coriolis flow sensor and the output signals received from the thermal flow sensor against each other to generate a curve, and calculating the slope of the curve;
• and
• iv. provide a readout of the determined thermal conductivity and/or specific heat capacity.
