Mass Flow Flowmeters

For compressible fluid applications (i.e. steam and gases), multivariable differential pressure flowmeters are ideal. These flowmeters shall perform real-time calculations by compensating for changes in the COP flow coefficient (Cd) factor, gas expansion factor, velocity of approach factor, density or compressibility, viscosity, and Reynolds Number.

When a multivariable transmitter is integrated with the COP, the flowmeter shall perform within ±0.7% to ±0.9% of mass flow rate in gas and steam. The vendor shall make independent testing documentation available demonstrating this performance.

Functional Specifications

•	The flowmeter shall provide a fully
	compensated mass flow output.
•	The flowmeter shall have the capability of
	either a Gage Pressure (GP) sensor or an

•The pressure instrument shall perform continuous diagnostics, capable of self-test functions and be able to provide specific diagnostic information.

•Basic configuration capabilities of the pressure instrument shall allow the user the ability to input and store information including the range, engineering units, damping, drain / vent valves, flange, and O-ring materials, date, message, descriptor, tag number, and serial number.

•Mass flow configuration shall allow the user to input and store information including the fluid name, fluid density, fluid viscosity and the COP primary element calibration factor.

To calculate mass flow, the transmitter shall utilize the full DP mass flow equation:

Absolute Pressure (AP) sensor.

• The pressure instrument shall be two-wire,

multivariable (differential pressure, pressure,

and temperature).

Qm = NCdEY1 d2 {DP(ρ)}

Software Specifications

•Pressure Instrument outputs shall be a 4-20 mA analog signal, user-selectable to represent mass flow, differential pressure, static

pressure, or temperature, with a superimposed digital signal, using HART® protocol.
