C.3 Dynamic Compensation Flow Equation

Dynamic

Compensation Flow

Equation

The Dynamic Compensation Flow Equation provides algorithms for use in determining a highly accurate PV4 flow variable for SMV 3000. Use dynamic compensation to measure liquids, gases, and steam.

Dynamic compensation flow equation compensates for:

•temperature

•pressure

•density

•discharge coefficient (gas, liquid, or steam)

•thermal expansion factor

•gas expansion factor

		NOTE: A standard flow equation is also available which uses an empirical method of
			calculation for PV4, thereby compensating only for temperature and pressure
			changes in gas and steam applications. See Subsection C.2.
	Dynamic
	Dynamic	The following pages contain three examples for configuring the SMV PV4
	Compensation	output using the Flow Compensation wizard in the SCT 3000

	Examples
	Examples	through the wizard program and enter values to configure the SMV PV4

		flow variable for a given flow application. Examples for the following
		applications are presented:
		•	Liquid Propane
		•	Air
		•	Superheated Steam
		The Dynamic Compensation Flow model wizard in the SCT 3000
		program is launched from the Equation Model page of the Flow
		Compensation Wizard.
	Example: Liquid
	Example: Liquid	An engineer has specified a SMV 3000 Smart Multivariable Transmitter
	Propane	to dynamically compensate and calculate the mass flowrate of liquid
		propane through a standard 304 SS orifice meter with flange taps. The
		engineer has sized the orifice meter to produce a differential pressure of 64
		inches H2O at 555.5 lb/m. The flowing pressure is 314.7 psia and the
		flowing temperature is 100 degrees F.

The steps in Table C-3 shows how to configure the SMV to calculate the

PV4 flow variable for this application.
