Using Custom Units for PV4 Flow Measurement

The SCT contains a selection of preprogrammed engineering units that you can choose to represent your PV4 flow measurement. If you want the PV4 measurement to represent an engineering unit that is not one of the preprogrammed units stored in the SCT, you must select custom units and enter a tag that identifies the desired custom unit.

Using the SCT, selecting Custom Units allows you to choose a unit that is compatible with your application process. Additionally, a conversion factor must be calculated and entered when configuring the PV4 flow variable. This conversion factor is a value used to convert the standard units used by the SMV into the desired custom units. The standard units used by the SMV are:

•Tonnes/hour – for mass flow

•Meters3/hour – for volumetric flow

For example, to calculate the conversion factor for a volumetric flow rate of Standard Cubic Feet per Day – SCFD

For example, to calculate the conversion factor for a mass flow rate of Kilograms per day – kg/day

Conversion Factor = 24000

This factor is then entered as the Conversion Factor value in Flow Compensation Wizard of the SCT during configuration. Please note that when using the standard equation, the conversion factor, as well as other values, are used to calculate the Wizard Kuser factor. When using the dynamic corrections equation, the conversion factor is used as the Kuser factor.

Refer to the SCT on-line manual for additional information about using custom units in your SMV 3000 configuration.
