Figure 7-3 Effect of flow direction on milliamp outputs: 4 mA value = 0
Volume flow type Liquid • Select the desired volume flow type.
- If you select Liquid, only liquid volume units are available for measurement
- If you select Gas, only gas standard volume units are available for
measurement. See the section entitled Gas standard volume flow and
standard density.
• If you are using the enhanced density application or the petroleum
measurement application, select Liquid.
Volume units
(1)
l/s • Select the desired unit of liquid volume flow. See Table 7-5. The liquid
volume totalizer and inventory will use the corresponding volume unit.
Volume low flow
cutoff
(1)
0.00000 l/s • Enter the liquid volume flow rate below which volume flow outputs and
displays will indicate zero flow. See the section entitled Cutoffs later in this
chapter.
• Milliamp outputs have an additional cutoff parameter. See Section 8.4.4.
Standard gas volume
units
(2)
SCFM • Select the desired unit of gas standard volume flow. See Table 7-6. The gas
standard totalizer and inventory will use the corresponding volume unit.
Standard gas volume
cutoff
(3)(2)
0.0000 SCFM • Enter the volume flow rate below which volume flow outputs and displays will
indicate zero flow. See the section entitled Cutoffs later in this chapter.
• Milliamp outputs have an additional cutoff parameter. See Section 8.4.4.
Standard gas density
(2)
0.10000 g/cm

• Enter the standard density of the gas you are measuring. See the section
entitled Gas standard volume flow and standard density
(1) Displayed only if Volume Flow Type = Liquid.
(2) Displayed only if Volume Flow Type = Gas Standard.
(3) Available only on systems with the enhanced core processor.
