Vfo

The minimum and maximum flow rate entries establish the Vfo span.

 

 

Spanned Volumetric

The [Max Flow] menu cell sets 100% of span. The [Min Flow] menu cell

 

 

Flow Rate:

sets 0% of span. Use signed numbers for bi-directional spanning. Note

 

 

 

that negative (reverse) flow always is lower than positive flow, whatever

 

 

 

its absolute magnitude. For example, for a flow measurement range of -

 

 

 

30 GPM to +10 GPM, the 4 mA span will be -30 GPM, and the 20 mA

 

 

 

span will be +10 GPM.

 

 

 

 

 

 

Vfab

Vfab is the absolute magnitude of the volumetric flow rate (Vfo). There

 

 

Spanned Absolute

are no menu cells provided to span this output. Vfab shares the Vfo

 

 

Volumetric Flow Rate:

span entries. The Vfab minimum span is always zero. The maximum

 

 

 

span for Vfab is the largest absolute value of either the min. or the max.

 

 

 

flow rate (Vfo) entries. For example, a span between +10 GPM and -30

 

 

 

GPM, spans the Vfab output from 0 GPM to 30 GPM.

 

 

 

 

 

 

Vs

Vs is the sonic velocity in meters-per-second (m/s) of the flowing liquid.

 

 

Spanned Liquid

The min. and max. Vs entries establish the Vs span. Max Vs (m/s)

 

 

Sonic Velocity:

defines 100% of span. The Min Vs (m/s) defines 0% of span.

 

 

 

 

Maximum span values represent:

Minimum span values represent:

100% of span

0% of span

Current output of 20 mA

Current output of 4 mA

Voltage output of 10 Vdc

Voltage output of 0 Vdc

Pulse output of 5000 Hz

Pulse output of 0 Hz

Max Flow

 

The [Max Flow] menu cell stores the maximum range for the flow rate output (Vfo). It can be a positive or negative value. Enter the data using the flow rate units you selected. This entry also spans the unsigned flow variable (Vfab).

To enter the Max. Flow Range Setting:

To activate numeric entry press

Use the numeric keys to type the maximum flow rate (100% of range).

To store the data press ENT

Min Flow

The [Min Flow] menu cell stores the minimum range for the flow rate output (Vo). It can be a positive or negative value (to reflect bi-directional flow). However, the minimum span for the unsigned flow (Vfab) is always zero. Enter the data using the flow rate units you selected.

To set the Min. Flow Range:

To activate numeric entry press

Use the numeric keys to type the minimum flow rate (0% of range). To store data press ENT

The following Span Data items are set in the same way as the two previously shown examples by entering numeric values and storing the data.
