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) as noted above.
To enter the Max Flow range setting:
1. Press the <Right Arrow> to activate numeric entry.
2. Use the numeric keys to type the maximum flow rate (100% of range).
3. Press <ENT> to store the data.
Min Flow
The [Min Flow] menu cell stores the minimum range for the flow rate output (Vfo). 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:
1. Press the <Right Arrow> to activate numeric entry.
2. Use the numeric keys to type the minimum flow rate (0% of range).
3. Press <ENT> to store data.
The following Span Data items are set in the same way as the previously shown examples by
entering numeric values and storing the data.
The Max Flow2 and Min Flow2 outputs provide a second independently spanned output that
can be used for improved I/O resolution when high turndown ratio is required.
Max Flow2
The [Max Flow2] 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.
Min Flow2
The [Min Flow2] menu cell stores the minimum 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.
Max Vs m/s
The [Max Vs m/s] menu cell stores the maximum range for the sonic velocity output. The sonic
velocity (Vs) appears on the Stripchart display and can drive any analog output or the alarm
relay. The [Max Vs m/s] menu cell restricts this parameter to a maximum range of 1500 m/sec.
to store the data.
Min Vs m/s
The [Min Vs m/s] menu cell stores the minimum range value for the sonic velocity output. The
sonic velocity (Vs) can be displayed on the Stripchart and drive any analog output or the alarm
relay. The [Min Vs m/s] menu cell restricts this parameter to a minimum range of 0 m/sec.
Max S.G.
The [Max S.G.] menu cell stores the maximum range value for the specific gravity output. The
specific gravity appears on the Stripchart display and can drive any analog output or alarm
relay. The [Max S.G.] menu cell restricts this parameter to a maximum range of 100.
