Max Flow; Min Flow; Max Vs M/S; Min Vs M/S - Siemens SITRANS F Operating Instructions Manual

Section 2

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

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

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 2100 m/sec.
To set the maximum Vs output range:
To activate numeric entry press
Use the numeric keys to type the 100% range for the Vs output.
To store the data press

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 400 m/sec.
To set the minimum Vs output range:
To activate numeric entry press
Use the numeric keys to type the 0% range for the Vs output.
To store data press

Max Temperature

The [Max Temperature] menu cell stores the maximum temperature range for the analog span. If
metric preferences are selected prior to site creation the temperature units will be in Centigrade. If
English preferences are selected prior to site creation the temperature units will be in Fahrenheit.
