Use Stack DP
The SFC3332L Flow Computer allows the user to select dual DP transmitters on each meter for better
accuracy and a higher range flow. Use in conjunction with the DP Switch High % parameter setting.
DP Switch High %
The SFC332L Flow Computer will begin using the high DP when the low DP reaches the percent limit
assigned in this entry. Example: DP low was ranged from 0-25 inches and switch % was set at 95%.
When low DP reaches 23.75 in (= 0.95 * 25) the SFC332L Flow Computer will begin using the high DP
provided the high DP did not fail. When the high DP cell drops below 23.75, the Flow Computer will start
using the Low DP for measurement.
Density Type
If live density is connected to the meter, user must enter the density type. Raw density frequency or a 4-
20mA input can be selected. This density will be used to calculate mass flow and net flow.
Density
Type
Densitometer
Type 0 None
Type 1 4
–20 mA
Density 4–20 mA Type
Type 0 Specific Gravity 4-20mA
Type 1 API Gravity 4-20mA
Type 2 Density Signal 4-20mA in GM/CC
Type 2 UGC
Type 3 Sarasota
Type 4 Solartron
Type 5 UGC2
Density 4-20mA Type (Density Unit)
Note that this type of input requires the user to choose a subtype, as indicated in the table above.
Use Meter Temperature as Density Temperature
Allows the meter temperature to calculate the effect of temperature on the densitometer. Make sure the
meter and densitometer temperature are similar to avoid measurement errors.
Use Meter Pressure as Density Pressure
To allow the meter pressure to calculate the effect of pressure on the densitometer. Make sure the meter
and densitometer pressure are similar to avoid measurement errors.
Densitometer Settings - Density Period Low/High Limits
Density Period is the time period in microseconds. The densitometer fails if the density period exceeds the
density period low or high limits. If the densitometer fails and density fail code is set to 2, the maintenance
value will be used.
