Advanced Features
Software Filter Constant Flow
[150 M 3 /Sec 2 ]
A
During normal flow conditions, there is always a non-zero acceleration component
For example, if acceleration of the flow activates the filter, the meter will assume
constant flow for the duration of the filter delay time unless the flow returns within
limits
Properly configured, this parameter will help offset excessive impacts of the filter
delay The Constant Flow parameter lets you set the acceleration limit for constant
flow
To change the Constant Flow setting, follow these steps from the Advanced menu:
1 Select Constant Flow from the Advanced menu
2 Select the desired setting
3 Press [E] to save the option and to return to the Advanced menu
Peak Detect
[0 M
3 /Sec 2 ]
A
Peak Detect offers a diagnostic view of the acceleration components observed
during flow conditions This parameter records the “high water mark” of the
measured accelerations component This value will help to properly configure the
Acceleration Factor parameter Generally, you will set the acceleration factor at about
75% of the Peak Detect measurement
To reset the Peak Detect setting, follow these steps from the Advanced menu:
1 Select Peak Detect from the Advanced menu
2 Press [+] to reset
3 Press [E] to return to the Advanced menu
MDN Filter Description This software filter operates as a Median filter This filter is very responsive and can
be used to help stabilize flow measurements This filer is enabled by selecting a non-
zero filter size Supported filter sizes are:
• S5 - Size 5
• S7 - Size 7
• S9 - Size 9
The filter technique will use the median value of the last Sx samples used for
determining flow measurement :
