D_COUNT([Effluent:50050],-7,7) = count of past 7 days
D_COUNT([Effluent:50050],-3,7) = count of week beginning 3 days ago
14.6.4 D_FLOW([l:p],x,y)
D_FLOW([l:p],x,y)
Daily FLOW for location and parameter, offset x months, for y days
Value: The flow value in MG/D for any location, including a process or section. The value
p is ignored (use ~).
An additional parameter z may be added to return:
1 for gal/d
2 for km3/d
3 for l/d
Examples:
D_FLOW([Effluent:~],0,0) = flow value today
D_FLOW([Effluent:~],-3,0) = flow value from 3 months ago
D_FLOW([Effluent:~],0,0,1) = flow value from today, converted to gallons per day
14.6.5 D_FWA([l:p],x)
D_FWA([l:p],x,y)
Daily Flow-Weighted Average for location and parameter, offset x days, for y days
Value: The flow-weighted average of data values of a specific location and parameter for
the date x days from the current date and extending for a range of y days. Data values
where either the parameter or the flow is BLANK are ignored. (see also: Flow-Weighted
Average in the main Synexus application)
When a parameter to calculate loading is specified (@, #, &, @@, ##, or &&parameter), a
separate flow location (and parameter) may also be specified:
add the additional parameter D_FWA([l:p],[l_flow:p_flow],x,y)
Examples:
D_FWA([Effluent:50050],-7,7) = flow-weighted average of past 7 days
D_FWA([Effluent:50050],-3,7) = flow-weighted average of week beginning 3 days ago
14.6.6 D_GAUGE([l:p],[l:p],x,y)
D_GAUGE([l:p],[l:p],x,y)
Daily GAUGE value for location and parameter, supply value from second location and
parameter, multiplier y, offset x days
Value: The value calculated from the decrease in gauge reading at a specific location and
parameter. The function uses the gauge data from the date x days from the current date,
