MultiRanger 200 and Flow Configuration AG040303 5 of 10
APPLICATION GUIDE
Section 3.0: H-Flume (P600)
Section 3.1 H-Flume Flow Rate Calculation Equation
MultiRanger 200 calculates flow rate (Q) based on Ratiometric calculation method using the following equation:
Q = Q
max
x f(H/ H
max
)/f(H
max
/ D)
Value Table
Q Flow rate calculated and displayed by MultiRanger 200. The units will not be displayed and user must
know the measurement units used (liters/sec. or gallons/min. etc.).
Q
max
Maximum flow (at maximum head H
max
) as configured in P604. Its value is user provided, and is shown
as a standalone number with no units indicated. User must know measurement units used.
For example, if maximum flow is 1000 LPS then P604 = 1000 and P606 = seconds
H
max
Maximum Head H
max
as configured in P603. Its value is provided by the user. Generally the same value
as span configured in P007. The units are defined in P005.
H Head measured by the ultrasonic head, or any other level measuring device, mounted upstream from
the open channel measuring device. IMPORTANT: set in the same units selected in P005.
D Flume height as configured in P602 in the units defined in P005. This Information will be available from
the user or by referring to the flume manufacturer’s published discharge tables (e.g. for 1.5 ft. H-Flume
set P602 to 1.5 and P005 to feet).
Section 3.2 H-Flume Configuration Table
Parameter # Description Configuration Priority
P600 Set to 3 (H-Flume device) Must be configured.
P602 Enter the value D
,
the maximum height for the flume. Must be configured.
P603 Enter the value of H
max.
Must be configured.
P604 Enter the value of Q
max.
Must be configured.
P605 Zero Head Off-set Configured only when the actual zero is
above channel zero.
P606 Time units. Must be configured.
P607 Flow rate decimal Optional, configured to display the flow rate
(Q). Factory set to 2.
P620 Low flow cut-off Optional, to avoid totalizing at flows below
this set level.
P621 Auto zero head calibration Optional, configured if displayed head has
constant off-set.
