4.1.11 River Parameters Quadrature (RVCHID, RVI, RVHR)
The "River Channel ID" (RVCHID) is a 7 digit user definable number that should be set to uniquely
set to identify the river channel.
On-line Help
RVCHID?
River Channel ID: Fixed length 7 digit numeric field
Syntax: RVCHID<CR> Display river ch ID
RVCHID=0567890<CR> Sets ‘RVCHID’ to 0567890
The "River Increment" (RVI) parameter defines the actual mechanical or electrical resolution
expressed as millimetres of river height as well as a multiplier.
On-line Help
RVI?
River Increment: Defines the change in river height that constitutes
the recorded river height event. River height sensor
resolution in feet times the recording multiplier
Syntax: RVI<CR> Displays the river inc parameter
RVI=0.01/05<CR> Sets river height sensor resolution to 0.01
&a
mult of 5 => a river change of 0.05
= 1 event
The "River Height Reference" (RVHR) is the height from which the river height data is referenced.
(ie. The river height as read from a staff gauge during routine calibration)
On-line Help
RVHR?
River Height Reference: Ref height as set during calibration or
routine maint when using quadrature transducer,
or offset added to 4-20mA transducer level.
Syntax: RvHR<CR> Displays the river height ref level
RvHR=006.00<CR> Sets river height ref to 6
4.1.12 River Parameters 4-20mA (RVCHID, RVI, RVHR, TXR,TXI)
