Level Input Parameters; Analog Output Parameters - Accusonic 8510+ series Reference Manual

Level Input Parameters

Either one or two can be allocated to a section. The allocation is defined in the Section menu.
Level parameters are ignored by the system when in "Pipe" mode.
Scaling for each individual analog level input is defined by the following parameters.
MIN mA INPUT
4mA LEVEL INPUT
20mA LEVEL INPUT
LEVEL RESISTOR
LEVEL FILTER 0-4

Analog Output Parameters

Any number up to four analog outputs can be allocated to a section. The allocation to the section, the
variable to be output and the scaling for each individual analog output are defined by the following
parameters.
ASSIGN A SECTION
F / L / V / T / SF {0-4}
4mA OUTPUT
20mA OUTPUT
OVERRIDE OUTPUT?
The value of the input in mA below which it is declared to be in a fault state.
The value may be in the range 0.0 to 19.0 mA.
Elevation of the water surface above the site datum, at which the Level input
is 4.0 mA.
The value may be in the range –5000 to +5000.
Elevation of the water surface, above the site datum, at which the Level input is 20.0
mA.
The value may be in the range –5000 to +5000.
The value of the input resistance of the 4-20 mA Level input.
The value may be in the range 150 to 50.
Standard value is 100.
This parameter is set at the factory to calibrate the input.
This value can be changed to calibrate the input,as necessary.
The approximate time in units of 15 measurement cycles, over which the Level data
are averaged. e.g.: if set to 0 no averaging; if set to 4 (max) averaged over 60
measurement cycles.
Applies to the data displayed, used in the computation of flow, logged and output
on the analog output.
Defines which section the output responds to.
For "sum of section" flow, set to 0.
For Section 1, set to 1, etc.
Selects the variable to be represented by the analog output.
Set to 0 to output flow for the section.
Set to 1 to output the arbitrated value of the level for the section.
Set to 2 to output the average velocity for the section.
Set to 3 to output Temperature, in F for English or C for metric units.
Set to 4 to output the Sum of the Section Flows.
Note. The units of velocity are either ft/s or m/s depending on the parameter
English/metric. Velocity output is not affected by the Flow Scaling.
The velocity is equal to the flow divided by the wetted cross section area.
The value of the variable, in the units specified, for which an output of 4.00 mA is
required.
The value of the variable, in the units specified, for which an output of 20.00 mA is
required.
Selects whether the output is to be derived from the variable or from a manually
