5 .1 .6 .4 Corrected pulse output
Figure 37 Configure corrected pulse output
On output 1 the corrected pulse output can be chosen. If used, the corrected pulse will be send
to the pulse bus, as required in proving applications (see paragraph 10).
5 .1 .7 Serial Output
There is a single non-isolated serial output on all the I/O boards. There are 3 isolated serial
outputs on both Communications boards.
A serial output can be configured to the following functions:
None No function
Modbus Slave Modbus slave for reading of Data
Modbus Master For connection to slave devices, US meter, GC etc.
Printer For Connection to a Serial Printer.
Encoder For Turbine meters with smart electronics used for Totals
CTE For communication protocol
In this volume only the modbus master will be discussed under the next paragraph. Further
details on Serial configuration including printer and report setup can be found in Volume 3.
5 .2 Stream hardware setup
When setting up a meter run, it is important to note, that there are a few basic parameters re-
quired to configure a simple run:
• Flowmeter
• Temperature
• Pressure
• Density/Specific gravity
This section will detail the hardware setup of a stream’s basic parameters.
5 .2 .1 Flowmeters
For metering principle see chapter 3.
5 .2 .1 .1 Pulse
Most meters have one or two pulse outputs (see paragraph 3.1), including:
• Turbine/Positive Displacement flowmeter sometimes also referred to as Rotary meters.
• Ultrasonic flowmeters.
