Device Settings
Device settings control a number of dierent functions and
features of your device. To access the device settings, click
the gear icon ( ) next to the name of the device entry in
the device modules saved entry list or the gear in the top
right portion of the device tab. Below are explanations of
each section within these settings.
Connection
See figure 14
The connection section controls how the device commu-
nicates with Flowvision 2.0™.
Connection Settings
Connection settings is used to modify things like the device
name, port, baud rate, device ID, and the polling rate.
If port or baud rate are modified, connection to the
device is lost until it’s connected to the new port and
the baud rate is updated on the device itself.
Changing the Polling Rate modifies how often the device
information is updated. The default rate is 150ms.
Measurements
See figure 15
The Measurement section in the device settings window
allows you to adjust units of measurement, averaging,
and STP/NTP settings for an Alicat device.
Units of Measure
You can adjust the desired units for each type of measure-
ment displayed by an Alicat device. By default, only related
units of measurement are displayed in each dropdown
menu.
• Change the unit of measurement by selecting a new
unit from the dropdown menu underneath each
measurement type, and clicking Apply. The device
updates to display the new unit of measurement.
Averaging
Averaging the flow over a longer time is useful in smoothing
fluctuating readings. Values correspond to the time constant
(in milliseconds) of the averaged values. Higher numbers
generate a greater smoothing effect. The maximum
averaging time is 255 ms.
• Adjust the averaging by setting the number in
one of the Flow Avg text boxes to your desired
time in milliseconds (ms), and click Apply.
STP/NTP
If the device measures mass flow, you can adjust the STP
(Standard Temperature and Pressure) or NTP (Normal
Temperature and Pressure) values of a device to reflect a
controlled environment.
When the unit of measurement for mass flow is set to a
standardized unit, such as , the STP settings display.
However, when the unit of measurement is set to a
normalized unit such as , the settings display.
• Adjust the STP or NTP by setting the number in
the Temperature textbox to your desired value in
°C, and set the number in the Pressure text box
to your desired value in ATM. Then click Apply.
