Configuration of the SA flow sensor

moneo | configure

moneo | configure is a user-friendly software package that enables easy programming and visualization of all ifm IO-Link enabled sensors (V1.0 and V1.1) as well as other manufacturers' IO-Link enabled sensors (V1.1).  The software can be downloaded here: moneo | configure.

moneo | blue

moneo | blue is an app that runs on your Apple or Android smart phones and provides access to all parameters, process values and diagnostics from all sensors connected to an IO-Link master. The Bluetooth™ adapter, EIO330, connects to one port of the IO-Link master and the app can be downloaded free of charge from the Apple App Store or from Google play.

General programming

All of ifm's process sensors, including the SA series flow sensors, use similar terminology for programming. We highlight the features used most often here. Refer to the Operating Instructions manual found under the "Downloads" tab at the product datasheet page for more details on these and other features.

Switching outputs

• Hno -- hysteresis normally open: Output turns on when the set point (SP) is reached and stays on until the flow  rate drops below the reset point (rP)
• Hnc -- hysteresis normally closed: Output turns off when the set point (SP) is reached and stays off until the flow rate drops below the reset point (rP)
• Fno -- window normally open: Output turns on when flow rate is between the high limit (FH or SP) and low limit (FL or rP)
• Fnc -- window normally closed: Output turns off when flow rate is between the high limit (FH or SP) and low limit (FL or rP)

Analog outputs

• ASP -- analog start point:  The flow rate where the analog signal equals 4 mA
• AEP -- analog end point:  The flow rate where the analog signal equals 20 mA
• MAW -- initial value of the non-scaled measuring range
• MEW -- final value of the non-scaled measuring range

The chart shows how the analog signal and display information changes when the flow rate is above / below the scaled or non-scaled measuring ranges. This feature is useful in for your process control and troubleshooting issues.

Display and indications

The SA flow sensors monitor flow and temperature, but only display one of these process values at a time. Other display indications:

1. Indication of switching status of output 1
2. Unit of measure of the various process values
3. Indication of switching status of output 2
4. 4-digit LED display of process values, parameters and parameter values
5. Up/down arrow buttons to change parameter values
6. Enter button to select parameter and confirm the setting

SA operating modes

SA series is ideal for monitoring flow of liquids and gases in pipe sizes up to 16 inch diameter, and has 3 operating modes:

• Liquid absolute mode for flow rate of water, oils and glycol in gallons per minute
• Gas absolute mode for flow rate of air in standard cubic feet per minute
• Relative mode to display flow as a percentage of the taught flow rate performed in the actual application

Use relative mode when flow rate is higher than what can be measured in absolute mode; when pipe size is 2 inch or smaller (more accurate products for these pipe sizes are available), and when the medium is something other than those specified on the datasheet.

Absolute mode for liquids and gases
Volumetric flow rate or velocity is displayed and the analog signal can be scaled as desired.

Scale the analog signal in absolute mode (output 2 only)

Relative mode
In relative mode, the sensor learns the high and low flow rates. The analog signal is automatically scaled such that the low flow rate represents 4 mA and the high flow rate represents 20 mA. The value displayed is from 0...100 % of high flow rate.
