Order code for "Sensor version":
• Option SB "Bidirectional" measures the flow in both directions
(»positive« and »negative« flow) and totalizes the flow in both directions. The device is
calibrated in both directions.
• Option SC "Reverse flow detection" only measures the flow in the positive direction. The
reverse flow is detected by the device but is not totalized. The device is only calibrated in
the positive forward flow direction.
Order code for "Application package":
Option EV "Second gas group" enables the configuration of two different standard
gases/gas mixtures in the device and allows the user to switch from one gas group to
another using the status input or (if available) via bus communication.
Measuring range The available measuring range depends on the choice of gas and size of the pipe. Each
measuring device is calibrated individually with air under reference operating conditions.
No recalibration is required in the case of customer-specific gases, as the device's Gas
Engine functionality converts from air to these gases.
The measuring ranges calibrated for air are indicated in the following section. For
information on other gases and process conditions, contact your sales organization or use
the Applicator selection software.
