Start-Up; Measuring Flow; Evacuation - Kamstrup ULTRAFLOW 54 Technical Description

TECHNICAL DESCRIPTION
Output when using Pulse Transmitter/Pulse Divider with galvanically separated output module (Y=3)
Type Open collector. Can be connected as three-wire via the built-in pull-up resistance of 39.2 kΩ.
Diagram 17. Block diagram for galvanically separated output module (Y=3).

9.4 Start-up

16 seconds must elapse from start-up to calibration in order to allow a true reading to be reached.

9.5 Measuring flow

To obtain correct flow measurement, the duration of calibration must be minimum 2 minutes.

9.6 Evacuation

®
ULTRAFLOW must NOT be evacuated (subjected to vacuum).
