Flow Meter Setup

Flow Meter Setup

Flow meter installation

Attention: The Flow Meter must be configured to the pulse counter output with calibrated flow rates, which may vary between flow meter models. Please refer to the Flow Meter's Manual for more information on how to do this.

Flow Meters that use Pulse Counting Output can be connect using GPI. Pulse Counting Devices can be connected any GPI port, 1-3.

Note: Only flow meter’s pulse count outputs are supported.

1. Select “Pulse Counter” mode in mobile phone configuration app.
2. Connect COM wire to GND.
3. Connect pulse counter output to the selected GPI header connector. 



Note: Pulse Counter - a weak pullup voltage is supplied by device on the GPI input. Any transition from this pullup voltage to 0V (a pulse) will be counted. The accumulated count will be transmitted and cleared at Transmit Intervals. This input has no debounce filtering for maximum count frequency, so the input should not have any glitches. This mode is meant for open-collector type of flow meters.
