DN15 Hydrus Ultrasonic Hot Water Meter
HYDRUS
The data generated by the meter can be viewed in the display loop with system
information (e.g. flow rate, volume, date, due date, medium tem- perature).
The loops are numbered from 01 to 09.
The optical button located on the front panel enables scrolling the display
loops.
To save battery lifetime, the meter switches automatically to power save mode
after 4 minutes of inactivity. The display is awakened again by pressing the
optical button.
After awakening, the display shows first a screen check (i.e. all symbols in
the display are briefly switched on and off) and then the total volume.
This remains for at least 10 seconds on the display (also when the optical
button is pressed). Afterwards the display loop can be switched with the help
of the optical button.

Pulse outputs (open drain)
| Input voltage | max. 30 V |
|---|---|
| Input current | max. 27 mA |
| Voltage drop at the active output | max. 2 V / 27 mA |
| Current through inactive output | max. 5 pA / 30 V |
| Reverse current | max. 27 mA |
| Pulse duration, pulse break, pulse frequency | depending on device |
configuration (detailed description on request)
Wiring diagram
The pulse outputs are open-drain circuits.
The drain branch has a resistance of just 0 ohm, i.e. there is no internal
current limiting. If required, this must be provided by an external protec-
tive resistance (*if not available on site).
The internal resistance of the switching device must be 5x of the protec- tive
resistance.
Cable pin assignment
The Radio/L-Bus/Pulse, Pulse/Pulse and M-Bus/Pulse/Pulse versions of the meter
are supplied with a 1.5 m 2/3/4/5-wire connecting cable with wire end
ferrules.
