DIEHL DN 50.200 Hydrus Ultrasonic Cold and Hot Water Meter
WHAT IS INCLUDE
INSTALLATION
CAUTION
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 temperature). 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 μA / 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 protective resistance (*if not available on site). The internal resistance of the switching device must be 5x of the protective 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.

Never connect the external M-Bus to the pulse output of the meter! It will destroy the pulse output and lead to the loss of all factory warranty claims.
Radio specifications
| Sending intervals | Every 14 … 256 seconds (variable, according to 0.1 duty cycle (min. 14 seconds); depending on protocol length and programming) |
| 434 MHz frequency band | Transmission power (EN 300 220-2 V3.2.1): 10 mW e.r.p. |
| 868 MHz frequency band | Transmission power (EN 300 220-2 V3.2.1): 25 mW e.r.p |
Venting
In the event that complete venting of the meter is not possible, please install the meter at an angle of 45°!
