4 SENSOR MOUNTING
4.1 PRESSURE SENSORS
The pressure sensors can be mounted either vertically or horizontally.
The pressure sensors are available in a choice of ranges. It is therefore important to choose the correct sensor range for the
best precision.
4.2 METER WITH PULSE EMITTER
Any pulse emitter may be connected to the D35 counter input if its electrical system has either a "Normally Open" or
"Normally Closed" contact. For setting up the pulse emitter, refer to the meter manufacturer’s instructions and the D35
instructions located in the D3500 wiring diagram.
Note:
Always connect meter last to avoid arbitrary pulse counts.
In any case you can reset the counter from the user interface.
5 D35 MOUNTING
When mounting a D35 with sensors other than those provided by CLA-VAL, be careful not to damage or deform the
housing in any way (warranty will become void).
5.1 CELLULAR NETWORK QUALITY
Check the cellular network quality at the installation location prior to installing the product.
Network strength indication from a cell phone gives initial information about reception quality on a potential installation site.
For a more detailed analysis, use the D35 configuration mode to get the exact reception quality. Refer to chapter 9.10 «
Checking the quality of the network » for more details.
Do not install: dBm  -95
The D35 configuration mode will indicate (amongst others) in dBm units, the network reception quality as seen by the D35.
Installation is not recommended below a value of -95 dBm. As the cellular network quality may fluctuate strongly across the
site, it is recommended to test at different locations.
If network quality at the installed location is not sufficient, it may be necessary to relocate the D35 or deport its antenna with
adequate CLA-VAL extension cables.
