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 CV-Log-35 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 CV-Log-35
instructions located in the CVLog3500 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 CV-LOG-35 MOUNTING
When mounting a CV-Log-35 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 CV-Log-35 configuration mode to get the exact reception quality. Refer to chapter 9.8
«Checking the quality of the network » for more details.
Do not install: dBm -95
The CV-Log-35 configuration mode will indicate (amongst others) in dBm units, the network reception quality as seen by the
CV-Log-35. 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 CV-Log-35 or deport its
antenna with adequate CLA-VAL extension cables.
