Installation conditions
No special measures such as supports are necessary. External forces are absorbed by the
construction of the device.
6.1.1
Mounting position
Mounting location
The measuring device is usually installed in a bypass line. If flow rates are low, the device can
also be installed in the main pipe.
Installation in a bypass line is recommended in the following cases:
• Flow rate >1 l/min (0.26 gal/min.)
• Pipeline diameter >6 mm (0.24 in)
Orientation
The orientation of the device does not affect the measuring accuracy.
Flow direction
The flow direction does not affect the measuring accuracy.
Inlet and outlet runs
Inlet and outlet runs do not affect the measuring accuracy.
6.1.2
Requirements from environment and process
Ambient temperature range
• If operating via USB port: operating temperature is limited to 0 to 60 °C (32 to 140 °F).
• If operating outdoors: avoid direct sunlight, particularly in warm climatic regions.
System pressure
The relative accuracy of the density measurement increases with increasing system
pressure.
Filter
To prevent the micro-channel from clogging, it is advisable to install a filter upstream from
the measuring device. The filter is included in the delivery.
• Recommended filter pore size:
