Owner's manual for the tubemeter™
Dear customer,
we thank you for the purchase of a tubemeter™. With this highly developed USB- and
aquabus liquid level sensor you are receiving a dependable controlling device to monitor
an important system parameter of your water cooling. Changes in the liquid level can now
be detected at an early stage and failures of the system thus be prevented. In coordination
with other components a complete monitoring of your system is realisable.
The dimensions of the tubemeter™ were optimized for the usage in our aquatube™ and
aquainlet™, but an installation in many devices from other manufacturors is also possible.
The high density and modernly produced circuit board allows an installation via the USB or
aquabus connector. The used connector is automatically detected. Every component is
individually tested by us prior to shipment.
