Introduction
Biotage
Liquid Level Sensor
®
Using radar technology, Biotage
the distance between the sensor (mounted on the reservoir cap)
and the liquid level, enabling the system to present the actual
amount of liquid available in the reservoir in real time.
With the liquid level sensor hub installed on your Selekt or
Selekt Enkel system, and its functionality enabled in the system
settings, the sensors can be used to monitor the liquid levels in
the solvent reservoirs and/or the waste reservoir connected to
your system (see Figure 1).
For the reservoirs to be used with the liquid level sensors, they
must be defined and calibrated in the Reservoir Administration
view. The software comes with two preconfigured reservoirs
supplied by Biotage. Custom reservoirs can be defined and
calibrated on one system and transferred to other Selekt and
Selekt Enkel systems using a USB memory device or network
share (if enabled).
Reservoirs are assigned to the solvent inlets and waste
outlet in the Solvent Setup view; see page 11. The status
of the connected liquid level sensors is displayed both in the
Solvent Setup view and the About view (see page 12).

Solvent Notifications and
Stop Limits Based on Distance
The solvent notifications and stop limits are based on the
distance between the solvent surface and the bottom of the
reservoir. This optimizes how much solvent that can be used
without the risk of aspirating air. For more information, see
page 13.
Safety Stop Limit for Waste
To ensure that the waste reservoir cannot be overfilled, the
pump operation in progress is immediately paused if the
distance between the sensor and the waste liquid becomes
smaller than allowed. This is useful if e.g. the operator by
mistake is using a waste reservoir that is smaller than the one
that has been assigned to the solvent inlet in the software.
