Liquid level sensor and dehydration cylinder strainer

Liquid level sensor, concentration detection sensor, concentration detection
sensor air filter, and retort filter.

The retort is equipped with 3 ultrasonic level sensors and one concentration
detection sensor: the first and second level sensors (Figure 12-1) are used to
detect the height of the reagent level during dehydration, the third liquid level
sensor (Figure 12-2) is used to monitor overflow risk. When the liquid level
sensor 3 detects a liquid signal, the system automatically stops working to
prevent the liquid from entering the gas system and causing a failure. The
concentration detection sensor (Figure 12-3)is used to detect the concentration
of reagents in the process of dehydration. An dust proof net is installed outside
the concentration detection sensor (Figure 12-4) to prevent human error
contact of the sensor probe and make it invalid.

The bottom of the retort has a filter (Figure 12-5), which is locked by a
custom-made bolt, there is a “-” spanner on the top of the bolt, turning the bolt
counterclockwise with spanner to remove the filter.

On HP300 Plus model, the retort is with grinding and polishing process,
which can make the retort not easy to remain paraffin wax and other
impurities, and easy to clean.

Concentration monitoring

When adding or replacing ethanol, set the initial reagent concentration value. During the
operation of the equipment, the density meter will always monitor the concentration of
ethanol, and the measured liquid concentration can be visually displayed on the screen
to facilitate understanding of the reagent status; in addition, combined with the actual
