1 Introduction
1.1 Instrument description
The 849 Level Control is used for monitoring liquid levels in canisters and
bottles. It can detect both high liquid levels (e.g. warning of overflow of a
waste container) as well as low liquid levels (e.g. a supply container run-
ning empty). Due to conductivity measurement the level sensors can be
used in various media.
The sensor signal is detected by the 849 Level Control and is forwarded as
signal level to a remote connection of a Metrohm automation system.
Therefore, the 849 Level Control can be used with all Metrohm systems in
which the scanning of remote lines is possible (SCAN command).
1.2 Model versions
The 849 Level Control is available as three model versions:
2.849.0010
849 Level Control with sensor, comprised of three steel rods (stainless
steel, non-acid-resistant, 35 cm long).
For aqueous media.
2.849.0020
849 Level Control with sensor, comprised of three metal-free rods (mate-
rial: carbon fiber compound, 35 cm long, unbreakable)
For eluents in chromatography. Can be used in 6.1621.000 20 L canisters.
Also integrated into the screw cap are two FEP tubes for aspirating or fill-
ing the container.
2.849.0030
849 Level Control with sensor, comprised of three metal-free rods (mate-
rial: high-purity graphite).
For eluents and ultra pure water in chromatography.
Standard length 25 cm for 2 L bottles. The sensor rods can be shortened
to the required lengths suitable for 1 L or 0.25 L bottles (predetermined
breaking points).
Also integrated into the screw cap are two FEP tubes for aspirating or fill-
ing the container.
