The density computer can be used to detect all liquid media, calculating reference density and liquid concentration and converting the values into different units such as °Brix, °Baumé and °API. Additional software modules support users in monitoring product quality, e.g. determining reference density and identifying the medium based on the measured density or concentration. EEx ia, EEx de and EEx d explosion protection approvals permit use in hazardous areas.
Advantages
Can be mounted directly on tanks and pipes for measurement without adding a pipe section
Various process connections available
Temperature compensation in combination with existing temperature measurement
No mechanical moving parts: maintenance-free, no wear and a long service life
The same density computer can also provide pump dry-running protection
The FML621 density computer can provide additional calculations, such as product quality calculations
Integrated data logger supports user operation and maintenance
