This document summarizes a density and mass flow processor from SCIAM. The processor takes density and volumetric flow signals from a DM3 transmitter and flow meter to calculate and output mass flow rate. It provides a digital display and outputs for totalized mass and flow rate. The processor also logs data, connects to software via Ethernet, and has programmable alarms and settings.

1. Density & Mass Flow Processor
SCIAM offers a processor which is designed to take the 4 – 20 mA outputs from a DM3
Transmitter and flow signal from a volumetric flow meter. SCIAM recommends only volumetric
flow meters known to have an acceptably low signal to media noise ratio. Magnetic flow
meters with correct liners and grounding, suitable for mining,
dredging and similar slurries are recommended.
The processor accurately multiplies the density and volumetric
flow signals to provide a 4 – 20 mA output proportional to mass
flow rate. It is then programmable using 4 push buttons on the
front panel to provide a digital display, record and outputs for
wet or dry totalized mass flow and mass flow rate, wet density
or wet sg, or % dry solids.
The processor also has the capability to log data to an internal
memory, removable memory and connects to ‘Historian’
software via Ethernet. Settings for alarms and alerts are also
programmable using the processor.
