3.10 Measurement system and applications
ROTAMASS measures the mass flow of fluids directly.
The measurement system uses the Coriolis principle and is suitable for a wide range of continuous flow
measurement applications in all branches of process technology.
ROTAMASS has two components: the detector and the converter.
The detector measures the mass flow directly and converts it into electrical signals.
The converter evaluates the electrical signals and outputs the following values:
- mass flow, independent from media properties, such as density, temperature, viscosity
- fluid density
- fluid temperature
The values are displayed and output as electrical values for use by other systems.
The converter is operated by three infra-red keys and a 4- line display and is standard equipped with HART-
communication protocol.
ROTAMASS is suitable for
-
measuring liquids, liquids with solid content, multi-phase mixtures
- measuring gases (restricted by density and pressure loss)
- simultaneous measurement of mass flow, density, temperature, volume flow and
cumulated mass and volume
- measuring of concentrations of liquid mixtures, solutions and suspensions
- connection to controllers and process control systems
ROTAMASS provides the following I/O-connections and can be configured for a wide
variety of different measurement applications (controlling, checking, monitoring, metering, mixing, filling).
- 2 active analog outputs
- 2 passive pulse outputs / status outputs
- 1 status input
optional /AP:
-
1 active pulse output / status output
optional /NM:
-
1 pulse output / status output according EN 50227 (NAMUR)
optional /KF2 :
-
1 passive analog output Ex ia
- 1 passive pulse output / status output Ex ia
These capabilities make ROTAMASS ideal for the increasing demand of requirements for automation and
the growing trend towards batch processes.
