Design
Transmitter only as separate version
Transmitter weight: 4.4 kg (9.7 lb)
Transmitter is connected to the transducers via 3 ... 120 m
(9,8 ... 395 ft) long coaxial cables.
For ATEX versions mounted in the Ex zone
cable length is
restricted to 3m, in order to comply with specification for
electrical immunity.
Housing material Die-cast aluminum, painted
Electrical connection Cable glands: 2x M20 or 2x ½“-NPT
Transducers: 2/4x M16 or 2/4x ½" NPT
Displays and controls
Display LCD, two lines with 16 characters each (backlit)
Multi-display: 2 freely-selectable values Flow, volume, mass flow, mass, flow velocity, speed of sound,
are displayed simultaneously in two lines ultrasonic signal information, current, frequency
Operation 4 infrared keys
Hierarchical menu prompting with numbering
Power supply
Supply voltage for standard version 120...230 V AC ± 15% (50/60 Hz)
19...30 V DC/ 21...26 V AC
Supply voltage for Ex version 19...30 V DC/ 21...26 V AC
Power failure No effect for at least 1 period (> 20 ms)
Power consumption Approx. 8 VA / 6 W
