Measurement
Flow by measuring the transit time difference of ultrasonic signals through ultrasonic
transducers in DN 100 to 4000 2-path sensor pipes (optional, depending on selected
size, 1-path or 4-path special solutions are possible)
Nominal diameters and number of
paths
2-path DN 100 to DN 4000 (optionally also 1-path and 4-path, depending on size (DN
25 to DN 4000))
Max. cable length
120 m (395 ft) (shielded coaxial cable). For Ex version the transducer cable length is
restricted to 3 m (9.84 ft) in order to meet requirements for electrical immunity. For
2-path and 4-path systems with sizes ≥ DN 3000 cable length is restricted to 30 m
(98.4 ft).
Note
Large sizes
With nominal diameter settings above DN 3000 the deivce may not work properly.
