Technical data

16.1

Application

The measuring device is intended only for the flow measurement of liquids.
To ensure that the device remains in proper operating condition for its service life, use the
measuring device only for media against which the process-wetted materials are
sufficiently resistant.
16.2

Function and system design

Proline Prosonic Flow uses a measurement method based on the transit time difference.
The measuring system consists of a transmitter and one or two sensor sets. The
transmitter and sensor sets are mounted in physically separate locations. They are
interconnected by sensor cables.
The sensors function as sound generators and sound receivers. The sensors in a sensor pair
are always arranged opposite one another and send/receive the ultrasonic signals directly
(1-traverse positioning) →  22.
The transmitter serves to control the sensor sets, to prepare, process and evaluate the
measuring signals, and to convert the signals to the desired output variable.

Input

Direct measured variables
• Volume flow
• Flow velocity
• Sound velocity
Calculated measured variables
Mass flow
v = 0 to 15 m/s (0 to 50 ft/s)

External measured values
The measuring device has an optional interface via which an externally measured variable
(temperature) can be transmitted to the measuring device: digital input (via HART input or
Modbus)
Various pressure transmitters can be ordered from Endress+Hauser: see "Accessories"
