Application

The measuring device is intended only for the flow measurement of liquids with a
minimum conductivity of 20 µS/cm.
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

Electromagnetic flow measurement on the basis of Faraday' s law of magnetic induction.
The device consists of a transmitter and a sensor.
Proline Promag 800 - Standard
Compact version – transmitter and sensor form a mechanical unit.
Proline Promag 800 - Advanced
Two device versions are available:
• Compact version – transmitter and sensor form a mechanical unit.
• Remote version - transmitter and sensor are mounted in separate locations.

Input

Direct measured variables
• Volume flow (proportional to induced voltage)
• Electrical conductivity
• Pressure (optional)
Typically v = 0.01 to 10 m/s (0.03 to 33 ft/s) with the specified accuracy
Electrical conductivity: ≥ 20 μS/cm for liquids in general
