If motors and / or valves are to be switched with the flow meter,
a switching amplifier (FSV) is needed.
The use of the electronic analysis unit FLUXTRONIC
it is necessary to select a signal interface permitted in hazardous areas. This is not the
case with all available switching amplifiers. The NAMUR* interface is a proven one and
meets all of the above requirements. (* NAMUR = Normenausschuss Mess- und Regel-
technik / committee for measuring and control techniques in the chemical industry)
If you are using your own switching amplifier, it is imperative that you
note the certificates of conformity of the display electronics and the
switching amplifier you are using.
The switching amplifier and the external units connected to it should
only be installed, operated and serviced by trained and qualified per-
