5.3.3 Analog
outputs
The following 3 analog outputs are available as options:
0 ... 10 V
0 ... 20 mA
4 ... 20 mA
The previously set measuring rate (see section 5.3.1) is used for the analog interfaces.
Additional signal-processing units can be connected to the analog outputs, e.g.:
• A recorder
• An oscilloscope
• A transient recorder
• A process computer
• A
controller
This makes it possible to visualize and record rapidly changing flowrates.
The Sensyflow FMT700-P measuring system has been specially developed for applications that
call for a rapid response time where changes in flowrate are concerned. Fig. 15 illustrates the
high speed of the measuring signal response when a throttle valve opens compared with the
sluggish behavior associated with a orifice plate.
