● Frequency Value High = 12 kHz
● Frequency Value Low = 2 kHz
● Flow Value High = 15 kg/s
● Flow Value Low = 5 kg/s
Measured mass flow value = 7.5 kg/s (constant)
Result:
● Frequency = 4.5 kHz
Note
The connected equipment must be capable of registering the full range of frequencies
configured.

Redundancy mode (frequency)
Redundancy mode
If both channel 2 and channel 3 are configured as frequency outputs, channel 3 can be
configured for redundancy mode to follow channel 2 shifted by 90˚or 180˚. If set to redundancy
mode, channel 3 inherits all channel 2 settings. The flow direction will determine whether
channel 3 is shifted before or after channel 2 at 90° shift.
The following examples describe the frequency functionalities for channel 2 and 3 in
redundancy mode:
Channel 2 configured as positive direction and channel 3 set to redundancy mode 90°
Figure 8-3
Positive flow - channel 3 leads by 90°
Figure 8-4
Negative flow - channel 3 lags by 90°
