Flow meter FC01-Ex Flow meter FC01-Ex
Operation 41 Operation 41
When the quantity-proportional pulses are assigned, the frequency of the frequency output must
no exceed 10 Hz. The limits that can be displayed are determined by the flow velocity range and
the pipe diameter.
Potential setting range of the frequency output: 1 pulse per 0.1 … 999.9 [Litre], [m
3
], [Gallons]
Behaviour of the frequency output when the max. frequency is exceeded
The max. frequency being exceeded will not cause the measurement to stop but will rather
cause the error output to signal error 60 on the display. This error is included in priority group III.
If a combination of priority III errors occurs simultaneously, they are indicated or stored in the
error memory observing the following sequence:
Error No. 20, 30, 31, 60, 40, 41.
Behaviour of the frequency output when the measurement is stopped
When the measurement is stopped (as caused by priority II error and calling the configuration or
parameter selection menus), the pulses for the quantity already counted will be available.
Thereafter the output of pulses will be stopped, with the frequency output becoming high-resis-
tive until the measurement is restarted.
Behaviour of the frequency output when the content of the totalizer is deleted
The content of the totalizer may be deleted by simultaneously pressing ▲ UP and ▼ DOWN in
the main menu
As the frequency output refers to the content of the totalizer, although its operation is not
dependent on the content of the totalizer, a totalized quantity that is smaller than that set per
pulse will not be lost.
This means that only the content of the totalizer is deleted.
5.1.1.12 Analogue output - flow rate (menu option: ANA OUT FLOW)
This menu option allows adjustment of the flow rate analogue output specifically to the requirements
of the entire system.
Options are:
* OFFSET = % (FS) (0/4 … 20 mA, 0/1 … 5 V, 0/2 … 10 V)
* ZERO = (initial value 0(20) % corresponds to a flow rate of … [m/s] [%])
* FS = (100% final value corresponds to a flow rate of …[m/s] [%])
When entering the initial value, the user should observe a reasonable resolution!
With a flow volume/time unit selected in menu DISPLAY SELECT and when setting the initial and
end values, the pertinent flow volumes will also be indicated.
When the quantity-proportional pulses are assigned, the frequency of the frequency output must
no exceed 10 Hz. The limits that can be displayed are determined by the flow velocity range and
the pipe diameter.
