Flow Meter FC01-LQ Flow Meter FC01-LQ
34 Configuration 34 Configuration
5.8 Pipe diameter (menu option: PIPE SIZE)
If flow volume/time unit display has been selected, it is necessary to indicate the pipe diameter
to calculate mass flow.
This is provided by selecting the pipe diameter in menu option PIPE SIZE comprising pipe
diameters from 10.0 … 999.9 mm.
5.9 Frequency output (menu option: FREQUENCY OUTPUT)
The totalizer function of the FC01-LQ has been expanded by the output of proportional quantity
pulses. The function can only be displayed by version FC01-LQ-U1T4 (transistor outputs).
The proportional quantity pulses have been determined as follow:
Example: 1 pulse / 10.0 [litre]
The frequency output will supply 1 pulse per 10 litres (totalized quantity).
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, 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-
resistive 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.
