Frequency outputs
In the frequency modes, the output signals will be impulses of impulse-to-gap ratio 1:1. The frequency range
available is from 1Hz to 10kHz.
Comment: The electronic unit of the meter includes only one frequency generator. It is therefore impossible
to select different frequencies for each output, or combine the fixed-frequency mode at one output with
frequency related to flow rate mode at the other output. On the other hand, the operator may select the
frequency related to flow rate mode in the positive direction at one output with that in the negative direction
at the other output, with the same frequency-to-flow-rate ratios.
Regarding the flow rate conditions, the frequency outputs can be operated in three different modes (see
below).

The fixed-frequency mode is used for servicing purposes only. The required frequency is set in Hz within the
range of 1 to 10,000 in steps of 1Hz.

Negative (non-negative) flow direction
This mode is used to identify the flow direction. In the case of negative flow direction, the output is closed
(open).

Error (no error) condition
In the case of a meter error, the output will close (open) and stay so as long as the error condition exists.
