After selecting the frequency setting, the maximum frequency of 1 kHz will be generated when the upper-
range value for mass or volume flow is reached (depending on the selected pulse unit). If the flow rate
falls below the low flow volume, the actual frequency is 0 Hz.
After selecting the pulse setting, pulse value and unit, the transmitter will determine the number of pulses
per flow volume. When choosing a combination of these settings that cannot be fulfilled in real time for
the upper-range value (e.g. the number of pulses per time unit cannot be generated due to the pulse
width which is too large), the error message “Pulse width too large” or “Inconsistent parameter” will be
displayed.
Press
↵ to display the current setting:
Output of
[Pulses]
According to the description in Section 12.4.3.1 Selection window/make a selection, the operator can
toggle between frequency and pulse output (default setting).
13.8.2 Pulse output unit
This function allows the operator to define the unit to be counted. After selecting the Pulse output unit
function, press
↵ to display the following selection field:
Accumulation of
1.0 kg
The current value will be displayed. As mentioned in Section 12.4.3.2 Input window/modify a value, the
operator can choose between the following units:
Mass units:
g, kg, t, lbs, ston, lton
Volume units
m³, l, USG, UKG, USB, ft³, acft
13.8.3 Pulse value
This function allows the operator to define how many pulses will be output per unit counted. After select-
ing the Pulse value function, press
↵ to display the current unit:
1 pulse per
[1.0] unit
As mentioned in Section 12.4.3.1 Selection window/make a selection, the operator can choose between
the following pulse values:
Values: 0.001, 0.01, 0.1, 1.0, 10.0, 100.0
