MENU 2 - FLOW RATE

The settings for total and flow rate are entirely separate. In this way, different engineering units can
be used for each e.g. cubic meters for total and liters for flow rate.

This setting is used to select the engineering unit for the indication of the
flow rate (A and B).
Alteration of the engineering unit will have consequences for operator and
setup values, they will not be automatically recalculated to the value of the
new selected unit. The K-Factor has to be adapted as well; the calculation
is not done automatically.
This setting is used to set the time unit for the flow rate calculation (A and
B). Note that the flow rate is given in engineering unit/time unit, e.g.
liters/minute (l/min).
When you change this setting, also recalculate and change the settings for
the analog rate-min and analog rate-max.
This setting is used to set the amount of digits behind the decimal point for
the flow rate indication (A and B).
This setting is used to set the K-Factor for the flow rate of flowmeter A.
With the K-Factor, the flowmeter pulse signals are converted to a quantity.
The K-Factor is based on the number of pulses generated by the flowmeter
per selected engineering unit, for example m
(more decimals, as set in decimals K-Factor) allows for a more accurate
operation of the system.
This setting is used to set the amount of digits behind the decimal point for
the K-Factor (A).
The flow rate is calculated by measuring the time between a number of
pulses, for example 10 pulses. The more pulses the more accurate the flow
rate will be. The maximum value is 255 pulses.
This setting does influence the update interval for the flowrate and thus,
indirectly the update interval of the analog output (maximum update 10
times a second). If the output response is too slow, decrease the number
of pulses. For low frequency applications (< 10Hz): do not program more
than 10 pulses, else the update time will be very slow.
For high frequency applications (> 1kHz): do program 50 or more pulses.
This setting is used to set the K-Factor for the total for flowmeter B. For
explanation see Menu 1 - TOTAL A.
This setting is used to set the amount of digits behind the decimal point for
the K-Factor (B).
This setting is used to set the K-Factor for the flow rate of flowmeter B. For
explanation see Menu 2 – FLOW RATE A.
This setting is used to set the amount of digits behind the decimal point for
the K-Factor (B).
