2 FLOWRATE
2.1 UNIT Determines the measurement unit for the flowrate. The type of unit that can
be selected depends on the flowmeter unit (volumetric or mass) selected in
4.2: FLOWMETER > UNITS
.
The following can be selected:
AUTO-VOL: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL - nm3 - scf
AUTO-MAS: mg - g - kg - ton - lb - US ton
Hand: mL - L - m3 - US GAL - I GAL - cf - Oil bbl - nL - nm3 - scf - mg - g -
kg - ton - lb - US ton - rev - P - (no unit)
2.2 TIME Determines the time interval (sec, min, hour or day) for calculating the
flowrate.
2.3 DECIMALS Determines the number of decimals for the flowrate.
2.4 K-FACTOR
This value is used to convert the flowmeter pulse signals to a flowrate unit.
The
K-factor is based on the number of pulses generated by the flowmeter
per measurement unit selected in
2.1: FLOWRATE > UNIT
.
The more accurate the K-factor , the more accurate the system.
This setting can only be changed if the automatic unit conversion in
4.2: FLOWMETER > UNITS
is set to Hand. Otherwise, K-factor conversion will be
Auto.
After pressing PROG, the decimal point will start to flash. The decimal
position can then be changed by pressing the SELECT-key, then press the
CLEAR key to set the digits.
2.5 FILTER
Stabilizes the flowrate reading. This digital filter setting produces a more
stable but less actual reading. The filter principal is based on three input
values: the filter level (01-99), the last calculated flowrate, and the last
average value.
The higher the filter level, the longer the response time of a changed value.
Use trial and error to find the best setting for your application.
2.6 PERIOD This value is used to calculate the flowrate by counting the number of
pulses within a certain time, for example 1 second. The longer the time, the
more accurate the flowrate.
●
This setting directly influences the update time for the analog output. If
the output response is too slow, decrease the number of pulses.
●
The shorter the update time, the higher the power consumption of the
unit (important for battery‑powered applications).
5.5.3 MENU 3: DISPLAY
3 DISPLAY
3.1 FUNCTION Determines which information is shown on the main screen.
●
Total : Total is displayed with the large 12 mm (0.47”) digits; Flowrate is
displayed with the 7 mm (0.28”) digits simultaneously.
●
Flowrate : Only Flowrate is displayed with the large 12 mm (0.47”) digits
together with the measuring unit.
●
Accumulated total : Total is displayed with the large digits; Accumulated
total is displayed with the small digits simultaneously.
When SELECT is pressed on the main screen, the operator can scroll
through the various process values. See
Section 4: Operation [»9]
for more
information on operator information and functions.
