Fct. 1.2.1 FLOW UNITS for display
Select a unit in which flow rate is to be displayed from the following list
of the available units, depending on programming of Fct.1.1.1 MEAS.
INST.
For volumetric flow -
• m3/hr • m3/min • m3/Sec
• Litre/hr • Litre/min • Litre/Sec
• ft 3 /hr • ft 3 /min • ft 3 /Sec
• cft/hr • cft/min • cft/Sec
• cuft/hr • cuft/min • cuftSec
• US Gal/hr • US Gal/min • US Gal/Sec
• UK Gal/hr • UK Gal/min • UK Gal/Sec
• % MAX. FLOW
for normalized volumetric flow -
• Norm.m3/hr
• Norm. m3/min • Norm. m3/Sec
• Norm.L/hr • Norm.L/min • Norm.L/Sec
• Sft3/hr • Sft3/min • Sft3/Sec
• Scft/hr • Scft/min • Scft/Sec
• %MAX.FLOW
or mass flow -
• kg/hr
• kg/min • kg/Sec
• T/hr • T/min • T/Sec
• Lb/hr • Lb/min • Lb/Sec
• % MAX.FLOW
Note that the list is same as for Fct. 1.1.2 except for an additional unit %
MAX. FLOW (to display flow rate as a percentage of max flow).
HART: GOM 1,3,2
Fct.1.2.2 TOTAL UNITS totalizes unit for display. Totalized flow may
be displayed in one of the following units.
For volumetric flow -
• m3
• Litre • ft3
• cft • Cuft • US Gal
• UK Gal NO DISPLAY
For normalized volumetric flow –
• Norm. m3
• Norm. L • sft3
• scft • NO DISPLAY
for mass flow –
• kg • T • Lb
• NO DISPLAY
Use NO DISPLAY to exclude totaliser from display cycle.
Fct.. 1.2.3 VELO.UNITS velocity unit for display
You can choose from
• m/Sec • ft/Sec • NO DISPLAY
Select NO DISPLAY if you don't want this parameter to be displayed.
Fct. 1.2.4 FREQ UNITS frequency unit for displays
You can choose from
• Hz • kHz • NO DISPLAY
Select NO DISPLAY if you don't want this parameter to be
displayed.
Fct. 1.2.5 ERROR MSG. display of error messages.
If you want error messages to appear between display of
parameters in normal measuring mode, choose YES otherwise
select NO.
Fct. 1.2.6 CYCLE DISP. Cyclic/non-cyclic display.
YES. means display will cycle automatically. This means a
measured parameter is shown in selected units for about 6
seconds and then the next parameter in the display cycle is shown
for 6 seconds and so on. NO (non-cyclic display) means the
parameter is continuously shown on the display (to see other
parameters or to change setting use
the key). You may see
error messages in between changeover from one parameter to
next if error(s) are present and Fct. 1.2.5 ERROR MSG. is YES
Fct. 1.3.0 PULSE O/P
This submenu groups Pulse output related functions.
Fct. 1.3.1 FUNCTION P Pulse output
Choose YES to make Pulse output active as per
functions Fct. 1.3.2 to Fct. 1.3.3.NO makes Pulse
output inactive (0 Hz).
Fct. 1.3.2 RANGE P Pulse output range value
Enter a value here for the number of pulses required per unit
volume/mass. This must always be set after max flow value Fct.
1.1.2. is set.
Example –
For a value of 0.1 Kg, 10 pulses per Kg = 1 pulse per 0.1 Kg.
Pulse output programming is independent of max. flow. The
various options of units for are given below. RANGE P are given
below.
for volumetric flow –
• PULSE/m3
• PULS/litre • PULS/ft3
• PULS/cft • PULS/cuft • PULS/US.Gal
• PULS/UK.Gal
for normalized volumetric flow –
• PUL./Norm.m3 • PULS/Norm.L • PULS/Sft3
• PULS/Scft
for mass flow –
• PULS/kg • PULS/t • PULS/Lb
LIMITS - (0 TO 0.5 Hz) / Q
100%
pulse/unit volume or mass,
where Q
100%
is flowrate in Volume or Mass units per second
