6.3.2 Testing the Metering System

WARNING:
!
Contact hazards exist when the housing cover is
removed and the power is turned on !
These tasks should only be performed by trained
personnel.
Does the supply power agree with the values listed on the
converter Instrument Tag?
Are the converter and the flowmeter primary installed in the
proper locations ? (Flowmeter primary, Protection Class,
converter, temperature, vibration, cable length, cable type,
display indication in the correct flow direction) .
Does the wiring agree with the specifications in the
Interconnection Diagrams ?
Is the flowmeter primary correctly grounded?
Is the supply voltage value at terminals L & N within the
nominal voltage limits of +10/-10 % ?.
Is the flowmeter primary filled with fluid?
Is switch S901 on the connection board correctly set for the
flowmeter primary type and size?
Turn on the power. Does the display indicate 0 % ? Is the
correct flow direction indication
reverse displayed in the 1st line ?
For continuous flow has the Standard operating mode been
selected ? For pulsating flows has the Piston Pump
operating mode been selected?
Have the meter size, engineering units, flow range,
density, pulse factor etc. been entered?
Does the present flowrate value agree with the displayed
value and the output signals?
The metering system is operational. Store the meter
location parameters in the external EEPROM. The meter
location parameters can also be recorded on the page 52 in
the Overview Page for future reference.
1) If the flow direction does not agree with the flow direction indicators in the display, then the flow direction indicators are b e reversed.
Select the "Flow Direction" parameter in the "Operating Mode" submenu" and change accordingly.

No Solder correct jumpers for the required voltage,
see Fig.20.
No Check allowable installation conditions, temperature
(insulate high temperature design flowmeter primary and
pipeline), Protection Class, vibration.
No Check the connections per the Interconnection Diagrams
beginning on Page 7.
No Check the grounds per the Interconnection Diagram, also
see the Flowmeter Primary Instruction Bulletin.
No Provide supply voltage within the limits.
No Fill pipeline.
No See Figs.18-20. Switch S901 is open for use with flowmeter
primaries 10DS2110/3110. Switch S901 closed for use with
flowmeter primaries 10DI1425 ≥ 20" [DN 500], 10DS3111A/
..B/..C ≥ 20" [DN 500] and 10D1422 1/8"- 40" [DN3 to 1000].
No Adjust system zero according to instructions in 3.2. Check if
the flow direction indicators agree with the flow direction
Fuse defective ? Conductivity too low ? To check see
Flowmeter Primary Instruction Bulletin.
No Select the parameter Standard or Piston Pump in the
operating mode submenu. Turn on software filter, set
damping >2.4 sec.
No Enter meter size, units and flow range, select current output
e.g. 0-20/4-20 mA.
No If the flow indication and current output are noisy a software
filter can be turned on or the damping setting increased.
Conduct Function Test 5.4 or check converter with
Flowmeter Primary Simulator 6.2 .
