9.6.4 Pipeline vibration check (at zero flow)

This check diagnoses your flow measurement installation for condition － whether it is free from external
disturbances and noises resulting from pipeline vibration or other factors.
To be successful in obtaining accurate results, run the test at zero flow.
Upon completion of the check, diagnostic results will be indicated and you will be prompted to follow the
instructions given.

(1) Bring up the item of function you want to use.
Firstly, proceed key operation to show Installation (pipeline vibration check) (zero
flow) screen.
(For the procedure to view individual items, see 9.2.2 thru 9.2.7 Transition chart.)
When the cursor is placed over pipeline vibration check (Static), click "SEL1" to bring
up pipeline vibration check (Static) (zero flow) start screen.
(2) Decide whether to activate the function or not.
If you want to run pipeline vibration check (Static) (zero flow), conduct it at zero
flow. To start Static check (zero flow), click "SEL3" to proceed to the next screen.
To exit the check process without running a check, click "ENT" and then click
"SEL3". The window returns to the menu select screen.
Click "ENT".
Click "ENT".
(3) Description of probe check function
Run pipeline vibration check (Static) (zero flow) start screen appears and count
down begins. (The check lasts in 30 seconds, approx.)
(During the check, GRN LED blinks on and off.)
(4) Diagnostic results
① Best Condition is indicated.
Top rated condition, permitting accurate and satisfactory measurement. Use the
meter in this state.
To end pipeline vibration check (Static) (zero flow) process, click "SEL3". Operation
is brought to an end and the window returns to the initial menu select screen.
Click "SEL3".
② Good Condition is indicated.
Sufficient for flow measurement. Use the meter in this state.
To end pipeline vibration check (Static) (zero flow) process, click "SEL3". Operation
is brought to an end and the window returns to the initial menu select screen.
Click "SEL3".
③ Not so Good Condition
Flow signal fluctuates. Verify influences of pump vibration or other disturbances.
To stabilize flow signal fluctuation, we suggest to select a larger damping factor for
the flow. To end pipeline vibration check (Static) (zero flow) process, click "SEL3".
Operation is brought to an end and the window returns to the initial menu select
screen.
Click "SEL3".
④ Bad Condition
Flow signal fluctuates excessively.
Inspect the pipeline for condition. (See 6.4 Piping Instructions.)
Verify influences of pump vibration or other disturbances.
To stabilize flow signal fluctuation, we suggest to select a larger damping factor for
the flow. To end pipeline vibration check (Static) (zero flow) process, click "SEL3".
Operation is brought to an end and the window returns to the initial menu select
screen.
