flow in the pipe. The additional

CHECK INSTALL

error (flow rate = 0.0 or some steady or fluctuating
value) is an indication of :

improper / inadequate earthing

·

·

·

·

·

·

excessive pipe vibration

SYMPTOM :

Flowrate indicated is 0.0 even with

flow in the pipe.

Vortex sensor cable disconnected or not properly

connected.

Flow sensor faulty - some checks are given in

Sect. 7.1.1

SYMPTOM :

Fatal error

INV.CONFIG

(invalid

configuration)

Configuration data in the non-volatile memory is

inadvertently corrupted. Go to the programming
mode and recheck (reprogram, if necessary) all
the settings. If error persists contact KHRONE
MARSHALL service.

SYMPTOM :

Display contrast is progressively

fading.

Never expose display directly to the sunlight !

·

·

·

·

·

·

·

·

Install a sunshade if necessary.

SYMPTOM :

Flow indicated responds to changes

in flow but indicated value does not correspond to
actual flow rate. Also ‘CHECK INST.’ error may
be appearing intermittantly.

Check programming of

Fct. 3.1.2 K-Factor

which should be same as on the name plate

Meter not properly centered on the pipeline The

axis of meter bore should be aligned with that of
pipe.

Gasket at the meter are protruding into pipe bore.

Gaskets must not project into effective cross
section of the pipe.

Irregularities on the surface of the pipe bore.

The pipe bore should be free from irregularities
at the welded joints, dirt, deposits and excessive
surface roughness.

Vortex signal is falsified due to a bi-phase

medium. Bi-phase media are not permitted. Use a
moisture separator for wet steam applications to
remove moisture droplets from the steam. Use
suitable filters in gas applications to remove solid
particles from the flowing gas.

Incorrect angular position of the meter

Refer to Sect. 2.1 (I) for allowable mounting
positions.

Insufficient upstream / downstream pipe lengths.

Check that upstream / downstream pipe lengths
are of correct minimum length as given in
Sect. 2.1 (3).

Check the flow direction and direction of arrow

on the primary .
