Zero point instability
Start
Check instrument grounded
case,The grounding ring and
the grounding wire is
connected?
Good grounding?
Conductivity of liquid is
volatile?
The conductivity is lower
than 20µs/cm
Flowmeter is near the
motor, transformers?
and use of public land
to those equipment ?
Suspected insulation problem in
flowmeter, contact with manufacturers
Fully shielded instrumentation
flowmeters should far from these
devices.
Independence grounding facilities
Remove sludge and scale on the
electrode and near side.
Install meters to vertical
1To ensure that changes in the scope of the
conductivity of the liquid does not exceed the
scope of permissible;
2)Pls don’t apply instrument in this situation
for conductivity lower than 20 µs/cm
In accordance with the(sensor Manual)
correctly grounded
(Grounding resistance of less than 10Ω)
change valve
In the instrument on the downstream side of
pipe to open a pore, it is easy to be able to
find whether there is any air bubbles;
particular attention to the level of the
installation of the instrument to change the
install location or change the flow of upward
vertical installation in order to fluid filled
sensor tube
