3. MAINTENANCE
3.1. It is recommended to check on regular basis that:
- Performance of the flow meter complies with the specifications
- Operating conditions are met
- No external defects are detected
- Electrical and mechanical parts are reliably connected.
Check periods depend on operating conditions but should not
exceed 1 month.
It is recommended to check the inside of the CP and emitting
surfaces of built-in PEAs for sediments, residue, and scale on regular
basis (the period depends on operating conditions) and clean it out from
all the deposits.
3.2. If the operating conditions specified in sections 1.2.8 and 2.1 are not
observed, this may lead to the flow meter
’s fault, or the permissible lim-
its of relative measurement error may be impaired.
External defects may also lead to deterioration in measurement
accuracy. Therefore, when the external defects are detected on the flow
meter, power cables or signal cables, contact the Service Center or re-
gional dealer for the information about the device’s operability.
3.3. Presence of display indication means that power is applied to the flow
meter, the indicated information gives an idea of the flow meter's per-
formance. The list of possible faults indicated by the flow meter is given
in section 4.3 of this manual.
Alarm (ER) situations are also indicated by status words. An ER
situation is an event characterized by mismatch of measured values
and flow meter metrological characteristics, or by impossibility of meas-
urements due to the violation of measurement conditions.
3.4. The flow meter is calibrated in accordance with the respective instruc-
tions.
3.5. Regarding the design and operating conditions, the flow meter refers to
the devices that should be repaired by authorized dealers or by the
manufacturer.
3.6. When the flow meter is sent for service, the Equipment Certificate must
be enclosed. Please specify post details, phone/fax numbers along with
the way and address for redispatching.
