2. OPERATION
2.1. Operating restrictions
2.1.1. Environmental restrictions with regard to the factors affecting the
performance and characteristics of the controlled medium shall comply
with the requirements specified in the operating documentation.
2.1.2. For precision and reliable operation, when choosing CP mounting
location, the following conditions must be met:
- Liquid pressure in the pipeline and pipeline's operational characteristics
must not be of values that may facilitate gas release and/or gas (air)
collection
- When the flow meter is operated, the PS should be fully filled with liquid.
2.1.3. Type and composition of medium (suspensions and their concentration,
impurity substances, etc.), operating mode and pipeline conditions must
not lead to corrosion and/or sediments affecting the performance and
metrological characteristics of the flow meter.
2.1.4. Lightning protection system for the site where the flow meter is located
protects the device against failures caused by lightning strokes.
2.1.5. Mounting location and operating conditions requirements specified in
this operating documentation are based on the most typical factors af-
fecting flow meter performance.
The external factors that cannot be foreseen, evaluated or tested
by the manufacturer during designing may exist or appear on site.
In this case, it is necessary to eliminate these factors or place the
flow meter in other location.
2.2. Safety instructions
2.2.1. The flow meter should only be used by the technical staff familiar with all
operating documentation for the product.
2.2.2. When working with the flow meter, the dangerous factors are as follows:
- Pipeline pressure
- Liquid temperature
- Other site-specific factors.
2.2.3. On detecting external defects on the device or damages to mains
cabling, you must remove power from the device and contact the
authorized technician for the information about the device's operability.
2.2.4. In the course of mounting, start-up or repair works you must not:
- Make connections to the flow meter, switch over modes and replace
electronic components, if the flow meter is powered up
- Remove the flow meter's components from the pipeline until pressure in
the pipeline section worked on is fully released
- Use defective electronic devices and electric tools or use them without
proper grounding (neutral earthing).
