2. OPERATION
2.1. Operating restrictions
2.1.1. Environmental restrictions with regard to the factors affecting the per-
formance 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 loca-
tion, 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 flowmeter 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 flowmeter.
2.1.4. Lightning protection system for the site where the flowmeter is located
(complying with "Guidelines on lightning protection of buildings, con-
structions and industrial pipelines" SO153-34.21.122-2003) 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 flowmeter 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
flowmeter in other location.
2.2. Safety instructions
2.2.1. The flowmeter should only be used by the technical staff familiar with all
operating documentation for the product.
2.2.2. When putting the product into operation and during operation, "Rules for
Operating Electrical Systems By Consumers" and “Interbranch Rules
for Labor Safety (Safety Rules) When Operating Electrical Systems"
must be observed.
2.2.3. When working with the flowmeter, the dangerous factors are as follows:
- AC voltage (RMS value up to 264 V, frequency 50 Hz)
- Pipeline pressure (up to 1.6 MPa)
- Other site-specific factors.
2.2.4. On detecting external defects on the device or damages to mains ca-
bling, you must remove power from the device and contact the author-
ized technician for the information about the device's operability.
2.2.5. In the course of mounting, start-up or repair works you must not:
- Make connections to the flowmeter, switch over modes and replace
electronic components, if the flowmeter is powered up
