1. SAFETY INSTRUCTIONS
1.1. The flowmeter should be mounted (dismounted) by the qualified tech-
nical staff:
- Certified for performing work of this type on the site where the flowmeter
is installed and authorized by the manufacturer
- Authorized to work with electrical installations up to 1000 V
- Upon reading all the instructions for the flowmeter and the auxiliary
equipment used for mounting and dismounting.
1.2. 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 2.5 MPa)
- Fluid temperature (up to 160 C)
- Other installation site-specific factors.
1.3. Prior to performance of works, make sure with the use of appropriate
equipment that no dangerous AC/DC voltage which may cause injury or
death is applied to pipeline section to be worked on.
1.4. In the course of mounting, start-up, commissioning and dismounting
works, it is strictly forbidden:
- To make connections to the flowmeter, switch over modes and replace
electronic components when the flowmeter is powered up
- To use defective electronic devices and electric tools or use them with-
out proper grounding.
1.5. Prior to connection of the flowmeter to the electric mains the CS module
is to be connected to the protective earthing trunk line (neutral earth-
ing).
CAUTION! Prior to connecting the protective earthing trunk
line make sure that the voltage is off.
2. MOUNTING PREPARATION
2.1. For on-site mounting of the flowmeter the following conditions should be
met:
- A free pipeline section should be available for mounting of the flow sen-
sor (CP)
- Availability of straight pipe runs of appropriate length upstream and
downstream the flow sensor
- A free pipeline section for mounting of the secondary measuring con-
verter (CS).
2.2. The flowmeter should be transported packed in the manufacturer’s box.
After the flowmeter has been moved to the mounting location from
a cold environment into a warm one (with ambient temperature above
zero), it shall be left to stand in the manufacturer’s box for at least
3 hours to make sure that no condensation remains inside.
When unpacking the flowmeter, check that the delivery package
contains all items specified in the Passport.
