1 Preface
This operating manual (hereinafter referred to as OM) contains the following informa-
tion: the assignment, field of application, performance capability and completeness, a prin-
ciple of operation and a design, the method of installation and commissioning, the method of
operation and maintenance service of meters.
While meters are in exploitation, it is necessary to be strictly guided by present OM.
Constantly working at functional enhancement, improvement of performance capability
and increase of meter reliability, manufacturing company SEMPAL Co LTD reserves the
right to itself to change the meter design without claiming it in present OM.
2 Assignment
2.1 Water meters SVTU-11B are intended for measurement of the water volume and
mass.
Meters also measure the volume, mass, temperature and overpressure of the water or
fluids with solid particles of no more than 200 µm and residue mass of no more than
500 mg/l (hereinafter referred to as a water).
2.2 Meters are applied for metering (including fiscal metering) of water volume accord-
ing to acting rules for the control of supply and consumption of water on industrial objects
and objects of municipal services. Functional features of meters’ configurations are given in
3.5.
3 Technical specifications
3.1 Water meters can have next configurations:
−
1 – 1-channel water meter;
−
3 – 2-channel water meter (two independent water meters);
3.2 Meters depending on their permissible error limits while measuring volume and
mass of the water are released in the following modifications:
М
1 and
М
2.
3.3 Meters of all modifications in accordance with environmental conditions meet class
С
of EN 1434 1. The meters can work under the following conditions:
−
atmospheric pressure can vary from 84.0 up to 106.7 kPa;
−
relative air humidity is up to 95 %.
3.4 Meters meet the requirements of EN 1434.
3.5 The meter consists of the following functional units:
−
flow measurement sections with ultrasonic flow sensors (FS);
−
resistive temperature detectors (R
Т
D);
−
SVTU-11B calculator.
Highest possible number of measurement channels depending on meter’s configuration
is given in the table 3.1
