1. DESCRIPTION AND OPERATION
1.1. Purpose and application
KARAT-520 ultrasonic flowmeters are designed for industrial and
commercial metering of volume flow and liquid volume in filled pipe-
lines of heating systems, cold and hot water supply under conditions
of round-the-clock service. The flowmeters can be used as a part of
heat meters or measuring systems.
1.2. Design version
Flowmeters are
devices
which measure flow rate and volume.
The present devices are produced in accordance with technical re-
quirements TR 4213-009-32277111-2012.
As for design the flowmeters differ in nominal diameter, power supply
type, output signals type (or types combination), construction of mo-
unting elements.
