Inlet prerequisites
Kamstrup’s flow sensors require neither straight inlet nor straight outlet to meet the Measuring Instruments Directive
(MID) 2014/32/EU, OIML R75:2002 and EN 1434:2015. A straight inlet section is only necessary in case of heavy flow
disturbances before the meter. It is recommended to follow the guidelines in
CEN CR 13582, Heat meter installation.
Instructions in selection, installation and use of heat meters
.
Optimal position can be obtained if you take the below installation recommendations into consideration:
A Recommended flow sensor position.
B Recommended flow sensor position.
C Unacceptable position due to risk of air build-up.
D Acceptable position in closed systems.
Unacceptable position in open systems due to risk
of air build-up in the system.
E A flow sensor ought not to be placed immediately
after a valve, with the exception of shut-off valves
(full bore ball valve type), which must be fully
open when not used for shutting off.
F A flow sensor ought not to be placed immediately
before (on the inlet side) or immediately after (on
the pressure side) a pump.
G A flow sensor ought not to be placed immediately
after a double bend in two planes.
