Installing the KMP-F
Guidelines

The present guidelines must be applied for cost calculation and execution of the installation of DanTaet leak detection systems type KMP-F.

The same guidelines apply on system commissioning for approval of the works performed.

Flow meters can be oriented horizontally or vertically, always observing Kamstrup's instructions
The two flow meters need not have the same orientation unless they will be subject to POM
(Permanent Operation Monitoring, in Danish: PDO) - ask the utility.
If the billing meter is not part of the KMP-F leakage protection system,
the meters of the KMP-F system may have arbitrary orientation.
If a flow meter is oriented horizontally, the electronics housing must be
on the side of the meter +/- 45°
Correct flow direction in the meters (arrow) must be observed
Correct placement of meters Flow/Return must be observed
Remember nipples for thermometer sleeves for large meters (by the output port).
On smaller meters (domestic billing meters), the thermometers are inserted into the meter body.
A straight pipe section (5x the meter DN) must exist ahead of the meter input port.
Any bends, nipples, and cones, must have this separation from the meter input port.
Any filter as well as the KMP-F Forward Cut-off Valve must be located
after the output port of the Forward Flow Meter.
Limiters, regulation valves etc., including pressure differential regulator
as well as the KMP-F Return Cut-off Valve and Check Valve must be located
after the output port of the Return Flow Meter.
Note when a billing meter is incorporated in the leakage detection system,
the above applies to the billing meter as well!
Electrical coupling must be ensured between the Flow and Return meters
unless a heat exchanger is installed in the immediate vicinity of the meters,
cf. Technical Description Kamstrup Multical 602, section 6.3 'Calculator with two flow sensors'
(5512-931 GB/10.2012/Rev.F1)
The system's cut-off valves must be placed at the meter output ports
with the actuators pointing upwards or sideways, but never downwards.
The Check Valve must be located in the Return pipe between the system's cut-off valve
and the stop cock.
The flow meter bodies should be left un-insulated to avoid overheating of the meter electronics.
Correct placement of cut-off valves Flow/Return (colour code Orange/Light Blue) must be observed.
