2.2 short direct temperature sensor pair
The short direct sensors can be mounted in special ball valves or in special tee-
pipes, both with threads up to R1 and built-in M10 union for the short direct sensor.
For mounting in existing heating installations with standard angle tees Kamstrup
A/S can, furthermore, supply R½ and R¾ brass nipples fitting the short direct
sensors.
The short direct sensor can also be fitted directly into all Kamstrup's ULTRAFLOW®
variants with G¾ and G1 thread on the meter case. Fasten the sensors' brass
unions lightly (approx. 4 Nm) using a 12 mm face wrench and seal the sensors with
seal and locking wire.
3. Mounting of flow sensor
Prior to installation of the flow sensor, the system should be flushed and protection
plugs/plastic diaphragms removed from the flow sensor.
Correct flow sensor position (flow or return) appears from the front label of
MULTICAL® 602. The flow direction is indicated by an arrow on the side of the flow
sensor.

Straight inlet: ULTRAFLOW® requires neither straight inlet nor straight outlet to meet
the Measuring Instruments Directive (MID) 2004/22/ EC, OIML R75:2002 and EN
1434:2007. A straight inlet section will only be necessary in case of heavy flow
disturbances before the sensor. We recommend to follow the guidelines of CEN CR
13582.
