2.2 short direct temperature sensor set
The short direct sensor can be mounted in special ball valves or in special
angle 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 also supply R½ and R¾ brass nipples which fit the short direct sensors.
The short direct sensor can also be fitted directly into all ULTRAFLOW® variants from
Kamstrup A/S with G¾ and G1 thread on the meter case. Fasten the brass unions of
the sensors lightly (approx. 4 Nm) by means of a 12 mm face wrench, and seal the
sensors with seal and wire.
3. Information codes “InFO”
MULTICAL® 601 constantly monitors a series of important functions. If a serious
error occurs in the measuring system or in the installation, an “INFO” appears in the
display and an info code can be read by activating the upper front plate button until
the measuring unit shows an “INFO” in the display. The info code is only visible
while the error exists.

both temperature sensors are outside measuring range, info code 12 will appear.
