C....130
o
C.
Note: For heat conveying liquid temperature below 90
o
C, the calculator can remain on the flow sensor or
be mounted on the wall.
For heat conveying liquid temperature above 90
o
C the calculator must be mounted on the
wall.
Connection cable length between the calculator
and the flow sensor
1,2 m
(2,5 m or 5,0 m- according to the special order)
Maximum admissible working pressure 16 bar or 25 bar.
Behavior of the meter, when the flow rate exceeds the maximum value q
s
:
- At the flow rate q
< 1,2 ∙ q
s
-linear,
- At the flow rate q
> 1,2 ∙ q
s
- constant (
q = 1,2 ∙ qs is applied to calculations of thermal energy).
The error
„Maximum allowable value of flow rate is exceeded“ is registered and duration of error is calculated.
