Flow measurement
The meters are provided with dynamic measuring range R100
and R250, i.e. qp = qi x 100 or qp = qi x 250. R250 is only
available for qp 1.5, 2.5, 6.0 and 15 m3 / h.

Temperature limits for the liquid
•
For flow sensors qp 2.5 m3 / h 5 ° C .... 130 ° C
•
For flow sensors qp ≥ 3.5 m3 / h 10 ° C .... 130 ° C
Note: For liquid temperature below 90 ° C, the integra-
tor can remain on the flow sensor or be mounted on the
wall. For liquid temperature above 90 ° C, the integrator
must be mounted on the wall.
Connection cable length between the integrator and the flow
sensor 1.2 m.
Maximum working pressure 16 bar (PN16).
The meter's behavior, when the flow rate exceeds the maxi-
mum flow qs:
•
Linear at flow rate up to q = 1.2 ∙ qs
•
Constant at flow rate q> 1.2 ∙ qs (q = 1.2 ∙ qs is as-
sumed for heat energy calculation).
The error message "Maximum allowable flow rate value
is exceeded" is displayed
