Manual Integrator Supercal 531 06-06-2011 54
basic configuration minimum values
precision 1 % 1 %
minimum period 5 sec. (10 sec. battery-operated) 5 sec. (10 sec. battery-operated)
maximum period 200 sec. 5 sec.
For specific applications, the minimal values of the holding time are reduced:
Minimum holding time: 1 second
Maximum holding time: 2 seconds
Attention:
When configuring the parameter of the maximum holding time, attention has to be paid that this
value is higher than the duration between two volume pulses at mean flow of the connected flow
sensor. Otherwise the displayed flow and the displayed performance will be zero.
The maximum holding time always has to be adjusted specifically to the application. If, later, the
heat meter is integrated into a controller application, it is important to check the setting of the
maximum holding time.
8.2.4 The „cut off“- function of the Superstatic 440
When combining the integrator Supercal 531 with the static flow sensor Superstatic 440, the possi-
ble flow measuring range is set and limited by a lower and upper threshold value („cut off“ and
„flow saturation“) at the factory.
The „cut off“- function can only be integrated in the calibration- and measuring-relevant
part of the Supercal 531 by damaging the calibration seal.
As soon as the flow drops below the set „cut off“, flow measurements are no longer carried out.
Thus also the volume is no longer cumulated.
If the flow exceeds the flow saturation, the flow measurement stagnates at 2.4 x nominal flow and
the volume is cumulated.
The „cut off“- function can also be used in case of hydraulic influences within the heating system,
e.g. in case of system vibrations. Thus it is possible to limit a possible faulty measurement.
When combining the integrator Supercal 531 with the static flow sensor Superstatic 440 the
threshold values „cut off“ and „flow saturation“ are programmed in the integrator Supercal 531 ex
works.
