Installation guide | Supercal 5
During commissioning the pipe system must be purged. Air in the system of
the flow sensor may affect the measurement.
Use only new and appropriate sealing material.
Water tightness of the different connections should be verified.
The Supercal 5 is a compact calculator and consists of the following two partial
units:
Measuring and calibrating-relevant upper part
Lower part
The pulse values of the calculator and of the flow unit, as well as the resistance
value of the temperature sensors (Pt500) must match. Compare the labels of the
devices!
