7.11 Calibration
The metering pump is calibrated at the site to the flow rate of the
corresponding pump type at nominal pressure.
The corresponding flow rate and the nominal pressure is given in the
technical data in the operating manual.
The specified metering capacities in metering pumps are always
determined under ideal conditions (metering of water at
20 °C, short
suction and metering pipes, rated back-pressure, no pressure-
boosting valves in the metering line).
We suggest performing another calibration on the pump again after
installation and thus to adjust it to the on-site operating and ambient
conditions. This corrects any deviations in the performance data (e.g.
due to cable cross-sections, back-pressure, temperature).
