supply failure
In the event of a power failure, the flow meter data are backed up on a non-volatile inter-
nal memory. In case of devices with display, the characteristic sensor values, such as no-
minal diameter, serial number, calibration constants, zero point, etc. and the error history
are also stored on a microSD card.
