13.1

Encryption

flowIQ®

3100 can be ordered without or with encryption of data transmission. If encryption of data is

selected, it consists of 128 bit AES counter mode encryption.

Kamstrup

A/S recommends encryption.

)

Meters produced for Russia will always be WITHOUT encryption.

Communication (KMP)

The meter has an optical communication interface on the front. The interface communicates at 1200 baud

and can be used if an optical reading head is connected to METERTOOL and LogView.

14.1

Optical eye activation

In order to limit current consumption the optical eye is usually switched off. The meter's optical

communication is automatically switched on 4 sec. after having placed the magnetic optical reading head

on the meter.

METERTOOL for flowIQ® 3100/MULTICAL® 21/flowIQ®21XX

METERTOOL is a PC program,

giving access to change the customer selected parameters of a water meter

configuration and read its data memory without dismounting the meter from the installation.
