Optical Eye - Kamstrup flowIQ 3100 Series Technical Description

flowIQ® 3100

16.12 Optical eye

The meter is fitted with an optical eye that gives access to the meter's external interface, with which all the meter's
data registers can be read. For instance data can be read using Kamstrup's optical reading head. The reading head
includes a permanent magnet which switches on the optical eye. The interface communicates at 1200 baud.
In order to limit current consumption the default setting of the optical eye is OFF.
By means of a magnet sensor the optical eye will automatically switch ON, if an optical reading unit with magnet is
placed on the meter. The start-up time of the optical eye (from the magnet is attached to the meter until the optical
eye switches on) depends on the meter's mode as shown in the table below.
Note! Water meters are no longer polut neutral when detecting the optical eye; that means the optical eye
magnet must be orientated right, otherwise the optical interface will not be activated.
This applies to the following versions:
- wMBus from SW revision V1
- Sigfox
For Kamstrup's optical reading head a holder is available, which fits flowIQ® 3100 and is clicked onto the meter.
Below is a picture of optical reading head and holder.
