1. The flow sensors are type-approved for the dynamic ranges qp:qi = 250:1 and 100:1, but are as standard delivered as 100:1.
Please contact Kamstrup A/S for further information.
2. In some countries, bi-functional meters type 3 and 6 are only allowed to be assigned with the MID marking due to national law.
3. The battery lifetime is affected by the meter’s communication and setup parameters as well as transmission interval, transmission power and data-
gram contents.
Please contact Kamstrup A/S for calculations of specific configurations.
