Note that in heat applications, the water tem-
perature must be greater than the ambient tem-
perature.
Once commissioned, avoid frost at the meter.
Use unsealed flow sensors:
• at water temperatures permanently above ambient
temperatures
Use sealed flow sensors:
• For cold applications or T
water
< T
ambient
• If permanent condensation is expected
7. Disposal
The meter (standard version) contains a lithium
battery, which is not rechargeable. Do not use
force to open the battery.
It must never come into contact with water,
short-circuited or exposed to temperatures over 75 °C.
Empty batteries and no longer required electronic devic-
es or components are hazardous waste.
This device must not be disposed together with the do-
mestic waste.
Return it to the manufacturer for recycling.
