- R value is R80
- Suitable for both cold and warm water applications
- Replaceable meter inserts available
- Good readability even at extreme operational conditions
- Optionally retrofittable with pulse contactors
Working condition:
- Water temperature:0.1℃~40℃ for cold water
30℃~90℃ for hot water meter. - Water pressure: ≤1.0 Mpa
Note:
- Measuring accuracy conform to ISO 4064 class B standard..
- Available with different length on request. Available in hot water
meter on request.
Maximum Permissible Error:
(1) Between qt (included) and qs is ±2%;
(2) Between qmin and qt (excluded) is ±5%.
