Product Details
Multi jet water with pulse output for bulk volume measurement in
cold water DN25 Brass
The multi-jet impeller water meter is with pulse output, for
control, metering or remote display of cold water flow rate.
Feature:
- Especially low head loss and extended measuring range
- Records small amount of water consumption
- Withstands high load for short time periods
- Maximum long term accuracy
- Forward and backward metering
- Strainer insert in inlet connection for cleaning without damaging
the seal
- Measuring data better than specified by calibration regulations
- Easily replacable pulse contact
- Pulse contact with screw connection or cable
Note:
- Measuring accuracy conform to ISO 4064 class B standard..
- Available with different length on request. Available in hot water
meter on request.
Working condition:
- Water temperature:0.1℃~50℃
- Water pressure: ≤1.6Mpa
Maximum Permissible Error:
(1) Between qt (included) and qs is ±2%;
(2) Between qmin and qt (excluded) is ±5%.
