Product Details
Brass multi jet water meter for cold water volumetric measurement
DN25 Dry dial
The residential use, multi jet water meter and heat meters are made
of brass. Our multi-jet turbine meters are designed for situations
where a wide flow range must be covered. Quick responsiveness, even
at low flow rates, combined with power reserves for high flow
rates. All moval parts have an optimised specified weight.
Constructional details, such as the design of the turbines result
in excellent true running characteristics and minimum bearing
loads.
Combined with the special arrangement of the bearings and the
turbine, this guarantees a minimal moment of friction and a long
service life.
Feature:
- The hardened class
- High accuracy and large measure range
- Negligible head loss at work flow rate
- Magnetic drive, resistance to mangetic field interference
- High quality material with long service life
- Reliable in data collecting, hermetically sealed register
- The register is fully sealed, and could be in any position within
360°, conveniently installation
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%.
