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.
