Ultrasonic water meter, convectional type DN20 brass tube for
sanitation water utility Mbus communication
Our convectional water meter and heat meter, are ideal for
transient and totalization flow, no moving parts, it has no
pressure loss. These are ideally for water utility for water and
energy management, measurement and billing.

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℃～40℃( 0.1℃～90℃ for hot water meter)
- Water pressure: ≤1.0Mpa
Maximum Permissible Error:
(1) in the lower zone from qmin inclusive up to but excluding qt is
±5%
(2) in the upper zone from qt inclusive up to and including qs is
±2%
(3) Hot water meter ±3%
