Ultrasonic water meter for utility volumetric flow measurement billing DN25 brass housing
Our ultrasonic water meter is designed for volumetric flow measurement in residential, houses, buildings and commercial water supply sub stations for water supply, flow measurement, and settlement of charges payable by water consumer based on meter measured.
Product features
● Size specification: DN15, DN20 and DN25;
● Dynamic range: R400;
● Starting flow rate as low as 0.002 m3/h;
● Provides sustained accuracy within ±2%;
● Mounting in any installation position in difficult circumstances;
● Integrated mechanical design with protection class of IP68;
● No moving parts eliminate mechanical wear and pressure loss;
● Lithium battery with lifetime over 10 years (measuring cycle: 1s);
● Optional with wired lead or AMR/AMI devices;
● Communication interface: Optical, M-BUS/RS-485, RF.
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%
