Residential Ultrasonic Water Meter with Modbus System
Application
The meter is suitable for use in living houses, buildings and at district water supply sub-stations for supply water flow measurement and settlement of charges payable by water consumer based on meter-measured.
Product Details:
Micro power consumption/low starting Flowrate/high stability, specially designed for living houses, buildings and at district water supply sub-stations for supply water flow measurement, satisfies the demands of settlement of charges and accurate measurement of water utilities.
1.Remote valve control, prepaid function and wireless networks
2. Applied micro power consumption, battery powered (one battery for continuously work over 10 years)
3. Low starting rate (1.5L/h), able to accurate measure Flowrate as low as 0.006m3/h
4.Dynamic range (Q3/Q1) achieved 250:1 (better than Class D)
5. No mechanical moving parts, no abrades and has a long serving lifetime
6. IP68 protection, able to work under long-term submersion in water
7. Small size, high stability and anti-interference ability
8. Utilize ultrasonic measuring technology, able to mount in multiple angles whilst reduce the pressure loss to a minimum
9. Support photoelectric, RS-485 and M-BUS output interfaces and provides Radio Frequency and remote meter data reading functions for concentrated management. Actively report alarms of pipeline network.
