Household-use Ultrasonic water meter
SCL-61H series DN15~DN25
Features
1. Large dynamic range R250, and (metrological properties) better than Class D
2. SLC-61H ultrasonic water meter is designed to work on propagation velocity difference principle. It is a meter working with measurement-integration-display integrated functions and micro-power consumption technology (The lifetime of the battery is over 10 years).
3. A flowrate as low as 0.006m³/h can be precisely measured. It enjoys the merits of being compact in size and high in stability and anti-interference capability.
4. Thanks to its use of ultrasonic measuring technology, the meter can be installed in different angles without being affected in measuring accuracy. Moreover, the pressure loss of pipe flow can be reduced to a minimum.
5. It is a meter specifically designed for use in households in a living quarter or sub-district.
6. Through coupling with our companys GSM wireless data acquisition unit, the meter can carry out wireless data transmission through GSM public network to form up a wireless monitoring system. Whenever pipe network runs abnormally, the abnormality information can be timely reported to upper level..
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.
