Products Description
Mid Approved Water Meter is an ultrasonic water meter for urban residential and industrial use, designed with cutting-edge technology. It integrates intelligent wireless communication and advanced data analysis capabilities, with excellent metering performance, which can effectively reduce non revenue water and improve water efficiency. This product has an innovative structure and provides a lifespan of up to 12 years, with performance far exceeding traditional mechanical water meters. Due to the absence of mechanical moving parts inside, it maintains stable measurement accuracy throughout its entire lifecycle and requires no maintenance at all. At the same time, by using high-quality engineering plastics and copper materials with high strength and pressure resistance, the wear resistance and durability of the product have been significantly improved.

Main Features
1. Wide dynamic range option: Provides R400 range selection to ensure accurate measurement at different flow rates.
2. U0/D0 compatible design: Accurate measurement can be achieved without extending the pipeline.
3. Micro flow detection capability: It can detect flow as low as 10L/h and accurately measure the minimum water consumption.
4. Anti impurity and magnetic field interference: not affected by water quality impurities or external magnetic fields, ensuring measurement accuracy.
5. Long service life: Reliable operation for over 12 years, significantly improving equipment reliability.
6. Assembly free installation adaptability: Supports direct installation of multi-directional pipeline configurations such as vertical/horizontal.
7. Pure water fluid measurement: eliminate air interference and focus on precise measurement of water flow rate.
8. IP68 protection level: fully resistant to dust and environmental factors, ensuring long-lasting and reliable operation.
