Overview
UF2800 series reflective ultrasonic water meter is based on the principle of ultrasonic "time difference method", which can measure the flow rate of water in the pipe and then obtain the flow measurement method. The flow meter parts and integrator are completely independent research and development. The production of the product has a strict production process, perfect detection means, in line with the national standard GBT778-2007;
Application
Ultrasonic water meters are used to measure and display the volume flow or mass of water flowing through the pipeline:
Main application areas: municipal water supply company residential building water supply network system household table of all kinds
Water supply network system for commercial buildings;
Measurement of main water pipeline of residential buildings;
Water metering system of various commercial, school and other construction companies;
Product features
■No moving parts, never wear, measurement accuracy is not affected by the use cycle;
■Not affected by magnetic materials, impurities and chemicals in the medium;
■Horizontal vertical arbitrary installation;
■High measurement accuracy, ultra-low power consumption, stable and reliable work;
■Using TI micropower MCU design, life can reach more than 8 years;
■A variety of communication methods can be selected with photoelectric interface, pulse, RS485With self-diagnosis function;
■With self-diagnosis function;
