Product Type  : Ultrasonic Water Meter PCB

Product Detail:

1. Product introduction
Ultrasonic water meter is consist of flow sensors, temperature sensor (with choice) and measuring electronics modules with the characteristics of impact construction and easy installation. Ultrasonic water meter are non mechanical movement, non wear and non effect from bad quality water, which can be maintained with low cost with horizontal or vertical installation.
Ultrasonic water meter electronic module that is the key part for the ultrasonic water meter measures the flow rate through the time difference from the inlet water and return water with measuring the ultrasonic. The module not only can measure the flow rate through the temperature sensor(with choice) but also can add the M-BUS or RS485 interface to realize the different needs for remote reading from different users, which is can be centralized management. The real photo for the ultrasonic water meter electronic module is as following:

   (2)Function Characteristics 
       1 high accurate measuring function:using picosecond high precision time chip, high accuracy and good stability
       2 Display Function: Use high-resolution LCD panel displays the total flow rate, instantaneous flow rate and total         working time and other information;
      3 Automatic data record:  recording the recent 24 months history data including the total flow rate , safe and reliable
      4 This module can return to the user mode automatically after 3hours in the calibration mode.
      5 with infrared communication interface, which enables parameter setting, flow calibration, centralized meter reading function;
      6 with M-BUS bus or RS485 data bus remote function, it can realize parameter setting, flow calibration, centralized meter reading function, in the meanwhile the data communication process maintains a very low current consumption, which can significantly extend battery life;
      7 The module can be used on many types of ultrasonic flow pipeline that can be applied to different diameter from DN15 to DN300, and better adaptability to the ultrasonic sensor, the sensors need not be paired;
      8 The electronic module is equipped with a dedicated calibration system that can achieve the parameters setting, system correction, error calculation, the derivation of original data records and other functions. At the same time, electronic modules and calibration systems are used with combination,which can make the whole process of flow testsimple, fast and efficient and can also complete three times per hour for three flow points testing or calibration.
      9 Fault diagnosis, record and display functions;battery and flow rate real-time monitoring;record the date and time of valid data failure;
      10 circuits using advanced SMT surface mount technology, every piece of circuit board in the factory have dynamic current, quiescent current, M-BUS communication current, liquid crystal display, the volume of the flow, M-BUS communication, RS485, infrared communicationstestingto ensure that the products meet the technical quality requirements.
