NB large caliber remote water meter

Introduction:

NB large-diameter remote water meter is an energy metering and control product developed based on large-diameter spiral wing water meter and NB-IOT IoT technology. adoptThe cellular narrowband IoT base station uploads water usage information to the wireless remote water meter on the water platform. Its signal network has deep coverage (underground surface wellsPipeline wells can be used, suitable for industrial metering, community pipelines, water companies and other places with high flow rates.

Technical parameters of NB large-diameter remote water meter:

(1) The pipeline is designed for fluid stratified dual channel measurement, ensuring accurate measurement.

(2) The range ratio R (Q3/Q1) is 160.

(3) Display a large amount of information, displaying 8-digit cumulative flow and 4-digit instantaneous flow on the same screen.

(4) The design concept is energy-saving, such as the automatic power-saving function of the instrument when the air pipe or long-term fluid is stationary.

(5) The design has cumulative recording and data collection functions in years, months, and days.

(6) It has multiple communication interface modes: optoelectronic interface, RS-485 interface, M-bus interface.

(7) Supports standard Modbus and CJ-188 communication protocols.

(8) By using ultrasonic flow measurement technology, multi angle installation can be achieved without affecting instrument measurement.

(9) Built in energy type lithium-ion battery with a battery life of over 6 years.

Advantages of NB large-diameter remote water meter function:

(2.1) High protection level: Advanced copper sealing technology is adopted, with an overall protection level of IP68, ensuring that it will not be affected by moisture and surface fogging;

(2.2) Accurate Reading: Using infrared photoelectric transmission sampling, it is not affected by ambient light, has no mechanical contact or action, and is not affected by vibration caused by pipelines or other factors, resulting in reading errors. The real-time reading value is completely consistent with the mechanical indication;

(2.3) Long service life: It adopts low-power design and is only powered by the collection device for a short time during reading. The electronic unit has a short working time and a service life much longer than the national mandatory water meter inspection cycle;

(2.4) Safety of use:<The strong electrical power supply is physically isolated from the water meter, with high insulation strength to ensure safe use>;

(2.5) Real time reading function: It can read out the measurement data and status data in the meter in real time according to remote instructions. Real time collection of current water readings to provide measurement assurance for accurate calculation of production and sales differences;

(2.6) Measurement accuracy: The sensor is non-magnetic and non-contact, and there is no external magnetic interference causing inaccurate readings. The electronic reading device does not affect the measurement accuracy of the original instrument;

(2.7) Remote transmission function:<Using M-BUS or RS485 interface to achieve data remote transmission and centralized monitoring of water meters without power supply. During reading, the collection device provides short-term power supply, and the electronic working time is short. The effective working life of the whole machine is much longer than the strong inspection time>;

(2.8) Easy maintenance: The electromechanical conversion module adopts a plug-in design, which can be independently installed with the water meter. This module has strong universality and comprehensive interchangeability, and can be transplanted between two types of water meters;

(2.9) Strong compatibility:<Supports multiple standard communication interface outputs, can easily and quickly access various management and scheduling systems>.
