一、Product Summary

Dear users, thank you for using our card ultrasonic flowmeter. Please read this instruction manual carefully before using it, so that you can easily use our products.

Card-type ultrasonic flowmeter is developed and produced according to China's national water meter standards GBT/778. 1-2018, JJG 162-2019, international water meter standards ISO4064-1: 2005, IDT and other standards.

The water meter adopts the unique ultrasonic propagation phase and time difference measurement technology newly developed by the company, and has the remarkable characteristics of high precision, low power consumption, wide measuring range ratio, stability and reliability, etc.

In the structure, the IP68 scheme of components is adopted, i.e. each component reaches the IP68 protection level, and the instrument cavity can ensure long-term operation even if water enters.

This series of water meters solves the problems of idling of traditional water meters, non-metering of small flow, excessive pressure loss and so on. It can be widely used in urban water supply pipelines, household water consumption meters, water intake monitoring of water resources, farmland irrigation, and also suitable for various industrial sites.

 

二、Working Principle

 

When ultrasonic waves propagate in flowing fluid, they carry the information of fluid flow rate, and the flow rate of fluid can be detected by the received ultrasonic waves, which can be converted into flow rate. Ultrasonic pulses pass through the pipeline from one sensor to another to achieve the purpose of measurement.

M03

Calendar, the first line shows the date and week; The second line shows the hours and minutes

M04

The first line shows the signal strength and fault error code; The second line shows voltage, temperature

M05

The water meter is equipped with 5 types of menu options, namely: main menu, auxiliary menu 1, auxiliary menu 2, quantitative control menu and time-sharing accumulation menu. Under the main menu, use the Modify key "" to enter any menu.

 

四、Performance characteristics

 

1. The pipeline is designed for fluid layered two-channel measurement, and the measurement is accurate

2. The range ratio is wide and lower than the initial flow rate of 0.01 m/s

3. large amount of information is display, 9-digit cumulative flow and 4-digit instantaneous flow are displayed on that same screen

4. The design concept is energy saving. For example, the instrument will start the automatic power saving function under the empty pipe or long-term fluid static state

5. Full IP68 protection grade design, all parts are completely sealed and protected, and can work normally for a long time even if water enters

6. It is designed to have cumulative recording function on time year, month and day, which can be viewed by pressing the key

7. It has a variety of communication interface modes: standard RS485 interface; M-BUS interface; Infrared communication interface; Support CJ-188 communication protocol.

8. Support standard MODBUS, M-BUS and HART communication protocols.

9 There are various ways to output signals: two isolated pulse signals can be used for output (where pulse equivalent and pulse width are programmable)

10. It has software online upgrade function

11. It has two-way PT1000 temperature measurement function, which can realize heat measurement

12. Built-in quantitative controller, which can automatically start the controller manually or at a set time, thereby realizing automatic timing quantitative water supply or quantitative irrigation

13. There are many options for the system of units, including cubic meters, American gallons, cubic feet and liters, depending on customer needs

14. Built-in lithium battery with battery life of more than 10 years
