ultrasonic water meter smart digital

Ultrasonic water meter is to detect ultrasonic waves in the water downstream and counter current propagation time difference, This new all-electronic water meter is calculated by the program analysis and processing of water flow rate and then calculate the water flow.
Brand name:
  • LXC-DN15~DN40

ultrasonic water meter smart digital


Small cablier-DN15~40



System structure diagram as follows
· Server send commands to the data concentrator through network;
· Concentrator transforms the received commands into radio signal and send the signal to the water meters;
· Water meters respond and execute the commands accordingly;
· Water meters deliver the result or data back to the management center as per the original route after the actions finished.

· Quality Gurantee: Water meter for 1 year;
· Support install guide & test in site;
· Date sheet can be sent to other management system easily.


Brief introduction

Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic beam propagates in the opposite direction of the water, and analyzes and processes the flow rate of water to further calculate the flow of water.


·Features long service time and high accuracy
·Threaded connection digital water meter, used in industrial pipelines, suitable for high pressure environment, can choose whether to install pulse output
·With remote transmission system software to support reading and monitoring
·Provide a complete software metering and charging solution
·Automatic leak measurement


·Applicable scene:home、apartment、garden housing 、ground、commercial、residential building、malls、household portable、garden、domestic residential
·Technical data conform to international standard ISO 4064.
·Communication:rs485 modbus、LoRa
·Fitting:Pressure sensor、battery、lcd display、reading device、data logger、liquid turbine、user interface unit、reading device、actuator、connection fittings、Valve


·No mechanical movable parts,Impurities in water can’t be affected, long service life.
·Wide measurement range. Very small flow can be measured.
·Various alarm functions:Battery voltage can alarm、empty tubes or pipes that are not full of water、transducer fault alarm and more.
·Low-power design and the use of high-energy batteries, can work for 8 years and more.
·The communication interface is Lora or Rs485, can achieve remote real-time monitoring and management on the LAN.

Water meter

1. How long is the battery life?

Using the ER26500 battery with a capacity of up to 9000 mAh and the frequency of reading the meter once a day, the battery life can reach 8 years.

2. Waterproof rating?

At present, this water meter adopts completely encapsulated and sealed technology. It uses silicone to package the circuit board part, and the battery plug and socket are also sealed to achieve IP68 protection.

3. Can your product run underwater?

This product can be soaked in water, but soaking in water will affect the stability of signal transmission, because it will greatly affect the signal transmission in water

4. If the valve cannot be closed or opened, how to find and deal with it?

If the valve is blocked by sand and gravel flowing into the pipe, the program in the water meter will try to execute the on-off valve action within 40 seconds.

If the valve cannot be switched normally, the water meter will give up the command and return the fault data to the platform.

On the platform, you can easily view the relevant information of the water meter.

Pre-sales and after-sales service

1. Pre-sale service

Patient product introduction.

AMR system demonstration.

Project case introduction.

Support sample ordering.

2. After-sales service

Installation instructions, including software part and water meter part;

Support data to the third management system;

Installation supervision, on-site debugging and advertising training;

Maintain long-term tracking and service, even beyond the warranty time

Communication and service platform

1. What data can the platform collect from the water meter?

Currently, our platform can collect cumulative flow, battery voltage, and upload time on the water meter.

2. How do you know that the water meter is faulty and there is no data to return?

First, we can check the alarm function on the platform to see if the water meter has no data returned, and then check the installation environment to see if there is any obvious damage, and can actively trigger the water meter to turn on-line mode 

3. Is the platform free? Can I pay in advance?

It is free, and the administrator can charge the amount in advance

Set user information files for each user on the platform

4. Warranty?

Within one (1) year from the date of acceptance, it will be guaranteed that the working principles and materials of all meters are free from defects. Any defective instruments or parts found during this period should be replaced free of charge when returned to SHMETERS.
