Smart ultrasonic water meter is developed based on the principle of ultrasonic transit-time measurement technology. In other words, by using a state-of-the-art signal processing to determine the travel time difference between the ultrasonic waves, which results in highly accurate velocity measurement. The instrument integrates measurement, calculation and display. It uses micro-power technology. A battery can be used for more than eight years and we use ER26500 default,if you have special requirement we can change it to ER34615. It can measure the minimum flow rate of 0.01 m³/h very accurately and according to the international standard OIML R49/MID. At the same time, the instrument has the characteristics of small size, high stability and strong anti-interference ability
Ultrasound flow measurement technology is used to achieve multi-angle installation that doesn’t affect the meter accuracy, nor the system pressure loss
Mainly used for household measurement of residential quarters
with Lora communication mode can be connected to a concentrator. the Wireless data collector produced by our company use GSM mobile or Ethernet network for data transmission to form a wireless monitoring system
When the pipeline network runs abnormally, it can actively report the abnormal information of all the devices connected to the network

Ultrasonic pipeline:The meter’s body (pipe) structure has no mechanical moving parts and no wear/tear. Which makes it maintenance free. It is resistant to any disturbance of ripple flow, which make the measurement highly accurate. The structure of the pipe is simply built to overcome the high pressure loss and eliminates any leakage
Transducer:Adopting High-performance piezoelectric devices, makes the metervery stable and highly accurate. The reflector material is stainless steel which prevents all sediments wear resistance, impact resistance, aging resistance, high temperature resistance, corrosion resistance... etc
Receive signals from flow sensors and temperature sensors for flow calculation, storage, display systems, data transmission, etc
User can use magnetic rods to switch between display screens, view the relevant data measured by the instrument. The meter displaysthe data in a round robin menu structure.
Among the parameters displayed: Instantaneous flow (m³/h), cumulative flow (m
³ ), screen detection, table address, cumulative working time (h), date (year/month/day), caliber, software version…etc. As shown in the picture below

The whole system mainly consists of ultrasonic water meter with Lora (MBUS, RS485)communication, collector &repeater and management system
1. Installation and Connection Requirements:
Installation should be strictly in accordance to the site professional engineering design, and alteration without engineers permission should be strictly prohibited
2. Instrument Installation Position:
Installed in vertical pipeline for upward (or oblique upward) flow of liquid, followed by horizontal pipeline, try to avoid downward flow of liquid. (or oblique downward) flowing pipes to prevent liquid from running with the gravity and create air pockets
Installation position should not be selected at the highest point of pipeline direction to prevent abnormal measurement due to bubble accumulation in pipeline
3. Installation method
Cut off the installation instrument of the water supply pipeline and set aside the
location of the installation instrument as shown in the figure
Concentric alignment of instrument,
Pipeline and tightening of pipeline blade and instrument thread with the appropriate wrench
Instrument installation completed
a )The water meter shown as :
It means that the battery is not enough, and the battery should be replaced assoon as possible
b) The water meter is reading negative:
Check whether the flow direction is reversed. If not, please contact usimmediately
c) Abnormal or random beating of cold-water meter data:
Installation position is incorrect and installed at lower water level
The front and rear straight section is too short, the bend is too big, and thediameter of the pipe before the table is large.
d) Water meter has flow and no temperature:
Please do not dismantle it manually and contact us immediately
Transportation and storage
1. The water meter should be stored in the original package, the ambient
temperature is 5-40℃, and the air is free of corrosive gases
2. when the water meter is stored on the shelf, the stacking height of the boxes
should not be more than 5 boxes
1. This water meter is used in residential, commercial and light industry (E1 level) and
installed indoors in a fixed water meter (B level)
2.MWmeter instructions do not contain any explicit or implicit warranties. MWmeter has
the right to modify and revise the instructions. If there are any changes without
notice, all the actual products will be the main products
