How it works
Ultrasonic transit-time measurement. The page states the meter measures by the transit time method and carries a LoRa module for long-range automatic meter reading; no transducer configuration, path count, or electronics detail is given.
Features
- LoRa long-range transmission
An on-board LoRa module allows readings to be transmitted over long range.
- In-built data logger
Stores history records on the meter for later review.
- Transit-time ultrasonic technology
Stated by the source as providing accuracy and ultra-reliable metering (no accuracy figure given).
- Multi communication support
Source states multiple communication options are supported but does not list them.
- Dedicated daily information details
Daily consumption information is available on the meter.
- Five alarm indications
Five different alarm indications are provided; the source does not say what the five alarms are.
-
Compact size, easy to install
-
Long battery life
No battery chemistry, capacity, or service life in years is stated.
- Full-information LCD display
Displays consumption data and alarm states.

These labels appear in the datasheet, but the value beside them could not be read reliably from the document. Rather than print a figure we cannot stand behind, we have left them out — ask us and we will confirm them directly.
- Flow Range in m3/H - Max. Flow — the table has 5 pipe-size columns (15, 20, 25, 32, 40) but only 4 Max. Flow cells survived the text layer (3.125, 7.875, 12.5, 20). One cell is lost and the column mapping is unrecoverable, so the Max. Flow row is not published.
Applications
- • Industrial R.O. (reverse osmosis) plants
- • Residential water metering
- • Water supply schemes
- • Smart water billing
Frequently asked questions
How does the Ultrasonic AMR Meter measure flow?
It measures by the ultrasonic transit-time method, and shows the readings on a full-information LCD display.
How are readings collected remotely?
The meter uses AMR (automatic meter reading) over an in-built LoRa module for long-range transmission, and the page states that multiple communication options are supported.
Does the meter keep a history of readings if communication is lost?
Yes. The meter has an in-built data logger that retains history records, and dedicated daily information details are available on the meter.
