How it works
Ultrasonic transit-time measurement with LoRa-based automatic meter reading. The source gives no description whatsoever of the flow control valve: its type, actuation, control logic, and relationship to the metering element are all unstated.
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 is stated.
- Full-information LCD display
Displays consumption data and alarm states.

1 further specification is listed in the datasheet but not reproduced here
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.
- Max. Flow (m3/h) per pipe size — the text layer holds only four values (3.125, 7.875, 12.5, 20) for five pipe-size columns (15/20/25/32/40), so no value can be mapped to a size with certainty
Applications
- • Industrial R.O. (reverse osmosis) plants
- • Residential water metering
- • Water supply schemes
- • Smart water billing
Frequently asked questions
How does this meter measure flow?
It measures by the ultrasonic transit-time method and shows readings on a full-information LCD display.
How are readings collected remotely?
Through AMR (automatic meter reading) over an in-built LoRa module for long-range transmission; the page also states that multiple communication options are supported.
