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.
- 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 therefore unrecoverable, so the Max. Flow row is not published.
Applications
- Residential water metering
- Industrial RO water metering
- Water supply schemes
- Smart water billing
Frequently asked questions
How does the Accumax ultrasonic water meter measure flow?
Measurement is based on the transit time ultrasonic method.
Can it be used for both residential and industrial metering?
Yes. It can be used for industrial applications as well as residential applications, including industrial RO, water supply schemes and smart water billing.
Does the meter store historical readings?
Yes. It has an in-built data logger for viewing history records, plus dedicated daily information details.
What alarms does it provide?
The page states five different alarm indications are provided, viewable on the LCD display, but does not say which conditions they cover.
