Frequently Asked Questions (FAQ)
What is a smart ultrasonic water meter?
A smart ultrasonic water meter measures water flow using ultrasonic signals rather than mechanical moving parts. When equipped with a suitable communication interface, it can transmit measurement data to compatible collection devices or remote management systems. The WM9100 series combines ultrasonic measurement with options for wired or wireless data communication, depending on the selected model.
How does the WM9100 ultrasonic water meter work?
The meter measures the difference in travel time between ultrasonic signals traveling with and against the water flow. This time difference is used to calculate water velocity and flow volume. Because the measuring principle does not rely on a rotating mechanical impeller, the meter avoids mechanical wear associated with moving measuring components.
What is the battery life of the WM9100 series?
The WM9100 series has a specified battery service life of up to 10 years under applicable operating conditions. Actual battery life may vary depending on the model, communication method, transmission frequency, and operating environment.
Can the WM9100 water meter support remote meter reading?
Yes. Selected WM9100 configurations support communication interfaces such as RS485 Modbus, M-Bus, LoRaWAN, and NB-IoT. Pulse output is also available on applicable models. The appropriate option depends on the existing network, data collection equipment, and remote management platform.
What is the difference between the WM9100-ED and WM9100-EV?
The WM9100-ED is a digital ultrasonic water meter designed for water consumption measurement. The WM9100-EV is a prepaid configuration with an integrated valve-control option. The choice depends on whether the application requires conventional metering or prepaid water supply management.
Does the WM9100 series support bidirectional flow measurement?
Yes. The series supports forward and reverse flow measurement. This feature is useful in applications where flow direction may change and where monitoring reverse flow is important.
