Product Description
The ultrasonic water meter is a type of water meter that measures water flow using the principle of ultrasonic wave propagation. Unlike mechanical water meters, it has no rotating impellers or pistons; instead, it calculates the flow rate by measuring the transit time or frequency difference of ultrasonic waves in the water flow.
Product application
No Mechanical Moving Parts
The water meter has an extremely low starting flow rate and high sensitivity, capable of detecting even small leaks.
No wear, long-term stability, and a long service life.
Wide Measurement Range
Wide range ratio: Bulk ultrasonic water meters can accurately measure both high and low flow rates, suitable for applications with large flow variations.
High Accuracy
Maintains high measurement accuracy across the entire range, ensuring precise metering.
Bidirectional Measurement
The ultrasonic water meter can easily measure flow in both directions, making it suitable for networks where reverse flow may occur.
Rich Data and Remote Transmission
With external communication modules (such as M-Bus, LoRaWAN, RS-485, 2G, 4G, etc.), it can output instantaneous flow, cumulative flow, pressure, temperature, and other data, enabling easy remote reading and network monitoring.
Easy Maintenance
Virtually maintenance-free, as the meter has no components like impellers or bearings that require regular cleaning or replacement.
