Product Description

                                   Small DN20 Ultrasonic Water Flow Meter

 

The ultrasonic water meter is a water meter based on ultrasonic measurement technology,No moving parts design to reduce wear.

Features

• Display with error and alarm codes including leakage detection.
• Ultrasonic water meter detection data is more accurate.
• Bi-directional flow measurements, Improved measurement accuracy, and applicability.
• Ultrasonic water meter is designed with no moving parts to reduce wear and tear.
• The water consumption value can still be accurately obtained at a low flow rate of 3L/h.
• Record total volume as small as 1mL.
