An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow or by measuring the frequency shift from the Doppler effect.

Beside the basic function, HWT ultrasonic flow meters has the ability to record water temperature, positive or negative water flow, significant and unwanted change in water consumption, potential hazard, early warning in various problematic situation (low battery, probe defect, water leaking, unauthorized access, freezing, etc).
Considering the needs of today consumers, HWT introduces several sub-models to this group of products…
