Is the awm730p1 airflow sensor a hot wire type or a differential pressure type?

Hi everyone

I checked the Awm730p1 airflow sensor data sheet.However, Honeywell did not specify the type of sensor.
If anyone knows please tell me, thanks

GENERAL INFORMATION
AWM700 Series airflow sensors operate on the theory of heat
transfer due to mass gas flow across the surface of the
sensing element. The sensing element consists of a resistor
bridge heater circuit and dual temperature-sensing resistor
bridges. This configuration senses mass flow rates and flow
direction. "

says what it is.

The text description seems more like a hot wire type, and it may not use alloy docking wire, but a resistor-like material.
