The statement regarding the hot-wire type air flow meter mentions that it has a simple construction and an optical sensor.

Analysis

1. Construction: Hot-wire anemometers are indeed known for their simple construction. They typically consist of a thin wire that is heated and placed in the air stream. The rate of cooling of the wire is proportional to the flow velocity, making the device relatively straightforward in design.

2. Sensor Type: However, a hot-wire anemometer does not use an optical sensor. Instead, it measures the temperature difference and electrical resistance to calculate airflow. Optical sensors are utilized in other types of flow meters, such as laser Doppler anemometers.

Final Summary

Given that the statement incorrectly asserts the presence of an optical sensor in a hot-wire anemometer, the statement is False.
