A pitot head is a device that is typically used in aviation to measure airspeed. However, there are several synonyms for pitot head that are commonly used in specific industries. For example, in the field of fluid mechanics and engineering, the device is often referred to as a pitot tube or a pitot-static tube. These terms are used because the device is essentially a tube that is designed to measure fluid flow. In addition, the term stagnation probe is also used to describe a pitot head. This term is used because the device measures the stagnation point of the fluid flow, which is where the fluid velocity is zero.
