**Title: The Diverse Applications of Clamp-On and Insertion Ultrasonic Flow Meters**
In the realm of flow measurement, ultrasonic flow meters have emerged as a reliable and efficient solution. Among them, clamp-on and insertion time-difference ultrasonic flow meters have their own unique characteristics and find application in a variety of scenarios. Let's start with clamp-on ultrasonic flow meters. One of the key advantages is their non- invasive nature. In the HVAC (Heating, Ventilation, and Air Conditioning) industry, they are highly favored. For example, in commercial building HVAC systems, where the existing piping infrastructure needs to be monitored without causing any damage or disruption, clamp-on ultrasonic flow meters can be easily attached to the outside of the pipes. This allows facility managers to accurately measure the flow of chilled water or refrigerant, ensuring the optimal performance of the HVAC system and energy efficiency. Another significant application area is in water distribution networks. Municipal water supply companies often use thes
