Ultrasonic flowmeters use ultrasonic waves to measure flow rate of fluids. The calculation is done from frequency shift of a transmitted ultrasonic signal that has travelled through the process fluid. The working principle of ultrasonic flowmeters is based on Doppler effect or Transit-time type. Although both these technologies are based on ultrasonic signals, there are major differences in the way the signal is transmitted and received. This difference makes them ideal for a wide range of fluids such as liquids, gases, and steam.

Milling is a method of removing excessive or unwanted material from any metal or other objects using rotary cutter. It helps to give the workpiece desired shapes and sizes. The process is performed using milling machines that are either manually controlled or automated or both. In the automatic or semi-automatic type, the operator of the machine programs the machine to perform milling operations automatically. A CNC (computer numerical control) milling machine is a variant of milling machine. The CNC milling machine offers a wide range of procedures that can be used in a variety of end-users industries. Automotive, aerospace, electrical and electronics industries are the major end-users of CNC milling machines owing to the high requirement for precise equipment. Several players in end-user industries are shifting toward automation, which, in turn, has propelled the demand for CNC milling machines. These machines require less human intervention and enable endusers to increase production efficiency and eliminate errors. Therefore, several endusers have switched to autonomous machines and hence the demand for CNC milling machines has increased in recent years.

Chemical or bio-fogging has been prevalent in the market for decades and plays a crucial role in sanitation and disinfection.
