1.working principle:
Handheld ultrasonic flow meters use the transit-time measurement principle to determine the flow of liquids. The device consists of a transducer that transmits ultrasonic waves through the liquid under test. The transducer also acts as a receiver, detecting ultrasonic waves passing through the liquid. Ultrasonic waves travel through a liquid at different speeds, depending on the flow rate of the liquid. As the fluid flows to the transducer, it is accelerated and takes less time through the fluid. Conversely, when fluid flows away from the transducer, it slows down and takes more time to pass through.
Ultrasonic flow meters measure the difference in transit time between downstream and upstream propagating waves. This time difference is related to the flow rate of the liquid and is used to calculate the flow rate using the algorithm and pipe size.
Easy to install, portable and easy to use, this handheld device is ideal for measuring liquid flow in the field without interrupting liquid flow or shutting down pipes.

2.Applications:
Handheld ultrasonic flow meters are used in a variety of industries including water treatment plants, chemical processing, petroleum, food and beverage production, HVAC systems, and many more. It is especially useful where the fluid being measured is corrosive, toxic or hazardous to handle.
In the water treatment industry, this meter is used to measure the flow of water in pipelines and other treatment processes. In the chemical processing industry, it is used to measure the flow of chemicals to ensure correct dosage and quality control. In the petroleum industry, it is used to measure the flow of petroleum and other pressurized fluids in pipelines and subsea systems.
HVAC engineers use this flow meter to measure the flow of heating and cooling fluids and adjust the system accordingly for optimal performance. In the food and beverage industry, it is used to measure the flow of products such as dairy, beer and beverages to ensure that no product is wasted and that the manufacturing process is running smoothly.
