Ultrasonic flow meter knowledge introduction
Apr 04, 2018

What is a gas ultrasonic flowmeter? Ultrasonic flowmeter is suitable for high-pressure, large-caliber, high-accuracy I-day gas flowmeters and load cells, because of its high measurement accuracy, wide range ratio, low installation cost, and no Pressure loss, no moving parts, installation and usage fees are all welcomed by users.

 

Most of the ultrasonic flowmeters come in the form of a single unit consisting of a measuring tube and a wall-mounted transducer. So far, many national government agencies have approved ultrasonic flowmeters as legal measuring instruments.

 

According to the detection method, the small scale of the weighing sensor introduced, the ultrasonic flowmeter can be divided into different types of ultrasonic flowmeters such as the differential propagation velocity method, Doppler method, etc. The ultrasonic flowmeter is not easy to contact and observe the fluid and large diameter flow measuring. Now has a variety of measurement, there may be a difference frequency ultrasonic flowmeter according to the techniques of sub-products, plug-in ultrasonic flowmeter, the ultrasonic flowmeter time difference.

 

The basic principle of an ultrasonic flow meter is the information of the flow rate of the fluid carried by the ultrasonic wave as it travels in a flowing fluid. The official said that the flowmeter can be divided into two types, plug-in and clip-on, according to the ultrasonic installation method of the transducer. The output methods of the flowmeter include pulse output, analog books and digital communication output.
