1. Working principle of ultrasonic flowmeter

The working principle of ultrasonic flowmeter is as follows: When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a small change in the propagation time, and the change in propagation time is proportional to the flow velocity of the liquid. When there is zero flow, the time required for two sensors to emit and receive sound waves is exactly the same (the only technology that can actually measure zero flow). When liquid flows, the sound wave transmission time in the upstream direction is greater than that in the downstream direction. The function of ultrasonic flowmeter

1. Ultrasonic flowmeter can determine whether the liquid in the pipeline is flowing full. By borrowing the working principle of ultrasonic flowmeter, it is easy to determine whether the liquid in the pipeline is flowing full. If it is not flowing full, it can further determine the liquid level height in the pipeline. If the liquid level height is higher than half of the pipeline section, the flow velocity of the medium can be tested, and the actual flow rate of the medium in the pipeline can be calculated. Secondly, ultrasonic flow meters can determine the temperature of the medium inside the pipeline. The speed of sound of the medium at different temperatures varies, and ultrasonic flow meters can measure the speed of sound. With the known medium, the corresponding temperature of the medium can be measured by the speed of sound value of the ultrasonic flow meter.

Thirdly, ultrasonic flow meters can determine the type of medium inside pipelines and the type and type of medium inside sealed containers. This is in high demand in chemical enterprises, such as

when some media are flammable or explosive, or when different types of chemical substances are mixed and cause chain reactions, there is a risk of accidents caused by wind stroke blocking.

. So it is necessary to confirm the type of medium inside the sealed container again before adding materials. Some ultrasonic flow meters already have built-in physical properties of various chemical media such as NaClO/HCL, NaOH/HCL, NaClO/HNO3, H2SO4 (Suifuric acid) 93-100%, etc. As long as the sensor of the ultrasonic flow meter is attached to the outer wall of a sealed container, the type of medium inside the container can be tested.

2. Do you produce electromagnetic flow meters for non full tube liquids?

Its difficult to measure even if its not well managed. Ultrasonic waves can do this by adding a water level detection device. Based on the flow velocity and cross-sectional area, the flow rate can be calculated.

4. How to measure the sewage flow meter for the discharge outlet without a pipe

The sewage flow meter for the discharge outlet without a pipe can be measured by flow velocity measurement method, and the commonly used equipment is Doppler ultrasonic flow meter. Its measurement principle, applicable scenarios, and specific operating points are as follows: Measurement principle Flow velocity measurement method: Calculate the flow rate by measuring the flow velocity of sewage in the pipeline.

. Taking the Doppler ultrasonic flowmeter as an example, its probe emits a beam of ultrasonic waves obliquely upwards. When the ultrasonic waves propagate in the fluid, they will interact with impurities such as bubbles or particles in the fluid. Due to the c
