PRODUCT INTRODUCTION

Portable ultrasonic flow meter is suitable for on-line calibration and inspection measurement of liquid flow in various industrial sites. It has the characteristics of simple operation, high measurement accuracy, good consistency, on-line printing, long battery power supply and so on.
The ultrasonic wave carries information about the flow rate as it travels through a flowing fluid. Therefore, the flow rate of the fluid can be detected by receiving the ultrasonic wave, which is converted into flow. According to the detection methods, it can be divided into different types of ultrasonic flow meters, such as propagation velocity difference method, Doppler method, beam shift method, noise method and correlation method. Ultrasonic flow meter is a kind of flow meter which has been applied in recent years with the rapid development of integrated circuit technology
Non-contact instrument, suitable for measuring fluid and large pipe flow that is not easily accessible and observed. It can be linked with the water level meter to measure the flow of open water. The use of ultrasonic flow ratio does not need to install measuring elements in the fluid, so it will not change the flow state of the fluid, no additional resistance, the installation and maintenance of the instrument can not affect the operation of the production pipeline, so it is an ideal energy-saving flow meter.

WORKING PRINCIPLE

Ultrasonic flow meter is a device to measure the information of fluid velocity by detecting the effect of fluid flow on ultrasonic beam. According to the detection methods of signals, it can be divided into propagation velocity difference method, Doppler method, beam offset method, noise method and correlation method. Doppler method is to determine fluid flow by measuring ultrasonic Doppler frequency shift of scatterer in uneven fluid using acoustic Doppler principle. It is suitable for fluid flow measurement with suspended particles and bubbles. The beam migration method reflects the flow velocity by using the ultrasonic beam's propagation direction in the fluid as the flow velocity changes. At low flow velocity, the sensitivity is very low and the applicability is not great. At present is the most widely used is the "time difference method" measurement principle. Multi-pulse technology, digital information processing technology and signal processing circuit are combined to display the measured data in real time.
"Time difference method" is by sending the sensor to generate ultrasonic signal and send it out in the air flow, signal through the tube wall, fluid to the receiving sensor, at the same time, the receiving sensor diverges the same ultrasonic signal, signal through the tube wall, fluid to send the sensor. At this time, because the existence of the flow rate makes the time difference, the flow rate can be calculated according to the time difference, and then the flow rate.
