Handheld ultrasonic flowmeter

Recently, many netizens are asking what is the meaning of handheld ultrasonic flowmeter, and what is the difference with ordinary ultrasonic flowmeter? Before answering this question, let's briefly introduce ultrasonic flowmeter! 　　Ultrasonic flowmeter adopts the 'time difference method' The measuring principle is to generate an ultrasonic signal by sending a sensor and disperse it in the air stream. The signal passes through the pipe wall and the fluid to the receiving sensor. At the same time, the receiving sensor emits the same ultrasonic signal. The signal passes through the pipe wall and the fluid reaches the sensor. Send on the sensor. At this time, because of the time difference due to the flow velocity, the flow velocity can be calculated based on the time difference, and then the flow rate can be calculated. The structure of ultrasonic flowmeter is mainly divided into ultrasonic signal generator, signal receiver, information processing circuit, and flow display. Among them, the ultrasonic signal generator first sends a signal, receives the sensor to receive the signal, obtains the time difference, and processes the ultrasonic information according to the information processing circuit, transmits the flow to the display screen in the form of an electrical signal and displays the result.　　 Ultrasonic flow meters can basically be divided into plug-in ultrasonic flow meters, pipe section ultrasonic flow meters, clamp-on ultrasonic flow meters and portable ultrasonic flow meters.　　Plug-in ultrasonic flowmeter: can be installed and maintained without stopping production. Using ceramic sensors, use our company's special drilling device for non-stop production installation. Generally, it is a single channel measurement. In order to improve the measurement accuracy, three channels can be selected.　　Pipe-segment ultrasonic flowmeter: It is necessary to cut the pipeline for installation, but the production can not be stopped for future maintenance. You can choose a single-channel or three-channel sensor.　　 External ultrasonic flowmeter: It can complete fixed and mobile measurement. Use special coupling agent (silicone rubber cured at room temperature or high temperature long-chain polymer grease) to install, and the pipeline will not be damaged during installation.　　 Portable ultrasonic flowmeter: portable use, built-in rechargeable lithium battery, suitable for mobile measurement, equipped with a magnetic sensor.　　 Having said several kinds of ultrasonic flowmeters mentioned above, everyone will definitely have questions. Why is there no hand-held ultrasonic flowmeter? In fact, hand-held ultrasonic flowmeter is only one of the classification methods. The hand-held ultrasonic flowmeter also does not need to be installed by breaking the tank, and when there are multiple pipes to be measured, its advantages are highlighted. Since the measurement method is very convenient, it can be disassembled and installed to measure the flow rate of the next pipeline after completing a measurement and reading. This method can be said to be perfect for industrial occasions where real-time monitoring is not required and the workload is heavy. In fact, the editor does not have a deep understanding of the relevant knowledge of handheld ultrasonic flowmeters. I believe that everyone still has a lot of questions. The editor here recommends a place for everyone-Kaidi Sensing Technology Co., Ltd. is a professional production automation company. The instrument manufacturer knows no more about ultrasonic flowmeters.
