Plug-in ultrasonic flowmeter: special drilling device can be installed without stopping production. Generally, it is a single channel measurement. In order to improve the measurement accuracy, three channels can be selected.

    Pipe-segment ultrasonic flowmeter: The pipeline needs to be cut for installation, but the production can not be stopped for future maintenance. Optional single-channel or three-channel sensor.

    Clamp-on ultrasonic flowmeter: It can complete fixed and mobile measurement. Use special coupling agent (room temperature curing silicone rubber 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 magnetic sensors.

    Handheld ultrasonic flowmeter: small size, light weight, built-in rechargeable lithium battery, handheld use, with magnetic sensor.

    Explosion-proof ultrasonic flowmeter: used for liquid flow measurement in explosive environments, explosion-proof and intrinsically safe. That is, the converter is explosion-proof, and the sensor is intrinsically safe.

    Flow measurement system: It is composed of multiple ultrasonic flowmeters and the main station of the system. Suitable for centralized measurement of multiple pipelines.

    Ultrasonic calorimeter: used for heat measurement of heating system.

    Battery-powered ultrasonic flowmeter: an integrated ultrasonic flowmeter powered by a lithium battery. It is suitable for occasions where there is no commercial power supply. A battery can be used for ten years and has a variety of measurement functions.

The tube segment ultrasonic flowmeter integrates the transducer and the measuring tube, which solves a problem in the measurement of the externally attached flowmeter. Moreover, the measurement accuracy is higher than other ultrasonic flowmeters, but at the same time, it also sacrifices the advantages of continuous flow installation of the external ultrasonic flowmeter, and requires cutting the pipe to install the transducer.

    Plug-in

    The plug-in ultrasonic flowmeter is in the middle of the above two. In the installation, it can flow continuously. Use special tools to punch holes in the pipe with water, insert the transducer into the pipe, and complete the installation. Since the transducer is in the pipeline, its signal transmission and reception only pass through the measured medium, not the pipe wall and lining, so its measurement is not limited by the pipe quality and the pipe lining material.

    Selection of ultrasonic flowmeter

    In addition to the above-mentioned types of ultrasonic flowmeters, digital ultrasonic flowmeters using digital circuits, integrated ultrasonic flowmeters combining transducers and converters have appeared in recent years, and so on. In the face of many types of ultrasonic flowmeters, users must choose a reasonable model according to the actual situation and measurement needs.

    Doppler Ultrasonic Flowmeter

    It can only be used to measure fluids that contain a proper amount of particles or bubbles that can reflect ultrasonic signals, such as factory effluent, untreated sewage, and factory process fluids with stable magazine content. It should be noted that it has strict requirements on the measured medium, that is, it cannot be clean water, and the acrobatics content must be relatively stable before it can be measured normally. In addition, the performance of different manufacturers' meters and the requirements of the tested manufacturers are different. Choosing this type of ultrasonic flowmeter is to have a good idea of the measured medium, but also to have a deep understanding of the performance, accuracy and requirements of the measured medium of the selected ultrasonic flowmeter.

    Portable ultrasonic flowmeter

    It is suitable for temporary measurement, mainly used to check the running status of other flow meters installed on the pipeline, conduct fluid balance test in an area, check the current flow situation of the pipeline, etc. If it is not fixedly installed and used for these purposes, it is convenient and economical to choose a portable ultrasonic flowmeter.

    Time difference ultrasonic flowmeter

    At present, the most widely produced and widely used ultrasonic flowmeter is the time difference ultrasonic flowmeter. It is mainly used to measure the flow of clean fluids and is used in water companies and industrial water applications. In addition, it can also measure the flow of uniform fluids with low acrobatics content (impurity content less than 10g/L, particle size less than 1mm), such as sewage and other media, and the accuracy can reach ±1.5%. Practical applications show that the use of time-difference ultrasonic flowmeters can achieve satisfactory results in the measurement of corresponding fluids.

    In-line ultrasonic flowmeter

    The accuracy is high, which can reach ±0.5%, and it is not restricted by the material and lining of the pipeline. It is suitable for occasions that require high flow measurement accuracy. However, as the pipe diameter increases, the cost will also increase. Under normal circumstances, it is more economical to choose a pipe section type ultrasonic flowmeter with a small and medium diameter. In-line ultrasonic flowmeter: special drilling device can be installed without stopping production. Generally, it is a single channel measurement. In order to improve the measurement accuracy, three channels can be selected. Pipe-segment ultrasonic flowmeter: The pipeline needs to be cut for installation, but the production can not be stopped for future maintenance. Optional single-channel or three-channel sensor. Clamp-on ultrasonic flowmeter: It can complete fixed and mobile measurement. Use special coupling agent (room temperature curing silicone rubber 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 magnetic sensors. Handheld ultrasonic flowmeter: small size, light weight, built-in rechargeable lithium battery, handheld use, with magnetic sensor. Explosion-proof ultrasonic flowmeter: used for liquid flow measurement in explosive environments, explosion-proof and intrinsically safe. That is, the converter is explosion-proof and the sensor is intrinsically safe. Flow measurement system: It is composed of multiple ultrasonic flowmeters and the main station of the system. Suitable for centralized measurement of multiple pipelines.
