1. Classification and Characteristics of Ultrasonic Flow Meter
Classification and Characteristics of Ultrasonic Flow Meter Ultrasonic flow meter is an instrument that uses the propagation characteristics of ultrasonic waves in fluids to measure fluid flow rate. According to different measurement principles, application scenarios, and types, ultrasonic flowmeters have multiple classifications, each with its unique characteristics and applicable scenarios.
1. Classification based on measurement principles. Characteristics of time difference ultrasonic flowmeter: Time difference ultrasonic flowmeter calculates the flow rate by measuring the time difference between the propagation of ultrasonic waves in the fluid, and then obtains the flow rate.
. This method is suitable for measuring liquids with turbidity ≤ 20000ppm and low bubble content that are single, uniform, and capable of transmitting ultrasonic waves. It has high measurement accuracy and good adaptability to changes in the physical properties of fluids, such as temperature and pressure. Application: Widely used for flow measurement of liquids such as clean water, tap water, purified water, and sewage. Characteristics of Doppler method ultrasonic flowmeter: Doppler method ultrasonic flowmeter uses the scattering effect of scatterers (such as solid particles, gas bubbles, etc.) in the fluid on ultrasonic waves to measure flow velocity. When ultrasound encounters scatterers in a fluid, a frequency shift (Doppler effect) occurs, and the flow velocity can be calculated by measuring this frequency shift. This method is suitable for measuring multiphase flow media containing solid particles, bubbles, etc. Application: Commonly used for flow measuremen_600x400.jpg)
2. Classification of Fixed Ultrasonic Flowmeters by Application: Fixed ultrasonic flowmeters are usually installed on industrial pipelines for online measurement of fluid flow.
. It has the advantages of accurate measurement, good stability, and easy maintenance. Application: Widely used for fluid flow measurement in industries such as petroleum, chemical, power, metallurgy, etc. Characteristics of Handheld Ultrasonic Flow Meter: Handheld ultrasonic flow meters are portable, flexible, and easy to operate. It is usually used for comparison and inspection measurement of online flow meters, which can quickly and accurately obtain fluid flow data. Application: Suitable for situations that require frequent movement of measurement points, such as flow monitoring in water supply, heating, drainage, and other systems.3. Classification by type. Characteristics of split type ultrasonic flowmeter: The split type ultrasonic flowmeter consists of a sensor and a main unit. The sensor is installed on the fluid pipeline, and the main unit can be installed in a convenient location for observing data or in a better environment as needed.
. This type is suitable for installation in high-altitude or underground locations where it is inconvenient to observe data or in harsh environments. There are various forms of host for split type ultrasonic flow meters, such as wall mounted, disk mounted, modular, explosion-proof, etc., which can be selected according to actual needs. Application: Widely used for fluid flo
