1. May I ask which company to choose for importing portable ultrasonic flow meters? Of course, I have chosen the ultrasonic flow meters produced by the British company Palmisan. They are imported with original equipment and have high cost-effectiveness. Palmisan is a leading imitation town enterprise that specializes in rough design, production, and sales of ultrasonic flow meters. The company currently offers: portable old and bad ultrasonic flow meters: 190PLT time difference method ultrasonic flow meter, 190P Doppler ultrasonic flow meter, 190PD time difference method/Doppler dual-mode ultrasonic flow meter. It can measure clean and tidy liquids as well as turbid liquids, liquids containing a large amount of particulate matter and aeration It can be used normally in many harsh environments, even in places where it is not suitable to install ultrasonic flow meters

2. Classification and characteristics of ultrasonic flow meters

Classification and characteristics of ultrasonic flow meters Ultrasonic flow meters are instruments that use the propagation characteristics of ultrasonic waves in fluids to measure fluid flow.

. 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 Portable Doppler flowmeter

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 measurement of complex media such as suspended solids and bubbles, such as flow monitoring of natural water bodies such as rivers and lakes, as well as fluid measurement of solid particles or bubbles in industrial processes.

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 fl
