What are the types of ultrasonic flow meters? Ultrasonic flowmeter is an instrument that uses ultrasonic technology to measure fluid flow rate. It has the advantages of non-contact, pollution-free, high precision, and high reliability, and is widely used in industrial, environmental protection, water conservancy, petroleum, chemical and other fields. According to different application scenarios and measurement requirements, ultrasonic flow meters can be divided into the following types:
1. Habitual ultrasonic flow meters: Habitual ultrasonic flow meters adopt the single channel measurement principle, and calculate the flow rate and flow chamber turbulence by the time difference of ultrasonic propagation between the transmitter and receiver. It is suitable for general liquid flow measurement, such as tap water, sewage, petroleum, chemical industry, etc.
2. Multi channel ultrasonic flowmeter: Multi channel ultrasonic flowmeter adopts the multi-channel measurement principle, which can simultaneously measure the flow of multiple pipelines and is suitable for parallel flow measurement of multiple pipelines, such as thermal stations, water pump rooms, etc.
3. Portable ultrasonic flowmeter: Portable ultrasonic flowmeter has the characteristics of small volume, light weight, easy operation, etc., suitable for on-site flow measurement and detection, such as water conservancy, environmental protection, petroleum and other fields
4. Gas ultrasonic flowmeter: Gas ultrasonic flowmeter adopts the sound velocity difference method or Doppler effect principle, suitable for gas flow measurement, such as natural gas, coal gas, air, etc.
5 Liquid gas dual-purpose ultrasonic flowmeter: The liquid gas dual-pu
2. How is the internal structure layout of the SICK ultrasonic flowmeter?
The internal structure of the SICK ultrasonic flowmeter revolves around the ultrasonic detection core and is divided into three functional modules: signal acquisition, processing, and fluid channel. The layout is compact and optimized for industrial site stability.
. 1. The internal structure of SICK ultrasonic flowmeter is divided into three core areas with relatively fixed positions: • The fluid measurement chamber and transducer module are located in the old fluid flow area of the cover code at the bottom/front end of the equipment, which is the core detection unit Contains 2 (or more) sets of ultrasonic transducers, installed in pairs in flange mounting seats on both sides of the pipeline. Some pipeline models use Z-shaped, V-shaped, or W-shaped installation layouts to ensure that the ultrasonic beam can penetrate the measured fluid. two Internally, a fluid diversion and rectification structure will be installed to reduce the interference of turbulence on ultrasonic signals and improve measurement accuracy. The signal processing and control module is located in a closed cavity at the upper part of the device and is the computing core of the entire machine Equipped with a dedicated ultrasound signal transceiver chip, responsible for sending ultrasound pulses, receiving
