1. What are the options for foreign brands of industrial flow meters?
Foreign brands of industrial flow meters are abundant, and the following is a list of main brands based on technical characteristics and industry applications.
1. European and American brands • Weidun VTON: Coriolis mass flow meters and turbine flow meters have outstanding performance and are suitable for high-precision measurement scenarios in the petrochemical and energy fields.
. Emerson: Differential pressure flowmeter and Micro Motion Coriolis flowmeter (accuracy 0.1%) are industry benchmarks, resistant to high pressure corrosion, widely used in oil and gas and LNG storage and transportation. Endress+Hauser, Germany: The Promass vortex flowmeter is equipped with self calibration technology (Heartbeat), with an accuracy of 0.1% and a pressure resistance of 420 bar, suitable for steam measurement in chemical and power plants. Siemens: SITRANS FUS ultrasonic flowmeter with a range ratio of 100:1, integrated with AI predictive maintenance function, is suitable for regional heating and smart factories. KROHNE, Cologne, Germany: The OPTISONIC series ultrasonic flowmeter is specifically designed for steam and municipal water supply, supporting bidirectional flow measurement. Honeywell: ST series thermal mass flow meters are suitable for extreme temperatures ranging from -200 ℃ to+450 ℃ and are used in the aerospace and nuclear energy fields. • ABB Switzerland: The battery life of electromagnetic water meters is over 15 years, and laser Doppler flow meters are suitable for complex fluids containing particles/bubbles.2. Japanese brand • Yokogawa Electric of Japan: DY vortex flow meters have passed anti vibration certification (ISO 10816 Class A), and dynamic noise suppression technology is suitable for automotive manufacturing and semiconductor ultrapure water systems.
3. Specialized brand in specific fields. • LIT Germany: Electromagnetic and ultrasonic flow meters achieve low flow rate high-precision measurement in the pharmaceutical and beverage industries.
. KNKE from the United States: Turbine and vortex flowmeter are commonly used in new energy battery material production lines for high temperature, high pressure, and corrosive working conditions. Selection suggestion: It is necessary to conduct a comprehensive evaluation based on the characteristics of the medium (such as corrosiveness, cleanliness), operating conditions (temperature, pressure, accuracy), and industry standards. For example, Emerson or Endress+Hauser are preferred for high-temperature and high-pressure chemical scenarios, KROHNE or ABB can be selected for municipal water supply, and VTON or KNKE can be considered for new energy fields.2. What type of flowmeter should be selected for measuring biogas working conditions
Based on different application scenarios of biogas working conditions, I have compiled 5 flowmeter models with strong adaptability and core parameter comparison 1 OPTISONIC 7300 Biogas Ultrasonic Flow Meter - Suitable for dry/wet low-pressure biogas measurement with high CO ₂ content, suitable for landfill and sewage treatment scenarios - Core parameters: single/dual channel optional, flange diameter DN50-200/2-8 inches, maximum pressure rating PN10/ASME Cl 150, range ratio 100:1, integrated gas volume correction and methane content measurement function 2 Heshunda VN Series Turbine Flow Meter - Adaptation Scenarios: Conventional biog
