V-cone flowmeter ADF280 Alia Vietnam

Introducing the V-cone flowmeter ADF280 Alia Vietnam

ADF280 series V-cone flowmeter  is a new type of orifice device based on the venturi tube measuring principle and combines the advantages of venturi tube, annular hole plate and wear-resistant hole plate. The sensor has a throttle cone structure with no stagnation zone and has liquid reshaping properties. Its edge is not easy to wear and can maintain long-term precision. There are many types of differential pressure transmitters for you to choose from such as APT9000, APT9500, APT9600. Due to the temperature and pressure compensation function, it can measure the flow of gas, steam, liquid, etc., and is widely used in process control and measurement in petroleum, chemical industry, metallurgy , electric power, heating and water supply.

Characteristics of V-cone flowmeter ADF280 Alia Vietnam

  • High precision and repeatability, wide temperature and turnover rates and
  • pressure compensation
  • Max. The temperature is 500°C; max. Pressure is 100 bar
  • Very wide size selection (15-3000 mm)
  • Measurement of clean/dry liquids, slurries, gases and steam
  • Multi-phase flow can be measured
  • Less requirement for straight pipe spacing upstream and downstream Dirt-resistant, low pressure loss
  • Insensitive to suspended contaminants
