ADF280 Series

ADF280 series V-cone flowmeter is a new type of throttle device based on the measurement principle of venturi tube and combining the advantages of venturi tube, annular orifice plate and wear-resistant orifice plate. The sensor with a tapered throttle structure does not have a stagnant zone, and has the characteristics of fluid reshaping. Its edge is not easy to wear, and it can maintain long-term accuracy. There are many types of differential pressure transmitters to choose from, such as APT9000, APT9500, APT9600. Due to the function of temperature and pressure compensation, 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.

FEATURES

High accuracy & repeatability, wide turndown ratio and temperature and pressure compensation The Max. Temperature is 500 °C; the Max. Pressure is 100 bar Very wide selection of sizes (15-3000 mm) The measurement for clean / dry liquids, slurries, gases and steam Measurable for multiphase flow Lower requirements for straight pipe distance on upstream and downstream Dirt resistant, low pressure loss Not sensitive to suspended contaminants
