Why need naphtha flow measurement?
Naphtha is also known as chemical light oil and crude gasoline. Naphtha is a colorless liquid at normal temperature and pressure, and insoluble in water. A variety of organic raw materials can be separated from naphtha, such as gasoline, benzene, kerosene, asphalt, etc.
Chemical factories often need to measure the flow rate of naphtha. The flow rate of naphtha is relatively small and the flow rate is slow. Many flowmeters cannot measure accurately. Silver Automation Instrumentation recommends a positive displacement flowmeter-gear flowmeter to accurately measure the volume flow of naphtha/Bizon.
Gear flowmeter to measure the flow rate of naphtha
Gear flowmeter is a new type of positive displacement flowmeter (PD flow meter), used for precise continuous or discontinuous measurement of the flow rate or total flow of liquid in the pipeline. It is a kind of hall flow meter .It is suitable for the flow measurement of high viscosity liquid such as heavy oil, polyvinyl alcohol, and resin, greases, fragrances, adhesives, solvents, inks, polyurethanes, brake fluids, hydraulic oil catalysts, emulsifiers, and pesticides, it can be used as corrosive liquid or hygienic liquid flow meter at low flow rate.
