Thiết bị đo lưu lượng kiểu chênh áp hãng Eureka Eurekone
The EUREKONE FLOWMETER is a new differential pressure flowmeter device that accurately measures flow of various fluids over wide flow range than any other conventional differential pressure flowmeter such as venturies, orifice plates etc. The basic principle is Bernoulli's theorem for the conservation of energy in fluid flow through a pipe. The divergent shape of the cone sensor centered in the line, reshapes the velocity profile to create an improved profile. The configuration of a typical EUREKONE FLOWMETER is showing fig. A/B.
The pressure difference between the static line pressure and the lower pressure created just after the cone sensor can be measured via two pressure sensing taps. One placed slightly upstream of the cone sensor & the other in the downstream face of the cone sensor itself and is related to flowrate through the meter.
