Vortex flowmeter
Overview
Vortex flowmeter is a new type of intelligent flow meter designed by Karman vortex street principle and magnetoelectric induction principle, and developed by using magnetoelectric digital signal detection technology. The product has the characteristics of high sensitivity and low power consumption, and can be widely used in petroleum, chemical, metallurgy, brewing, printing and dyeing, medicine, food, environmental protection and other industries.
Working principle
It is designed according to the principle of Karman vortex street and magnetoelectric induction. When the medium flows through a trapezoidal cylinder vortex generator, two regular rows of cross arranged vortices will be released alternately on both sides of its downstream, and the separation frequency of vortices is directly proportional to the flow rate within a certain speed range.
Composition
It is composed of sensor and converter, which integrates flow measurement and local display, and is equipped with a variety of standard output signal interfaces.
Functional features
Ø Dual power supply design, internal 3V ~ 3.6V lithium battery or external 24 VDC power supply, can also supply power at the same time;
Ø Intelligent integrated design, powerful function, can be displayed on site, and convenient for users to read and modify parameter settings;
Ø Signal output function: 4 ~ 20mA current output, RS-485 communication and other standard interfaces;
Ø With good anti vibration and anti-interference ability;
Ø The sensor is made of stainless steel, corrosion-resistant, no moving parts inside, long service life;
Ø Low flow limit, wide range ratio and high measurement accuracy.
Main parameters
Ø Nominal diameter (mm): DN15~DN300;
Ø Nominal pressure (MPa): 1.0, 1.6, 2.5, 4.0, 16, 25, 32, 42;
Ø Accuracy grade: 1.0 and 1.5;
Ø Working voltage:(internal)2.7V~3.6VDC; (external) +18V~+36VDC;
Ø Output signal: 4-20mA current output and pulse output of standard two-wire system;
Ø Communication interface: RS-485, RS-232C, MODBUS, REMOTE(HART)
