The instrument classification problem, stands in the different Angle of view has the different division method.Some are divided by construction, some are divided by test method, and some are divided by main use. This is also true of vortex flowmeters. People below classify vortex flowmeters from different perspectives.

General classification of vortex flowmeters

According to the interface mode, the interface mode of vortex flowmeter and pipeline can be divided into flange connection type and flange clamping type.Both of these connections have advantages.Flange connection type instrument and connection flange into one, easy to install, but for the factory to improve the machining manufacturing quantity, very is not the same working pressure level, must forge production and processing pressure test level is not the same flange.And flange clamping type vortex flowmeter, both sides without heavy flange, lighter.Under the premise of ensuring that the protruding surface and impact toughness meet the requirements, only the non-flanged surface is manufactured.When applied by customers, flanges with different working pressure levels can be used to connect them according to different pressures.

Second, according to the classification of nondestructive testing technology in nondestructive testing technology, can be divided into thermistor type vortex flowmeter vortex flow meter, ultrasonic vortex street flowmeter, vortex flowmeter, the in-situ stress type capacitance sensor, strain type vortex flowmeter, vortex street flowmeter magnetoelectric (vibration) type vortex flowmeters, optics and optical fiber line type vortex flowmeter and other nondestructive testing technology of vortex flowmeter.This classification method is a conventional classification method for both manufacturers and customers at present, which can reflect the different characteristics of vortex flowmeter from the name.The fifth chapter of this book will introduce the basic principle and characteristics of the vortex flowmeter in detail.

According to different application fields, vortex flowmeters can be divided into flameproof vortex flowmeters, high-temperature vortex flowmeters, ultra-low temperature vortex flowmeters, corrosion resistant vortex flowmeters, inserted vortex flowmeters and mass vortex flowmeters.

According to the structure, the vortex flowmeter can be divided into one type and remote type.

Among them: an all-in-one vortex flowmeter: integrates the controller and the converter (including the flow calculation display information module) into one.The remote type (or separated type) vortex flowmeter refers to the device's controller and converter separated, suitable for unique working standards, such as high temperature vortex flowmeter.

The vortex flowmeter can be divided into basic type and intelligent type according to the function of the instrument.Among them, the intelligent vortex flowmeter is a new steam flowmeter.Its appearance is a reflection of the rapid development trend of sensing technology, electronic information technology and communication technology. This instrument has developed an integrated design scheme at the construction level.At the precise measurement level, the multi-main parameter test is maintained.At the function level, it has several functions such as accurate measurement, compensation, and calculation, self-diagnosis, management method and communication.The intelligent vortex flowmeter indicates the direction of instrument development.

The flow meter can meet the needs of most markets, including water, oil, food, lubricating oil, chemistry, cosmetics, ink, pharmaceutical, coating, petroleum, automobile, glue, polyurethane, electrolyte and additives.
