I. Product Overview:

Jing Chuan JC-LUGB Vortex flowmeter is based on fluid Carmen ( karman ) Principles, and developed into a new type of meter used to measure gas, vapor or liquid flow, and as flow transmitters used in automation and control systems. The series meter uses advanced differential technology, with isolation, shielding and filtering measures, greatly improving the earthquake resistance, overcoming the small signal data disorders and other problems, and uses a unique sensor packaging technology and protective measures to ensure the reliability of the product. Fine River JC-LUGB Vortex flowmeters are widely used in large, medium and small variety of pipes and drainage of industrial wastewater treatment cycle oil and chemical reagent metering, as well as compressed air, saturated and superheated steam, gas and a variety of media traffic.

Jing Chuan JC-LUGB Vortex Flowmeter divided into common type and temperature and pressure compensation type two. Normal refers to the measurement of a single traffic signal, temperature and pressure compensation type can be achieved simultaneously measure temperature, pressure, flow rate. Each form has split and one type two options to accommodate and facilitate the different installation environment.

Second, the principle:

Jing Chuan JC-LUGB Type vortex flowmeter is spread by direct contact with fluid vortex generator, detection probe and the corresponding electronic circuits and other components. When the vertical vortex generator placed in the fluid flow through the housing, alternately produce two columns on both sides behind Whirlpool (see below), this vortex is called Karman vortex. Strouhal on the basis of Karman vortex theory proposed the Karman vortex frequency is proportional to the flow rate of the fluid, and gives the frequency and velocity The relationship equation:

Where: f- vortex separation frequency (HZ); U

within u- line fluid average velocity (m / s); f = `Sr

d- vortex generating body facing the flow width; (1-1.25d / D)

D- inner diameter of the sensor housing;

Sr- Strouhal number, a dimensionless number. For certain cylindrical vortex body occurs within a certain flow range is a function of the Reynolds number in the range of the normal flow can be considered constant.

From the above equation, the flow in the vortex generator welcome width d and Strouhal number Sr is known conditions, it can be determined the average velocity of the fluid in the pipe and volume flow Qv U by measuring the vortex shedding frequency

Qv = 3600`Uπ (D / 2) 2

Fluid sensor is the unit volume flow Qv The number of pulses generated n Called the sensor meter factor K :

n

K= ( N / m 3 )

Q

Alternating force generated by the swirl on the detection probe, so that the internal embedded piezoelectric element generates a charge frequency signal detected by the pre-conversion processing electrical amplification, the output is proportional to the volume flow of the pulse signal, or replace the standard signal output connected with flow indicator and temperature, the pressure sensor, calculates various parameters, display and cumulative like.
