Jing Chuan LDG type Jilin white liquid flowmeter
I. Product Overview:
Jing Chuan LDG type Jilin white liquid flowmeter Manufacturers are based on fluid Carmen (karman) principle is used to measure and developed into White liquid. A new meter 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, filtering and other measures, greatly improving the product seismic overcome 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 LDG type Jilin white liquid flowmeter Manufacturers are Thermal gas mass flow meter Widely used in large, medium and small variety of pipes and drainage, metering industrial recycling, waste water treatment, oil and chemical reagents as well as compressed air, saturated and superheated steam, gas and a variety of media traffic.
Jing Chuan LDG type Jilin white liquid flowmeter Divided into common type and temperature and pressure compensation type two. Normal refers to a single traffic signal measurements, temperature and pressure compensation type can be achieved simultaneously measure temperature, pressure, flow rate. Each form has split and one-piece two alternatives options to suit different installation and convenient environment.
Second, the principle:
Jing Chuan LDG type Jilin white liquid flowmeter Is spread by direct contact with fluid vortex generator, detection probe and the corresponding electronic circuits and other components. When placed vertically within the fluid flow through the housing vortex generator which generates two rows behind the vortex alternately on both sides (see figure below ), the vortex is called Karman vortex Strouhal on the basis of Karman vortex street theory proposed a velocity proportional to the frequency of Karman vortex fluid, and shows the relationship between frequency and velocity of the 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; (1-1.5d / 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 /)
Fluid sensor is the number of pulses per unit volume of traffic generated by n Qv sensor meter factor called K:
K = (N / m3)
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.
three, Jilin white liquid flowmeter Features:
Jing Chuan LDG type Jilin white liquid flowmeter It has the following characteristics:
