Precision LWGY Type Tibet's temperature and pressure compensated flowmeters
Precision LWGY Type Tibet's temperature and pressure compensated flowmeters Manufacturers are based on fluid Carmen (Karman) developed by the principles used to measure The temperature and pressure compensation. Gas, steam or liquid flow in a new type of flow meter, and can be used as flow transmitters used in automated control systems. The series flow meter using advanced differential techniques, combined with isolation, shielding, filtering measures, greatly improving the seismic resistance of the product, issues such as overcoming the small signal data disorder, and introduced a unique sensor packaging technology and protective measures to ensure the reliability of the product. Precision LWGY Type Tibet's temperature and pressure compensated flowmeters Gas turbine flowmeter Manufacturers are widely used in large, medium and small pipes and drainage, industrial recycling, sewage, oil and chemicals, as well as compressed air, saturated and superheated steam, gas and a variety of medium flow measurement.
Precision LWGY Type Tibet's temperature and pressure compensated flowmeters Divided into two types: ordinary type and temperature and pressure compensation. Common type refers to the measurement of a single flow signal, temperature and pressure compensation can be temperature, pressure, and flow measurement. Each form has split and submerged two choices to accommodate and facilitate the installation of different environments.
Second, the principle of work:
Precision LWGY Type Tibet's temperature and pressure compensated flowmeters Is by direct contact with fluid Vortex generator and detection probes and electronic circuits and other components. When the fluid flows through the shell when the vertical vortex generators, on the sides of the rear two alternately swirls (see the following figure), this whirlpool is called Carmen swirl. Siteluohaer on the basis of the Karman Vortex Street proposed a Karman Vortex frequency is proportional to the velocity of the fluid, and the relationship between frequency and velocity equation:
In the formula: f-Vortex separation frequency (HZ); U
U-tube fluid velocity (m/s); f = 'Sr
D-whirlpool width; (1-1.5d/D)
D-the sensor shell diameter;
Sr-strouhal number, dimensionless number. For certain column spiral body, within a certain flow, is a function of the Reynolds number, can be assumed to be constant throughout the normal flow.
The above shows that, in Vortex generator width d and strouhal number Sr for known conditions, can be determined by measuring the frequency of vortex pipe in the volume flowrate of fluid velocity u and Qv
Flow sensor flow Qv producing pulses per unit volume n factor called sensor k:
K= (N/ m3 )
Produced by whirlpool alternating force acting on the probe, the inner laying of the charge of the piezoelectric element frequency signal, detected by the front electrical amplification conversion processing, pulse signal output is proportional to volumetric flow, or into a standard output signal. Connected with the flow indicator and temperature, pressure sensors, various parameters of operations can be carried out, display and new threat definitions.
