LUGB type vortex flowmeter 一、Overview:
  LUGB type vortex flowmeter is a natural shock-type that a non-streamlined flow of pipeline fluid components inserted in the fluid ,when the flow velocity is big enough , in the downstream of components in the flow will have a whirlpool, and the frequency of whirlpool have a linear relationship over a wide range with the media vellocity.
  There is no removable mechanical parts ,long life ,little maintenance ,Coefficient of Instrument is stable ,and easy to guarantee precision in any working environmant . Having from the low-temperature -40 ℃ to 350 ℃ high temperature of a wide working temperature range. We could used it with Flow totalizer to measure steam, air, gases and liquids in general a variety of media, such as the volume of flow and mass flow, is a better flow measurement instrumentation.

二、Features:
·With simple and firmly structure ,no removable parts ,high reliability ,it is stable to applicate for a long term .
·Non-zero drift, high accuracy
·Low Pressure loss and low operating costs
·Installation is simple, easy to maintenant
·Wide measuring range, range ratio up to 1:15
·Wide application range ,it can measure the flow value of gas ,liquid ,steam .
·Wide operating temperature range: -40 ℃ to 350 ℃ of high temperature
·Output pulse signal or current signal, easy to corollarily use with computers and other digital.

三、Main technical parameters
·Measuring medium:
  a、Liquid : Cold water, hot water, a variety of petroleum products, liquefied petroleum gas, liquid oils of various chemical .
  b、Gas: Compressed air, oxygen, natural gas, liquefied petroleum gas and a variety of chemical gases .
  c、Saturated steam and the temperature lower than the superheated steam of 350℃ .
·Measuring the extent possible: Reynolds number is 5000 ~ 7000000 .
·Normal working range :Reynolds number is 20000 ~ 7000000 .
·Accuracy :Liquid is ±1%;gas、steam is±1.5% .
