LWQ series gas turbine meters
       
 

2 Application
LWQ series gas turbine meters are instruments which accurately measure the pipe gas flow rates. It is suitable for measuring the flow rate of natural gas, town gas, propane, butane, ethane, air and N2 etc., because of its high accuracy, it is especially applied to trade measurement and used to be the standard meter which makes measurement value transmission for the gas flow rates.

  
       
 
     
 
       
 

2 Features:
High accuracy, good repeatability, wide working range, simple structure, easy to install and maintain, because it adopts the corrosion resistance material, it has a long service life.
Structure: this series meters are composed of case body, measuring unit and index. The measuring unit is interchangeable after calibration.

2 Volume corrector:
because what the meter measure is the gas volume of the actual temperature and pressure condition, in order to change the actual volume into the standard volume which is in the uniform base condition of the trade two parties, according to the customers’ requirements, our Co. can supply the volume corrector which accurately correct the gas volume..
