LUGC Series Gas turbine flowmeter Flow instrument is to draw domestic and foreign advanced technology to optimize the design, synthesis gas mechanics, fluid mechanics, electromagnetics theory and self-developed set of temperature, pressure, flow sensor and intelligent flow totalizer in one of the new generation of high-precision, high reliability gas precision measuring instruments, with excellent low and high pressure metering performance, a variety of signal output and low sensitivity to disturbance of the fluid, is widely used in natural gas, coal gas, liquefied petroleum gas, light hydrocarbon gas and other measuring gas. 

Features: 
Using the new sensors, low starting flow, pressure loss, anti-vibration and anti-pulsating flow properties and difficult to corrosion, reliability and long service life. 
Using the new microprocessor and high-performance integrated chip, high precision arithmetic, the whole powerful, superior performance. 
The use of advanced high-tech micro-power, low power consumption machine. Both the long run with a battery-powered, but also operated by an external power supply. 
By traffic frequency signals can be divided eight automatic meter factor linearity correction, it may be desirable to improve the accuracy of the instrument according to the user. 
It uses EEPROM data storage technology, with historical data storage and query capabilities, three historical data recording mode to choose from. 
High accuracy and good reproducibility. flowmeter meter head can be rotated 180 °, easy to install and use.
