The LWQ series gas turbine flowmeter is an advanced instrument that is widely used in the petroleum, chemical, electric power, metallurgy, and civil boiler industries for gas metering. The device integrates a gas turbine flow sensor and flow converter, and its primary performance indexes have reached an international advanced level, making it an ideal choice for gas metering in various industrial applications.

The flowmeter comes equipped with a cutting-edge sensor that allows it to measure even the smallest flow. It also boasts minimal pressure loss, excellent anti-vibration and anti-pulsation flow performance, and corrosion resistance, all of which contribute to its reliability and durability.

When gas enters the flowmeter, it undergoes an initial acceleration via the independent movement of the leading fluid. Upon encountering the turbine blades at a certain angle, the gas generates a rotating torque that overcomes resistance and friction torque, initiating turbine rotation.

When equilibrium is reached, the turbine's rotational speed and flow rate become linearly related. A rotating sender disc on the magnet periodically alters the sensor magnetic resistance, producing a pulse signal proportional to the volume of fluid flow at both ends of the sensor.

The converter amplifies and shapes this signal, while pressure and temperature signals detected by the pressure and temperature sensors are simultaneously transmitted to the flow totaliser for processing. The flow totaliser then directly presents the standard volumetric flow rate and the standard volumetric total.

  • The flowmeter's new microprocessor and high-performance integrated chip work together to improve its computing precision, making it a powerful and superior device that you can rely on.
  • The flowmeter's advanced micro-power technology ensures low power consumption, allowing it to run on a long-term power supply with an internal battery or an external power source, providing you with flexibility and versatility.
  • The flowmeter automatically linearly corrects the coefficient of the instrument up to eight segments based on the flow frequency signal, which enhances the accuracy of the instrument according to your specific needs.
  • The flowmeter uses EEPROM data storage technology, allowing for historical data storage and query function. You have the option to choose from three different historical data recording methods, making it a flexible and customizable solution for different applications.
  • The flow meter head's 180° rotation capability provides you with more flexibility during installation and maintenance, making the process more efficient and straightforward.
  • The flowmeter's high accuracy, with a measurement range of ±1.5%R, ±1.0%R, ensures you get precise readings every time.
  • The flowmeter's excellent repeatability, with a short-term repeatability of up to 0.05% R to 0.2% R, guarantees that you can rely on it for consistent and dependable results.
  • The flowmeter detects the temperature, pressure, and flow of the measured gas and automatically tracks the flow compensation, displaying the standard state (Pn = 101.325KPa, Tn = 293.15K) gas flow. It also allows for real-time query of temperature, pressure, time, date, and other data, giving you more control over the measurements and contributing to a more efficient and effective workflow.
