LWQ Series Gas Turbine Flowmeter
Inquiry
Product introduction
The LWQ Series Gas Turbine Flowmeter measures gas flow based on the kinetic energy principle. Incoming gas is first conditioned by an inlet flow straightener, which eliminates swirl, turbulence, and asymmetry, creating a laminar flow profile. The conditioned gas then impinges on a multi-blade turbine rotor, causing it to rotate. The rotational speed of the rotor is directly proportional to the gas velocity. An inductive or magnetic sensor detects the rotor's movement and outputs a frequency signal corresponding to the volumetric flow rate. When equipped with temperature and pressure sensors, the meter can compute standardized flow (Nm³/h) via real-time compensation algorithms.
Physical Properties
★ Integrated Temperature and Pressure Compensation: Ensures accurate standard volume flow measurement under varying operating conditions.
★ Wide Display Range: Segment LCD readable at ambient temperatures down to -30°C, showing real-time flow rate, cumulative flow, pressure, and temperature.
★ Digital Pressure Transmitter: Enables high-resolution pressure measurement and compensation.
★ Compact Integrated Design: Combines sensing, compensation, and display functions in a single instrument body, simplifying installation.
★ RS485 Modbus Communication: Standardized digital protocol for SCADA, DCS, and IIoT systems.
★ Optional Outputs: Pulse, analog (4–20 mA), and frequency outputs available for remote monitoring and control.
★ High Accuracy and Repeatability: Suitable for custody transfer and process gas measurement.
★ Low Pressure Drop: Streamlined flow path reduces system backpressure, ideal for compressed gas systems.
