FAQs:
  • What media can the HQ-LUGB Vortex Flow Meter measure?
    It is suitable for measuring superheated steam, saturated steam, compressed air, general gases, water, and various liquids, making it highly versatile for industrial applications.
  • How does the temperature and pressure compensation work?
    The flowmeter integrates temperature, pressure, and flow signals. An intelligent digital processor mixes and processes these signals to output a compensated standard flow rate, ensuring accuracy for gas and steam measurements.
  • What is the operating temperature and pressure range?
    The medium temperature range is typically -40°C to +350°C (with options up to +450°C), and the working pressure can be up to 4.0MPa, with higher pressures available upon customization.
  • Is the vortex flowmeter suitable for hazardous areas?
    Yes, explosion-proof versions are available with an explosion-proof mark of Exd I BT4, making them safe for use in potentially explosive environments.
