Ultrasonic air velocity meter, FLOWSIC60

 
 

The FLOWSIC60 ultrasonic measuring device uses ultrasonic signals to continuously measure air velocity in tunnels and shafts. The rugged measuring device consists of high-quality stainless steel components and is ideal for use in harsh environments. Once installed, the FLOWSIC60 continuously and automatically measures air velocity across the entire tunnel cross section and displays the measurement result via the analog output, making integration in monitoring systems simple. Because safety underground is top priority, the FLOWSIC60 is intrinsically safe and certified for use in mining according to IECEx. Low maintenance, wear-free operation and integrated self-monitoring offer a high degree of safety and convenience for air flow measurement in explosion proof areas.

At a glance

  • Continuous air flow measurement
  • Intrinsically safe with IECEx approval for zone 0 (EPL Ma)
  • Ultrasonic technology with no moving parts
  • Representative measurement across the entire tunnel cross section
  • For tunnel diameters from 0.5 m to 8.5 m
  • Stainless steel components and cable protective tubing for a long service life in harsh environments
  • Integrated self-diagnostics
  • Analog output with error current output

    Your benefits

  • Safe operation by intrinsically safe measuring system
  • Automatic air flow measurement
  • Reliable results by measurement across the entire tunnel cross section
  • Long service life due to the use of durable stainless steel components and the wear-free measurement principle
  • Low operating costs due to minimal maintenance work and integrated self-diagnostics
  • Reduced installation and commissioning effort due to flexible mounting positions and simple electrical installation
  • Low maintenance and long service intervals due to no moving parts and high tolerance to contamination
  • Easy connection to monitoring and control systems via analog measurement signal

    Fields of application

  • Air flow measurement in explosion proof areas
  • Measurement of the supply and exhaust air in mines
  • Ventilation monitoring and control in mining shafts and tunnels
