The QMF is a fixed QStar ultrasonic flow meter model. The use of multiple processors working in parallel means that QStar achieves an extremely high measurement rate. Signal processing takes place in high performance DSPs which are extremely precise and operate at very high resolution. This enables the device to achieve internal resolution of under 0.001 m/s flow velocity. And since the transit time measurement is purely digital, the measurement electronics are virtually drift and calibration-free.-40 to 300 deg F, 2 MHz transducerOperation - intuitive via 8 main keys (soft keys), plain text displayPrinciple - ultrasonic transit time difference with AFC technologyDiagnostic functions - acoustic velocity, signal strength, SNR, signal quality, amplitude and energy, oscilloscope function allows graphical display and analysis of signalsLanguages: English, Spanish and FrenchValues measured - flow, flow speed and heat flowAdjustable 0 - 100 sec signal dampingHeat quantity, volume totalizersFor measuring tasks over an extended period of time and continuous measurements in fixed installations.
