ULTRASONIC LIQUID LEVEL METER DATA SHEET FQH-2,FQG-2,FLY An ultrasonic liquid level meter measures the liquid level by the propagation time of the ultrasonic pulses emitted out of the ultrasonic detector are reflected on the surface of the measurement object and are received as echoes by the detector again. It provides high reliability and it permits easy installation, running and maintenance, as it does not make contact with the measurement object and it is free of mechanical moving parts. It deals with uses of a broad range including water level measurement of water, wastewater, tide level, rivers and reservoirs and level measurement of highly viscous liquid in chemical tanks, slurry agitation tanks, roll mills and food tanks. Detector (FQG) FEATURES 1. No liquid contact Permits easy installation and maintenance. 2. Detector of waterproof structure and of excellent corrosion resistance It is of no problem against adhesion of water drops and splashes, and it is optimum for wastewater, alkali, acid and high viscosity liquid. 3. Not affected by fixed reflection noise Not affected by obstacles such as projections of detector mounting area, walls and ladders because of the DGL (dynamic gain limit) function that automatically learns the noise level at all times and masks noise so that no noise is detected. 4. Minimum influence of electrical noise Not affected by electrical noise or noise from agitating blades, as such noise is largely reduced by statistical processing. 5. Use of high gain amplifier Permits use at a pump well involving scum that could be hardly measured with conventional meters and also at a place of large attenuation such as sludge storage tank.
