Fuji EDS7-64 Ultrasonic liquid level meter Datasheet

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.
