Ultrasonic Level Meter
Product Description
Ultrasonic Level Meter
UL7 is non-contact ultrasonic instrument for measuring liquid surface, UL7 usually install on the top of liquid level. Firstly, the sensor emits ultrasonic wave to the liquid surface. Secondly, wave reach to the liquid level and is reflected, sensor receive the echo for processing. Thirdly, the microprocessor will calculate difference of time between ultrasonic emission and receiving, then Convert to distance between sensors to the liquid. Then calculate liquid level through height of tank minus the empty distance (Level = tank height – empty distance)
UL7 liquid-level meter adopts ultrasonic principle to measure the liquid level. Non-contact measurement, effective anti-interference, easy to install, maintain and use.
DESCRIPTION
This instrument determines the height from the bottom to the surface of the liquid under test by measuring the air propagation time, the time required for an ultrasonic wave emitted from the detector installed above the tested liquid to reflect on the level of the liquid, and then return to the detector.
This product can be widely used for a high degree of measurement of the level of a variety of liquid; solid materials can also be used for distance measurement.
FEATURE
-Provides reliable, accurate, and non-contact level measurement
-Non-contact technology offers no moving parts to wear, jam. corrode
-FM approved explosion-proof making it ideal for use in hazardous locations
-Easy programming with 6 digit LCD display and simple menu structure
-Output range is adjustable with choices of inputting tank dimensions or by filling and emptying the tank while calibrating and it automatically and scaling to levels it senses
-Window cover allows easy viewing of display
-Fail-safe output options and diagnostic capabilities
