Description
Ultrasonic level meter uses sound waves to measure liquid or solid level. Fast, accurate measurements are possible in the field or anywhere without the use of down-hole water level meters. The Ultrasonic Level Meter are lightweight, compact, versatile, and easy to operate. As long as the obstructions take up no more than half of the bore area the meter will not suffer any loss of accuracy.
Ultrasonic level meter is composed with the designed in the integrative ultrasonic wave sensor and electronic unit. The meter installs on the top of the container, under the control of the electronic unit, the sensor launches a bunch of ultrasonic pulses to the things of tested. Sound wave is reflected by object surface; parts of reflected return waves echo are received and change into the electric signal. The time of launching ultrasonic wave to receiving it again is direct ratio to the distance of sensor to the things of tested. The electronic unit measures the time, and calculates out the distance examined according to the known velocity of sound. Then draw the location value of things through subtraction operation.
Ultrasonic wavespread speed among gas is influenced by gas temperature, when the meter works , it measures gas temperature needed, compensates for the velocity of sound, so as to ensure the precision of measuring. While the meter launches the ultrasonic pulse, it can’t measure the return waves at the same time. One short distance downward from sensor is Blind Space. If the supreme thing location examined enters the blanking distance, the instrument can’t measure correctly, then error. If needed, we can count the meter and increase to install.
