Ultrasonic material level meter

Abstract

The invention discloses an ultrasonic material level meter. The meter comprises a shell, an ultrasonic sensor, a reflecting device and a processor; the ultrasonic sensor is arranged in a vertical direction; an included angle between the ultrasonic sensor and the reflecting device is 45 degrees; the ultrasonic sensor is used for emitting and receiving ultrasonic waves; the reflecting device is usedfor reflecting the ultrasonic waves emitted by the ultrasonic sensor to enable the ultrasonic waves to be vertically emitted to a measured object, and reflecting the ultrasonic waves reflected from the measured object to enable the ultrasonic waves to be vertically emitted into the ultrasonic sensor; and the processor is used for calculating a distance between the ultrasonic material level meterand the measured object. When a liquid level is measured, because the ultrasonic sensor is arranged in the vertical direction, water drops, under the gravity action, are not attached to the outer surface of the ultrasonic sensor; and the whole plane where the outer surface of the ultrasonic sensor is located is coated with a nano coating, and the nano coating is good in water conductivity, therebyeffectively preventing fog on the outer surface of the ultrasonic sensor.

Description

technical field [0001] The invention relates to the technical field of ultrasonic level gauges, and more specifically relates to an ultrasonic level gauge. Background technique [0002] Ultrasonic level gauge is a high-tech product integrating ultrasound, electronics and software. It is the preferred instrument for measuring liquid level and material level in various industrial sites. During the process of level measurement, the ultrasonic wave is sent out by the ultrasonic sensor, reflected by the surface of the liquid or solid material and then returned, received by the same ultrasonic sensor, and the entire running time of the ultrasonic wave is measured, thereby realizing the measurement of the level. [0003] At present, the ultrasonic sensor of the ultrasonic level meter is set horizontally, and the outer surface of the ultrasonic sensor is parallel to the surface of the measured object, that is, the ultrasonic wave emitted by the ultrasonic sensor is directly emitted ...
