Abstract

The invention relates to the technical field of measuring equipment, in particular to an ultrasonic level meter which comprises a first shell, a second shell, a third shell and a fourth shell. The second shell is arranged in the axial direction of the first shell, and a driving mechanism connected with the power supply structure is arranged in the second shell; and the arc-shaped structure is arranged at the bottom of the second shell. The ultrasonic level meter provided by the invention is accurate in measurement result.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to an ultrasonic level gauge. Background technique [0002] The working principle of the ultrasonic liquid level gauge is that the transducer sends out ultrasonic pulses, which are reflected back when encountering the surface of the measured medium, and part of the reflected echo is received by the transducer, converted into an electrical signal by a piezoelectric crystal or a magnetostrictive device, and The distance between the sensor and the surface of the liquid to be measured is calculated from the time between the emission and reception of the sound wave. Due to the use of non-contact measurement, the measured medium is almost unlimited, and can be widely used to measure the height of various liquids and solid materials. Ultrasonic water level gauge adopts advanced microprocessor, has unique echo processing technology, has false echo storage function, built-in tem...
