Embodiment
For shape of the present utility model, structure and feature can be understood better, below will enumerate preferred embodiment and be elaborated by reference to the accompanying drawings.
The technical solution of the utility model provides a kind of external labeling type ultrasonic liquid level measurer, comprise that sonac 1(includes ultrasound wave transmitter module and ultrasound wave receiver module), measurement module 2, power supply and measurement result memory module 3, display module 4 and parameter memory module 6, by initiatively launching ultrasound wave, ultrasound wave is propagated in liquid, between stratified liquid face or in liquid-to-air minute aspect, reflecting, instrument is analyzed echoed signal, calculates the height of storage pot liquid according to the mistiming of echo and transmitted wave.
Sonac 1 is arranged on the container bottom of storage testing liquid, for seeing through container to described testing liquid transmitting ultrasound beamformer, and receives the reflection supersonic wave wave beam from described testing liquid surface reflection.
Power supply and measurement result memory module, for power supply and stores it.
While installing and using the utility model device, sonac 1 is adsorbed onto before container bottom, first container bottom upon adsorption is removed totally, guarantee not have salient point or iron rust.Sonac 1 bottom is smeared even couplant and is adsorbed on container bottom position of center line, guarantees vertical with the liquid level in container.External labeling type ultrasonic device for measuring is opened, selected testing liquid kind, external labeling type ultrasonic liquid level meter will show current level gauging value in 20 seconds.While measuring not preset liquid first, need to first carry out necessary demarcation.When if power feed pilot lamp is bright, charging is in time to guarantee the normal use of equipment.
External labeling type ultrasonic liquid level meter is by controlling the wave beam of the multi-frequency of sonac generation, overcome the energy loss of wall thickness, liquid surface in container produces reflection, reflective sound wave is received by same sensor, by echo being carried out to corresponding high speed signal processing, obtain the height value of liquid in container, its measurement result can directly show.
