The invention relates to an ultrasonic liquid level control system and an implementing method based on Lab VIEW. The ultrasonic liquid level control system structurally comprises a molten steel storage braking device, an ultrasonic sensor is arranged on the molten steel storage braking device, and the molten steel storage braking device and the ultrasonic sensor are sequentially connected with an analog / digital conversion module, a PC (personal computer) / Lab VIEW program module to jointly form an automatic closed-loop control system. The ultrasonic liquid level control system has the advantages that the non-contact type ultrasonic sensor is used for measuring liquid level without contacting with molten steel, and measurement is unaffected by liquid flow and waving or oxidized floats. Movement parts such as lifting platform, a buoy and a lever are omitted. The ultrasonic liquid level control system has the advantages of high measuring accuracy, stable performance, simple structure, easy mounting and demounting and low cost. Amorphous thin belts produced by the ultrasonic liquid level control system are excellent in board model and soft magnetic properties.
Description
technical field [0001] The invention relates to a liquid level control system, in particular to a LabVIEW-based ultrasonic liquid level control system and an implementation method, belonging to the field of material level control. Background technique [0002] Amorphous alloys have excellent soft magnetic properties such as high saturation magnetic induction, high magnetic permeability, low coercive force, and low loss. Amorphous thin strips are widely used in power fields such as distribution transformers and amorphous motors. Amorphous transformers are famous for their It is recognized by the power industry for its energy saving, low carbon, and green environmental protection. It is the best choice to replace traditional oriented silicon steel transformers. [0003] At present, most of the amorphous belt throwing equipment with a high degree of automation control is made abroad. The amorphous and nanocrystalline thin strips of Hitachi Metals Co., Ltd. accounted for nearly...
