Aiming at the deficiency of traditional liquid level measurement technology in practical application, a new design scheme of liquid level sensor is proposed. The scheme uses magnetostrictive principle to transform the measurement of liquid level information into accurate timing of signal pulse. By analyzing the structure and working principle of magnetostrictive liquid level sensor, this paper describes the system construction, hardware circuit design and software programming in detail, and especially, gives the basic frame and steps of magnetostrictive transducer and high precision time measurement scheme. Experiments show that the liquid level sensor based on magnetostrictive principle has the advantages of stable operation, high measurement accuracy and digitization, and has certain practical value.
