摘　　要：VSCT型智能化硫酸浓度计,是根据谐振原理,通过对90%～95%硫酸密度的测定,再利用硫酸"浓度-密度-温度"间的函数关系,确定其浓度。该表具有抗干扰能力强,测量准确可靠,线性化输出等优点,并有自检、防死机、上下限报警和数字显示等功能。The VSCT concentration meter for the determination of 90～95% H_2SO_4 was developed. It is based on measuring the density of acid by means of resonance and then according to the correlation function of concentration-density-temperature to determinate the H_2SO_4 concentration. The meter is characterized by outstanding antijamming, percise and reliable determination and linear output,and has the function of self-checking,dead-halt prevention,upper and lower limit alarming and digital display.
