Due to its cost efficient features the ultrasonic sensor liquid level measurement has gradually become recognized as an excellent potential cost-saving source for customers. First of all, its non-intrusive design guarantees that the liquid will not be polluted, which is essential in all areas requiring the utmost cleanliness. Secondly, since there are no moving parts maintenance is little, thus reducing costs in time. MaxBotix began producing an ultrasonic sensor with contamination-free design; its different from all other sensors and can measure in most liquids on the market today in real time using high-resolution capacitive technology. Thirdly, universal feed sensors are designed with a degree of flexibility, letting them handle a wide range of liquid types including resin types and so on which could damage other types of sensor if exposed to these substances. Moreover, the installation is simple and need not shut down production; therefore, only minor disturbances will occur. In addition, it makes possible accurate measurements under severe conditions. Even in the worst environment for these products, such as overspill cases where there might be few or no signals at all from a transmitter to receiver.
