Description

MH-GAultrasonic level measuring instrument, taking the advantages of various many level measuring instruments, is a universal one characterized by total digitized and humanized design. It has perfect level monitoring, data transmission and man-machine communication. The master chip is imported technical m single chip with relevant application specific ICs such as digital temperature compensation. It is featured by strong anti-interference performance, free setting of upper and lower limits and online output regulation, on-site indication, optional analog, switching value, and RS485 output and easy connection with main unit. The cover, made of waterproof engineering plastics, is small and firm with PP probe. Its main circuit board applies quality SMT components and keyboard, making it more stable and reliable. Therefore, it is applicable for various fields concerning level measuring and monitoring.
