Split-type ultrasonic object (liquid) position instrument

I. Product introduction
RSTMH-F/FP split-type ultrasonic object (liquid) level instrument is a convenient and applicable split-type ultrasonic object level instrument developed by our company after years of production experience and absorbing the advantages of many similar products, which solves the trouble of easy failure in the circuit of the all-in-one machine in a bad environment. It has the advantages of accurate measurement, reliable operation and generous appearance. Adopt large scale integrated circuit, component SMT rate up to 90%, ensure the long - term reliability of the product. At the same time, it reduces its power consumption to a very low level. It is easy to get started by using a large screen to display all Chinese menus. It supports SD card data acquisition and serial port data download, and can record ten interference echo-points.
