Overview
YI2000 universal ultrasonic material (liquid) level meter is developed and manufactured by our company based on years of application experience.It draws on the advantages of many kinds of position meters at home and abroad.It has realized the design concept of full digitalization and humanization, and has perfect functions of material/liquid level measurement and control, data transmission and man-machine communication.It USES engineering plastic ABS waterproof shell, the shell is small and quite strong.The main chip adopts dozens of relevant special integrated circuits such as imported industrial single chip microcomputer, digital temperature compensation and ultra-wide voltage input voltage stabilization.Modular circuit design, military quality multilayer PCB board, close hardware structure, reasonable layout.Other functions (such as bluetooth, GPRS communication, etc.) can be realized by adding modules according to customers' requirements.With strong anti-interference, can arbitrarily set the upper and lower limit nodes and online output regulation, with field display, can choose analog quantity, switching quantity and RS485 output, convenient interface with related facilities.With high reliability, no pollution, stable performance, without contact with industrial media can meet most of the liquid level, material level measurement requirements.It completely solves the problems of winding, blocking, leakage, medium corrosion and inconvenient maintenance caused by the traditional measurement methods such as pressure type, capacitance type and float type.Therefore, it can be widely used in various fields related to material level and liquid level measurement and control.
