1. Introduction:
HF ultrasonic level gauge contains a number of patented technology, with safety, clean, high accuracy, long life, stable and reliable, easy installation and maintenance and other characteristics, suitable for acid, alkali, salt, corrosion, high temperature and other fields.
HF ultrasonic level gauge can be connected to the display table or various DCS systems through 4~20mA or RS485(Modbus protocol or other custom protocols), providing real-time liquid level data for industrial automation. The meter
 
2. Technical features:
Circuit design from the power supply part of the choice of high quality power module, components choose imported high stability and reliable devices, can completely replace the same type of foreign imported instruments.
Patented sound wave intelligent technology software can carry out intelligent echo analysis, without any debugging and other special steps, this technology has the function of dynamic thinking, dynamic analysis.
My company has the acoustic intelligent patent technology, so that the precision of the meter is greatly improved, the liquid level precision up to 0.3%, can resist all kinds of interference waves.
This instrument is a non-contact instrument, does not contact directly with the liquid, so the failure rate is low. The instrument provides a variety of installation methods, the user can fully calibrate the instrument through this manual.
All the input and output lines of the instrument have the protection function of lightning protection and short circuit protection.
