Product Description

Description:

A dual-level mutual calibration water level measurement system (dual-channel full-range level gauge) developed based on the independent intellectual property calculation model. The dual-channel design ensures that there are no blind spots in various working conditions, and can also achieve accurate measurement under harsh working conditions (such as uneven density, surface debris, etc.). The intelligent algorithm has the functions of automatic identification and switching and elimination of abnormal data, and real-time dual-level mutual calibration. When a value jumps or abnormal values appear, the system automatically calculates to ensure data accuracy. The equipment uses static pressure and ultrasonic data as backup to ensure the online rate of the equipment. 

Features:

  • Static pressure + non-contact ultrasonic

  • Dual channel mutual compensation

  • Full range without blind spots

  • Dual channel mutual calibration

  • High accuracy under harsh working conditions

  • Abnormal value and jump recognition and processing function

  • Data security (double data backup)

  • Low power design
