Features
● Multi-medium Measurement: Realizes non-contact level detection of liquid, paste and granule materials (>4mm), with adaptive measurable ranges for high-temperature vapor and solid media.
● Accurate Level Reading Under Fluctuation: Four adjustable change rates ensure precise measurement of the average liquid level even when the liquid level fluctuates drastically.
● Diverse Display Modes: Six display modes available, including real-time echo waveform and 3-minute historical curve display for intuitive level data monitoring.
● Real-time Temperature Compensation: Internally integrated temperature sensor provides automatic sound speed compensation, improving measurement accuracy under temperature changes.
● Convenient On-site Operation: Configured with an LCD screen and physical keyboard for direct on-site parameter setting and data viewing, no additional debugging equipment required.
● 4~20mA Current Diagnostic Function: Allows quick detection of current output faults, simplifying on-site troubleshooting and maintenance.
● Multilingual & Unit Support: Switchable English/Chinese display, with meter and inch length units optional for global industrial application.
● Intelligent Anti-interference: Automatically detects on-site electrical disturbance and active interference suppression, ensuring stable data output in complex electromagnetic environments.
● Comprehensive Electrical Protection: All input and output lines are designed with overvoltage and overcurrent protection, effectively preventing equipment damage from electrical faults.
● Alarm Current Output: Configurable alarm current (3.8mA/22mA) and safety distance setting, triggering automatic alarm when the liquid level enters the blind area to avoid industrial accidents.
● Flexible Installation: Three installation modes (bracket, flange, plastic screw nut) with customizable flange specifications, adapting to different tank/pool structures.
● Adjustable Core Parameters: Supports flexible setting of damping time, threshold voltage, sound speed and other parameters, matching complex on-site working conditions.
● Long Service Life: Non-contact measurement avoids direct contact with the measured medium, reducing wear and tear and lowering equipment failure rate.
Applications
It is an ideal choice for level monitoring in chemical, water treatment, food processing, building materials, and storage and transportation industries, with a long service life and low maintenance cost to meet the diverse level measurement needs of industrial sites.
