Wastewater Level Sensor Submersible Level Transducer Submersible Level Transmitters
Description of Wastewater Level Sensor Submersible Level Transducer Submersible Level Transmitters
Intelligent Submersible Level Transmitter for Diesel Fuel Tanks, Water Tanks, and Liquid Level Monitoring
This advanced transmitter integrates an isolation diaphragm oil-filled sensor and a high-performance MCU. It features automatic linearity correction and temperature drift compensation, with dual output options: digital output (HART protocol) and analog output.
Key Characteristics:
High precision and exceptional stability
Two-way communication for on-site diagnostics
Applications: Municipal power, water conservancy, metallurgy, petrochemical, and related industries.
