IP68 Submersible Hydrostatic Level Transmitter 4-20mA

Submersible Hydrostatic Level Transmitter 4-20mA, 0-10m Range IP68 Water Level Sensor for Fire Tank, Pool, River

This submersible hydrostatic level transmitter (model QDY30A-PB) is designed for continuous liquid level measurement in tanks, pools, rivers, and industrial environments. It uses a high-precision diffused silicon sensor with 0.5% accuracy and an IP68 waterproof housing for direct immersion. The standard 4-20mA output signal is compatible with most PLC, DCS, and display meters, making it ideal for fire protection systems, water treatment, and groundwater monitoring.
