Overview
The HPM4116/4119 series Φ16mm/Φ19mm Ultra-slim Submersible Level Transmitter is a specialized high-precision liquid level sensing solution engineered for groundwater well detection and narrow-space liquid level monitoring, designed exclusively for industrial enterprise users, environmental engineering contractors, and municipal water management operators. Featuring a fully sealed submersible design with an ultra-slim probe diameter of just 16mm or 19mm, this transmitter solves the long-standing challenge of liquid level measurement in narrow boreholes, small-diameter wells, and compact storage tanks where standard level sensors cannot be installed.
At its core, the device employs a high-quality, high-stability pressure sensing element, paired with full-range digital temperature compensation technology to deliver accurate, drift-free measurement data even in harsh underwater environments. The fully welded stainless steel shell and comprehensive potting process ensure reliable hermetic sealing at all connection points, including the probe body and cable, preventing water ingress and extending service life in long-term submerged applications. With an industry-leading IP68 protection grade, this mini diameter submersible level transmitter delivers consistent performance in groundwater monitoring, deep well level measurement, water treatment facilities, and a wide range of industrial process control applications.
Key Benefits
Ultra-compact Slim Design for Limited Installation Spaces
The standout feature of this ultra-slim level transmitter for groundwater well detection is its industry-leading mini diameter probe, available in 16mm (HPM4116) and 19mm (HPM4119) sizes, enabling seamless installation in narrow boreholes, small-diameter wells, and compact tanks with limited access. This eliminates the need for costly well modification or equipment replacement, reducing installation time and labor costs for engineering partners and industrial operators.
High Precision & Ultra-Fast Response
Engineered for rigorous industrial measurement requirements, the device delivers a typical accuracy of ±0.25%FS, with an optional high-precision grade of ±0.1%FS for mission-critical monitoring applications. With a response time of approximately 1ms, it captures real-time liquid level changes instantaneously, supporting rapid process control and emergency alarm triggering for water management and industrial systems.
Superior Environmental Resistance & Long-Term Stability
The fully welded 304/316L stainless steel shell, paired with a double anti-condensation design, ensures reliable performance in extreme temperature conditions, with a medium temperature tolerance range of -40℃ to 80℃. Full-range digital temperature compensation across 0℃ to 70℃ eliminates measurement drift caused by temperature fluctuations, delivering a typical long-term stability of ±0.2%FS per year, with an optional ±0.1%FS per year grade available. The device also withstands 20g mechanical vibration (20~5000Hz) and 20g shock impact (11ms), making it suitable for harsh outdoor and industrial environments.
Flexible Output Options & Comprehensive Protection
With multiple standard output signal options including 2-wire 4~20mADC, 3-wire 0~10VDC/0~5VDC, low-voltage voltage output, and Modbus-RTU/RS485 digital output, the submersible liquid level transducer seamlessly integrates with most PLC, SCADA, and data acquisition systems used by industrial enterprise users. It features full IP68 protection, reverse polarity protection, and compliance with EN 61326 EMC standards, ensuring reliable operation in electrically noisy and high-humidity environments.
