Advanced Inline Measurement Solutions for Global Process Industries

Overcoming complex industrial fluid and slurry challenges. Integrate real-time density, viscosity, and concentration tracking into your industry-specific manufacturing pipelines to achieve zero-defect automation.

Industries We Support

LONNMETER helps manufacturers improve process efficiency, product consistency, and real‑time control. Our online and handheld instruments measure density, viscosity, concentration, and moisture with high accuracy.

Our solutions are widely used in industries where real‑time monitoring is critical to process performance and quality control – including mining, food & beverage, chemical, oil & gas, and wastewater treatment. From slurry density in cyclones to sanitary concentration in food lines, LONNMETER delivers reliable data to reduce waste, prevent off‑spec production, and lower costs.

Built for harsh environments, our meters feature advanced sensor technology, easy integration (4‑20mA, Modbus, HART), and low maintenance. ISO, ATEX, and IECEx certified. OEM and private label available.

Let LONNMETER empower your process.
