Online Density & Concentration Meter

Density meter is also known as online density transmitter, densitometer, density sensor, density analyzer and inline hydrometer. It's also an instrument to measure concentration of liquids, namely a concentration meter. This online density meter works well in continuous measurement of liquid concentration and density. 

The "plug and play, maintenance-free" inline density sensor is widely applied in industrial production processes, transforming concentration and density meter to corresponding 4-20mA or RS 485 signal. Such density analyzers allow users to monitor real-time concentration and density, reducing costly waste and offering long-lasting stable readings. 

Solutions for Inline Density Meter

Neutralization Process

Neutralization reactions are critical across industries like chemical manufacturing, oil and gas, and mining and metallurgy.

Oil Dry Fractionation

Oil dry fractionation is a physical process used in oil refining industry to separate liquid oils into different fractions based on their melting points.

Alkaline Degreasing

Metal surface preparation requires precise control over concentration in alkali degreasing bath, and rust and paint will be removed easily in hard to reach areas.

Cold Rolling Mill Process

Emulsions serve as lubricants and coolants in cold rolling mill process to reduce friction between rolls and metal surfaces.

Crystallization Monitoring

Crystallization is a critical step in pharmaceutical manufacturing, used for the purification and formulation of APIs.

Wort Boiling

Wort boiling is a critical step in brewing, performed in a wort pan or with an external boiler (shell or plate heat exchanger).

Titanium Dioxide Post Treatment

Titanium Dioxide (TiO2, titanium(IV) oxide) is used as white pigment in paints and lacquers, as well as UV blocker for sunscreen products.

Formaldehyde Synthesis

The synthesis of formaldehyde demands precise control over the inline concentrations of methanol and formaldehyde to ensure product quality.

Benfield Process

The Benfield Process is a cornerstone of industrial gas purification, widely adopted in chemical plants to remove carbon dioxide (CO2) and hydrogen sulfide (H2S) from gas streams.

Amine Scrubbing

Amine scrubbing, also known as amine sweetening, is an essential chemical process to capture acid gases like CO2 or H2S.

Phase Seperation

Precise caprolactam concentration measurement is essential for efficient caprolactam production processes.

Dry Chlorine Scrubber

Wet chlorine gas (Cl₂) produced from brine electrolysis contains moisture that must be removed to ensure purity and prevent corrosion.
