An online concentration meter is an instrument used to monitor and control fluid concentration in real time. It can continuously measure and display the concentration of fluid. Online concentration meters are usually installed in pipelines or storage tanks in industrial production processes to monitor and control the concentration of various liquids or slurries to ensure the stability of the production process and product quality.
Types of concentration meter
Alcohol concentration meter
An alcohol concentration meter is an instrument specially used to measure alcohol concentration. It measures alcohol concentration based on the density of alcohol solution changing with concentration. There is a certain correspondence between the density of the alcohol solution and its concentration. By measuring the density of the solution, the concentration of alcohol can be obtained.
Typical Application:
Large and medium-sized breweries, industrial alcohol production, medical alcohol production
Tuning fork concentration meter
The tuning fork concentration meter is a density measuring instrument based on the principle of vibration, used for online monitoring of the concentration of liquids. It works through a tuning fork sensor inserted into the liquid. The tuning fork sensor consists of two vibrating fork arms. Its vibration frequency changes with the change in the density of the liquid. Tuning fork densitometers measure the concentration of a liquid by detecting this tiny change.
Typical application:
Food and beverage industry, pharmaceutical industry, chemical industry, petroleum and petrochemical industry, water treatment industry, metallurgical industry, rubber and plastic industry, coating and ink industry.
Chemical concentration meter
A chemical concentration meter is a critical measurement tool specifically designed to accurately monitor the concentration of chemicals in liquids. The instrument can be integrated into an online process monitoring system or used as a precision laboratory analysis device. Because its sensing fork is made of corrosion-resistant materials, it can be reliably used to detect the concentration of various corrosive chemical solutions, ensuring stability and durability under harsh working conditions.
Typical Application:
Chemical industry, petroleum and petrochemical industry, food and beverage industry, pharmaceutical industry, water treatment industry, environmental monitoring, automotive industry, battery manufacturing industry.
Refractive index concentration meter
A refractometer is an instrument based on the principle of refraction that is used to measure the concentration of solutes in liquids. Its working principle is based on the phenomenon of refraction of light as it passes from one medium into another. When light passes from air into a liquid, the relationship between the angle of incidence and the angle of refraction is described by Snell's law. Different liquids have different refractive indexes, and the refractive index of a liquid is related to its chemical concentration. Therefore, by measuring the refractive index, the concentration of solute in the liquid can be obtained.
Typical Application:
Food industry, brewing industry, chemical industry, pharmaceutical industry, water quality monitoring, oil and gas industry.
Ultrasonic concentration meter
Ultrasonic concentration meter is an instrument that uses the principle of correlation between the propagation speed of ultrasonic waves and the density of the medium to measure the concentration of solutes in liquids. Its working principle is to send ultrasonic waves of a certain frequency through the liquid being measured, and then receive and analyze the propagation characteristics of these sound waves.
Typical Applications:
Petrochemical industry, food industry, pharmaceutical industry, cement manufacturing, pulp and paper industry, water quality monitoring, metallurgical industry.
Advantages of concentration meter
High accuracy
A tuning fork concentration meter can provide very accurate concentration data because its measurement principle is based on physical constants, such as vibration frequency, which are relatively insensitive to changes in temperature and pressure.
Non-contact measurement
Tuning fork concentration meters usually use non-contact measurement methods, which means they do not require direct contact with the substance being measured, thus avoiding problems of contamination and wear.
Adaptable
Tuning fork concentration meters can be used in a variety of different situations, including high temperatures, high pressures, corrosive or viscous liquids, and environments with high hygiene requirements.
Real-time monitoring
Tuning fork concentration meters can monitor the concentration of substances in real time, which is very important for process control and product quality monitoring.
Easy maintenance
Tuning fork concentration meters generally have low maintenance requirements because they have no moving parts, are not easily damaged, and are easy to clean and calibrate.
Easy to install
Tuning fork concentration meters are usually relatively simple to install and do not require complex piping or bracketing systems.
Application of concentration meter

Brewing industry
Alcohol concentration meters are now widely used in many brewing industries to measure alcohol readings. It can quickly and accurately measure the alcohol content in wine, avoiding the cumbersomeness and inaccuracy of traditional methods. It can also monitor the fermentation process of wine in real time and adjust process parameters in a timely manner, thereby accelerating the production cycle, improving production efficiency, and ensuring the stability of product quality.

Food processing
The tuning fork concentration meter is a density measuring instrument based on the principle of vibration, used for online monitoring of the concentration of liquids. It works through a tuning fork sensor inserted into the liquid. The tuning fork sensor consists of two vibrating fork arms. Its vibration frequency changes with the change in the density of the liquid. Tuning fork densitometers measure the concentration of a liquid by detecting this tiny change.

Pharmaceutical Industry
Tuning fork concentration meters provide high-precision and high-resolution measurements. This is very important for the pharmaceutical industry, because concentration control during the production process directly affects the quality and performance of the final product, ensuring product consistency and stability. It provides more convenience and possibilities for production process control in the pharmaceutical industry.

Water quality monitoring, water treatment
The concentration meter can monitor water quality in real-time and provide continuous concentration data, helping to adjust the water treatment process promptly to ensure that water quality is stable and up to standard. It usually uses non-contact measurement, which avoids contamination problems caused by direct contact and also reduces maintenance workload. Made of 316 stainless steel, the fork body is partially anti-corrosion treated to better resist corrosion and is suitable for various highly corrosive water quality monitoring occasions.
Archimedes' principle
That is, the buoyant force on an object in a liquid is equal to the weight of the liquid it displaces. When a concentration meter is immersed in liquids of different densities, it floats up and down until it reaches an equilibrium point. The scale corresponding to this equilibrium point can represent the density of the liquid, and the concentration value can be calculated from the density.
principle of refraction
The concentration of a solution is determined by measuring the change in the angle of light as it passes from one medium (such as air) into another medium (such as the solution to be measured). When light strikes the solution interface at a certain angle, refraction occurs. The size of the refraction angle is related to the refractive index of the solution, and the refractive index is a function of the solution concentration.
Optical rotation phenomenon
That is, when plane-polarized light passes through certain organic compound solutions, the vibration plane of the light will rotate. This angle of rotation is proportional to the concentration of the solution. Therefore, by measuring the optical rotation, the concentration of a solution can be determined indirectly.
Conductivity
Assess the concentration of a solution by measuring its conductivity. The conductivity of a solution is related to its ion content, so for a solution of known composition, its concentration can be determined by measuring the conductivity.
pH value
The concentration meter based on this principle mainly measures the pH of the solution, but actually measures the hydrogen ion concentration of the solution. It usually contains a sensitive electrode (such as a glass electrode) and a reference electrode to determine the negative logarithm of the hydrogen ion concentration (i.e. pH) by measuring the potential difference.
Optical principles
Optical densitometers use a light source of a specific wavelength to illuminate a solution and measure the intensity of transmitted or reflected light. The concentration of the solution can be calculated and calibrated from these optical data.
