- The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
- There are no obstructive flowing parts in the measuring pipe, no pressure loss, and the requirements for straight pipe sections are low.

- The converter adopts surface mount technology (SMT), with self-test and self-diagnosis functions;
- Confirmation of the alcohol flow measurement range
Generally, the flow rate of the measured medium of the industrial alcohol flow meter should be 2~4m/s, and under special circumstances, the minimum flow rate should not be less than 0.2m/s and the maximum should not be greater than 8m/s. If the medium contains solid particles, the common flow rate should be less than 3m/s to prevent excessive friction between the liner and the electrode; For viscous fluids, the flow rate can be selected greater than 2m/s, and the larger flow rate helps to automatically eliminate the effect of sticky matter attached to the electrode, which is conducive to improving the measurement accuracy.
Under the condition that the range Q has been determined, the size of the flowmeter caliber D can be determined according to the range of the above flow rate V, and its value is calculated by the following formula:
Q=πD2V/4
Q: Flow rate (㎡/h) D: Pipe inner diameter V: Flow rate (m/h)
The range Q of the alcohol flow meter should be greater than the expected maximum flow value, and the normal flow value should be slightly greater than 50 of the full scale scale of the flow meter.
- Installation requirements for alcohol flow meters
The protection level of the electromagnetic flow sensor shell is generally IP65 (international GB4208 shell protection level – dust and collision resistance), and the selection of its installation site can be referred to Chapter 5, Section 5. The main requirements for the installation environment are:
(1) The sensor should be installed in a dry and ventilated place, avoid damp and prone to flooding, and avoid direct sunlight and direct rainwater.
(2) It should be avoided as much as possible in places where the surrounding environment temperature is too high. The integrated structure of the alcohol flow meter is also subject to the ambient temperature of the electronic components, which is lower.
(3) There should be no strong leakage current on the pipeline where the sensor is installed, and it should be kept away from equipment with strong electromagnetic fields, such as large electromechanical and large transformers, etc., as far as possible to avoid electromagnetic field interference;
(4) There should be no strong vibration in the pipe or ground where the sensor is installed, especially the integrated instrument;
(5) The location of the sensor installation should consider the space for on-site maintenance by the staff.
Coriolis mass flow meters for distilleries
The application of Coriolis mass flow meters in wineries is mainly reflected in the precise measurement of alcohol content and the optimized control of production processes. Below is a summary of its core application scenarios and technical advantages:
I. Main Application Scenarios
Fermentation Process Monitoring
During the alcoholic fermentation stage, Coriolis mass flow meters monitor the mass flow and alcohol concentration of raw materials (such as fruit juice and malt) in real time to ensure stable fermentation conditions and prevent fluctuations in alcohol content due to temperature or raw material ratio deviations. For example, wineries like Moutai and Wuliangye have installed HK-CMF Coriolis mass flow meters produced by Xiamen Hongkong in the feed pipelines of fermentation tanks to track changes in the density of the fermentation liquid and infer the rate of alcohol production.
Distillation and Refining Control
In the distillation process, the flow meter measures changes in the density of condensed liquid from steam, providing real-time feedback on alcohol concentration improvements, helping to adjust distillation parameters (such as heating temperature and reflux ratio), reduce repeated distillation, and improve production efficiency. For instance, companies like Yanghe Co., Ltd. use it to optimize distillation tower operations, ensuring the liquor reaches the target alcohol content.
Blended Liquor Production
When blending liquors of different alcohol concentrations, Coriolis flow meters synchronize the measurement of the density and flow of multiple raw materials, achieving precise proportion control and avoiding errors from manual blending. For example, the HK-CMF series Coriolis mass flow meters from HOMKOM Hongkong can directly output concentration data for automated adjustment in the blending process.
Bottling and Quality Control
During the final bottling stage, the flow meter ensures the consistency of each bottle’s filled volume through high-precision mass flow measurement (±0.1% ~ 0.5% error) while online density detection verifies whether the alcohol content meets the factory standards.
II. Technical Advantages
Multi-Parameter Synchronous Measurement
It can simultaneously obtain mass flow, density, temperature, and other parameters, and directly calculate alcohol content through the fixed relationship among density, temperature, and alcohol concentration (using lookup tables or built-in algorithms).
Strong Anti-Interference Capability
Made with corrosion-resistant materials (such as Hastelloy) and a sealed design, it can withstand the high acidity of the liquor and is not affected by fluid viscosity, bubbles, or pressure fluctuations.
Non-Intrusive Detection
Measurement can be completed without contacting the liquor, preventing sensor contamination and making it especially suitable for sterile bottling lines and high-end liquor production.
Real-Time and Automation
Data can be transmitted to the control system via industrial buses (such as Modbus), enabling closed-loop adjustments on the production line and reducing the frequency of manual sampling inspections.
