Coriolis Mass Flowmeter DN25 for LNG Application
Mass flow meters are known for their high accuracy, wide measuring range and reliable performance, and have been successfully used in various industries over the past many years.
Unlike other instruments that are limited to measuring liquids at normal pressure and temperature, ANDISOON excels in measuring under challenging conditions, including high pressure, high viscosity, and high and low temperatures. For example, when measuring CNG (compressed natural gas), the difficulty lies in the high pressure. However, ANDISOON's sensors can withstand high pressures, allowing the necessary increase in flow tube thickness, allowing the transmitter to detect signals with greater sensitivity. Therefore, ANDISOON's mass flow meters specially designed for CNG gas dispensers have been widely used in the domestic market.
In the field of cryogenics, Andisoon has developed a backflow meter and a liquid phase injection meter for LNG refueling stations, with a minimum temperature of -196°C.
In the field of process control, Andisoon has developed a micro-bend type mass flowmeter, with a maximum flow rate of up to 300t/h, widely used in petroleum, chemical and other industrial conditions.

Andisoon low temperarture Coriolis mass flowmeter is to measure deep cold liquids, such as LNG and liquid nitrogen. It is most commonly used for measuring LNG and nitrogen.
Mass flowmeters are widely used in the LNG (Liquefied Natural Gas) industry for accurate measurement and control of the flow of LNG at various stages of the LNG production, transportation, and distribution process. Here are some ways mass flowmeters are used in the LNG industry:
1. Custody Transfer: Mass flowmeters are used for custody transfer measurements to accurately measure the quantity of LNG transferred between parties, ensuring fair and accurate billing.
2. Loading and Unloading: Mass flowmeters are used at LNG terminals for loading LNG onto carriers and unloading LNG from carriers, ensuring precise measurement and control of the flow rates.
3. LNG Production: Mass flowmeters are used in the liquefaction process to measure the flow of natural gas as it is cooled and condensed into LNG.
4. Pipeline Monitoring: Mass flowmeters are used to monitor the flow of LNG in pipelines, ensuring efficient and safe transportation.
5. Storage Tank Monitoring: Mass flowmeters are used to monitor the flow of LNG into and out of storage tanks, helping to manage inventory and prevent overfilling or underfilling.
6. Vaporization: Mass flowmeters are used to measure the flow of LNG during the vaporization process, where LNG is converted back into natural gas for distribution.
7. Process Control: Mass flowmeters are used for process control to ensure that the LNG is flowing at the required rates and pressures throughout the various stages of the LNG production and distribution process.
Overall, mass flowmeters play a critical role in ensuring accurate measurement, control, and safety in the LNG industry, helping to optimize operations and minimize losses.
(1) The Andisoon flow meter uses vacuum brazing technology, ensuring high welding quality while effectively removing stress, significantly improving zero-point stability.
(2) High measurement accuracy: It directly measures the true mass flow, with flow meter accuracy reaching ±0.1%.
(3) High stability: The measuring tube has a small amplitude and can be regarded as a non-moving part. There are no obstructions or moving parts inside the measurement tube.
(4) No requirement for straight pipe sections: It is not sensitive to the velocity distribution of incoming flow, so there is no need for upstream or downstream straight pipe sections.
(5) The measurement values are not sensitive to fluid viscosity, and the influence of fluid density on the flow measurement values is minimal.
(6) The explosion-proof rating exceeds the required level, rated as Ex d ib IIC T6 Gb.
(7) Protection rating: IP67.
(8) The flow meter product has a CPA certificate, including a national-level third-party test report.
(9) Our products are widely used in the oil and petrochemical industries, with stable performance. Case studies are available.
The product has obtained type approval from China Classification Society, ATEX certification, IECEx certification, India PESO certification, and SIL functional safety certification.
(1) For electronic products, we have automatic chip mounter (SMT) production line and high/low temp. testing equipment.
(2) For mechanical products, we have advantage on casting, machining, and welding which is the key point in eyes of Russian.
