In the field of circular gear flow meters, choosing a reliable factory depends on its technical expertise, manufacturing capabilities, and understanding of specific operating conditions. Our company’s instruments have 60 years of experience serving strict fields such as nuclear power, while Xiamen excels in deep customization to meet special needs. When selecting, it is necessary to clarify key issues such as accuracy, material, and working conditions to ensure precise matching.

In the field of circular gear flow meters, choosing a reliable factory depends on its technical expertise, manufacturing capabilities, and understanding of specific operating conditions. Based on the market situation in 2026, we recommend the following source factories with expertise in technology, quality control, or service.
If you are pursuing absolute reliability that has been verified through long-term and extreme working conditions,
Core advantage: As a well-established enterprise with over 60 years of history, it has a profound technological foundation.
Manufacturing capability: We have over 600 sets of professional processing equipment, as well as provincial-level technical centers and Anhui Province flow instrument calibration stations, ensuring quality control throughout the entire process from research and development to factory calibration.
Application verification: Its products have long served in fields with extremely strict equipment requirements such as PetroChina, Sinopec, and nuclear power. For example, the LC-OI50 elliptical gear flowmeter has won the National Excellent Gold Award and has been successfully applied to national key projects such as power plants.

If your working conditions are particularly special and require highly customized solutions, Meikong’s flexibility and deep customization capabilities are outstanding.
Core advantages: With independent modern production bases and CNAS accredited laboratories, we adhere to 100% real flow calibration to ensure the precise measurement of each equipment.
Customization capability: Supports comprehensive non-standard customization of body materials (304/316 stainless steel, PTFE), gear materials (304, PEEK), pressure rating (up to 20MPa), process connection methods, and output signals.
Service response: Implement the “Three Ones” service system (one phone response, one hour initial response, and one day problem-solving), and the technical team can provide full process support from selection to after-sales training.
Selection key: List of communication with the factory
When communicating with the above or any factories, it is recommended to clarify the following questions in order to screen out suppliers that truly match your needs:
Accuracy and Calibration
What is the guaranteed accuracy of this model when measuring my specific medium (such as 5000 mPa · s resin)? Is it an indication error or a full-scale error? ”
Does every unit undergo real flow calibration before leaving the factory? Can you provide a complete verification report and calibration curve? ”
Material and compatibility
What material are the components of the flowmeter that come into contact with the medium (body, gear, sealing ring)? Please provide material certification.
Is this material fully compatible with my media (such as strong acids, food ingredients)? ”
Adaptability to working conditions
My process pressure is X MPa, temperature is Y ℃, and the medium contains trace solid particles. Are there corresponding models for pressure resistance, temperature resistance, and wear resistance? ”
What is the minimum startup flow? Can you meet my low traffic metering needs? ”
Service and Delivery
What is the delivery time for standard products? Does it support non-standard customization? ”
