High-Pressure Electromagnetic Flow Meters: Customized Solutions for Tough Industrial Challenges

In fields such as petrochemical engineering, geological exploration, and high-pressure water injection, flow measurement often faces Extreme pressure, highly corrosive media, and complex installation environments severe challenges. The Zhongce Sensing high-pressure electromagnetic flowmeter addresses these industry pain points by Custom thickened flanges, an innovative external plug-in electrode design, and high-performance PFA/F46 lining , providing a reliable measurement solution for high-pressure, highly corrosive service conditions.

01 Industry Challenges and Core Requirements

In oil exploration, high-pressure water injection in oilfields, and chemical processing, flow measurement instruments often need to be Pressure as high as 25–42 MPa operate continuously under extreme conditions. The media in these environments are often highly corrosive, highly abrasive, or consist of liquid–solid two-phase mixtures, such as mud and corrosive chemical reagents.

These demanding operating conditions place special requirements on flow meters: The structure must withstand extremely high pressure. , to prevent leakage and deformation; The electrodes and lining must resist corrosion and wear. , ensuring the accuracy of long-term measurements; at the same time, the instrument’s Maintain convenience It is also of paramount importance, particularly in continuous production processes where complete shutdowns are difficult to achieve.

The Zhongce Sensing high-pressure electromagnetic flowmeter is specifically designed to address these core requirements, leveraging innovations in materials science and structural engineering to systematically resolve the industry’s key pain points.

02 Custom Thickened Flange: Structural Assurance for High-Pressure Sealing

Flanged connections are the most common connection method in high-pressure piping systems, and their strength directly determines the safety of the entire measurement system under high pressure.

Provided by Zhongce Sensing Full range of custom thickened flanges The material can be carbon steel with zinc spray coating for corrosion protection or stainless steel, to meet the requirements of different pressure ratings and corrosive environments. Depending on the pipe nominal diameter and pressure rating, the flange thickness and structure are specially designed and reinforced.

This customized design ensures that 16 MPa, 25 MPa, and even 32 MPa Under high-pressure conditions, the flange face remains undeformed and the seal maintains its integrity, providing a reliable structural foundation for the entire measurement system.

03 Extrapolated Electrode Design: A Maintenance Revolution and Enhanced Withstand Voltage

The electrode is one of the core components of an electromagnetic flowmeter; however, conventional insert-type electrodes face challenges such as difficult sealing and susceptibility to damage from media-induced impact under high-pressure conditions.

Adopted by Zhongce Sensing Extrapolated Electrode Structure This has fundamentally transformed the situation. Compared with conventional electrode mounting methods, this design significantly enhances electrode voltage withstand capability and assembly efficiency by mounting the electrodes externally.

In actual assembly, technicians can Heat the lining around the electrode assembly points using a hot air gun. , which softens the material to allow easy tightening of the electrode top, thereby achieving greater clamping force and improved sealing performance.

The greatest advantage of this design lies in Maintain convenience —Electrode inspection, cleaning, or replacement can be performed without dismantling the piping, significantly reducing maintenance costs and downtime.

04 PFA and F46 Lining: Dual Protection Against Corrosion and Abrasion

The lining material is in direct contact with the measured medium, and its performance determines the flowmeter’s service life in corrosive and abrasive environments.

Zhongce Sensing high-pressure electromagnetic flowmeters are provided. Two high-performance lining options: PFA and F46 (fluorinated ethylene propylene copolymer) 。

F46 material is in Its chemical stability, electrical insulation properties, and non-stick characteristics are comparable to those of PTFE (polytetrafluoroethylene). , but it offers superior strength, temperature resistance, and low-temperature flexibility.

Most importantly, F46 exhibits better adhesion to metals. It also exhibits superior wear resistance and tear strength, making it particularly well suited for measuring media containing solid particles under high-pressure and high-flow-rate conditions.

05 Selection Guidance and Technical Parameters

To help users accurately select the product best suited to their specific operating conditions, the following is an overview of the core technical parameters of Zhongce Sensing’s high-pressure electromagnetic flowmeters:

06 Application Scenarios and Installation Recommendations

Zhongce Sensing high-pressure electromagnetic flowmeters are specifically designed for Petroleum exploration, geology, or oilfield systems , measuring under high-pressure conditions Mud, high-pressure water injection The volumetric flow rate of the medium.

During installation, to ensure optimal measurement performance and maximum service life, it is recommended to:

Ensure sufficient straight pipe sections upstream and downstream. Typically, the upstream straight pipe section shall be no less than 5D, and the downstream straight pipe section shall be no less than 3D (where D represents the pipe diameter).

Note the dielectric conductivity requirements. , ensure that the conductivity of the medium under test is ≥5 μS/cm.

For split-type flow meters, the distance between the sensor and the converter is Signal cables shall be laid separately. Keep a safe distance from power cables and ensure proper grounding to minimize interference.

Select the appropriate protection rating based on the site environment; for submersible applications, IP68 is available.
