Insertion type electromagnetic flowmeter: Non-stop installation for large-diameter flow measurement.
In the field of industrial flow measurement, monitoring of large-diameter pipeline flow has always been a challenging issue. Traditional pipe segment electromagnetic flowmeters require cutting the pipeline and shutting down production for installation, which is costly and affects production continuity. However, the emergence of insert-type electromagnetic flowmeters has completely changed this situation with its unique "flow-free installation" advantage. This article will deeply analyze the working principle and outstanding value of insert-type electromagnetic flowmeters, and showcase how Hongqi Automation uses innovative technology to upgrade this product, providing cost-effective measurement solutions for industries such as water supply, metallurgy, and chemical engineering.
1. Insertion-type electromagnetic flowmeter: Re-defining the method for measuring large-diameter flow rates
The insert-type electromagnetic flowmeter is a flow meter that operates based on the principle of electromagnetic induction. Its core design concept is to insert a small electromagnetic flow sensor into the pipeline through drilling, and by measuring the flow velocity at the center of the pipeline or at a specific point, combined with the cross-sectional area of the pipeline, the total flow rate of the entire pipeline can be calculated.
The biggest difference between the pipe segment type electromagnetic flowmeter and the insert type electromagnetic flowmeter lies in that the insert type electromagnetic flowmeter does not require cutting the pipeline or shutting down the production line for installation. It only needs to make an installation hole on the pipeline and use a special tool to achieve pressure-bearing insertion and extraction. This demonstrates an irreplaceable advantage in the application of large-diameter pipelines.
II. Why Choose Insertion-Type Electromagnetic Flowmeter? Four Core Values Stand Out
Significant economic benefits
Cost savings: For large-diameter pipelines with a diameter of DN300 or above, the purchase cost of the insert-type electromagnetic flowmeter is only 1/3 to 1/2 of that of the pipe section type. As the pipe diameter increases, the cost advantage becomes even more significant.
Installation is simple: No complex pipeline renovations are required, and large lifting equipment is largely avoided. The installation time is shortened by over 70%, significantly reducing the installation cost.
Easy maintenance: Supports continuous plug-and-unplug operation. During routine maintenance, calibration, or replacement of sensors, normal production will not be affected.
Excellent applicability
Suitable for large diameters: Specifically applicable to various large-diameter pipelines with a diameter of DN200 and above. It can meet the measurement requirements for pipelines with a diameter of up to DN3000 and even larger.
Adaptability to multiple media: It can measure various conductive liquids such as water, sewage, mud, and mineral slurries. As long as the electrical conductivity is greater than 5 μS/cm, stable measurement can be achieved.
Pressure loss is extremely low: It hardly alters the pipe's flow area and does not cause additional pressure loss, resulting in remarkable energy-saving effects.
Flexible installation method
Ball valve installation: Through the use of dedicated ball valves, pressure-secured installation and disassembly can be achieved, ensuring that instrument maintenance can be completed without production interruption.
Multiple insertion depths: The insertion depth can be adjusted according to the measurement requirements, enabling center measurement of the pipeline or measurement at specific points.
Installation directions are diverse: It supports various installation methods such as horizontal, vertical, and inclined, adapting to different on-site conditions.
Reliable long-term stability
Use wear-resistant and corrosion-resistant electrode materials to adapt to harsh water quality conditions.
Advanced signal processing technology effectively overcomes the influence of flow field disturbances.
The mechanical structure is simple and reliable, with a low failure rate and a long service life.

V. Selection and Application Tips
Installation location selection:
Ensure that the front straight pipe section is ≥ 10D, and the rear straight pipe section is ≥ 5D (D is the pipe diameter).
Electrode maintenance: Regularly check the wear condition of the electrodes and establish a reasonable cleaning cycle based on the characteristics of the medium.
Grounding requirements: Ensure that the fluid in the pipeline is properly grounded to guarantee the stability of the measurement signal.
Safety measures: In cases where the medium contains large solid particles, it is recommended to install a protective cover to prevent the sensor from being damaged by impact.
