PACKING & SHIPPING
We are committed to delivering your ordered product at the earliest date as per your requirements, ensuring timely and efficient service.
The installation of the electromagnetic flowmeter varies depending on the site pipeline conditions. Flowmeters without a ball valve should be installed on a non-pressurized pipeline. This non-pressurized installation allows for the selection of flowmeters without a ball valve.
A hole with a diameter of 50 mm should be made in the pipeline. Preparations should be made to weld a connecting pipe to the opening in the pipeline.
For situations requiring continuous flow during loading and unloading or where media overflow is not permitted, a ball valve must be added. This necessitates selecting an insertion-type electromagnetic flowmeter with a ball valve structure.
A hole with a diameter of 50 mm should be made in the pipeline. Preparations should be made to weld a connecting pipe to the opening in the pipeline.

The requirements for the straight pipe sections are 5D upstream and 3D downstream. This ensures the proper use of the electromagnetic flowmeter and meets the accuracy requirements.
The measurement principle of the electromagnetic flowmeter does not depend on the characteristics of the flow.
If a certain amount of turbulence and vortices are generated in the non-measurement area of the pipeline (such as elbows, tangential throttling, or a partially open shut-off valve upstream), it will not affect the measurement.
However, if there are steady-state vortices in the measurement area, it will affect the stability and accuracy of the measurement.
In this case, some measures should be taken to stabilize the flow distribution:
1.2. Pipeline-type electromagnetic flowmeter
2.1. Requirements for straight sections To mitigate the effects of vortices and flow field distortion, there are specific requirements for the lengths of the straight pipe sections upstream and downstream of the flowmeter. Otherwise, measurement accuracy will be affected. A flow straightener can also be installed, and it is advisable to avoid installation close to control valves and partially open valves.
2.2. Requirements for the process pipes The flowmeter has specific requirements for the upstream and downstream process pipes at the installation point. Otherwise, measurement accuracy will be affected. a. The inner diameter of the upstream and downstream process pipes should be the same as that of the sensor and must meet the condition: 0.98DN ≤ D ≤ 1.05DN (where DN is the inner diameter of the sensor, and D is the inner diameter of the process pipe). b. The process pipe and the sensor must be concentric, with an axial deviation not exceeding 0.05DN.
2.3. Requirements for Bypass Pipes To ensure seamless maintenance and optimal performance of the flowmeter, it is highly recommended to install a bypass pipe. This is particularly crucial when dealing with heavily contaminated fluids or scenarios where the flowmeter needs cleaning without interrupting the fluid flow. a. Facilitates easy maintenance of the flowmeter. b. Essential for heavily contaminated fluids to ensure resilience and longevity. c. Allows for uninterrupted cleaning of the flowmeter, preserving the fluid flow.
3. Installation Requirements for Insertion-Type Electromagnetic Flowmeters
3.1. Requirements for Straight Pipe Sections Inlet/Outlet Straight Pipe Sections: To maintain precision and efficiency, ensure that the inlet section is at least 10 times the pipe diameter (≥ 10×DN) and the outlet section is at least 5 times the pipe diameter (≥ 5×DN).
3.2. Requirements for Grounding Points For reliable operation and enhanced measurement accuracy, the sensor must be well-grounded to avoid external parasitic potentials. The grounding resistance should be less than 10 ohms. (Note: If the metal pipeline is already well-grounded, a dedicated grounding device is not necessary.)
3.3. Requirements for Installation Position Please refer to the accompanying diagram for optimal installation positioning to ensure maximum efficiency and accuracy.
