The installation of the electromagnetic flowmeter from Shandong Zhongziyi Intelligent Technology Co., Ltd. varies depending on the site pipeline conditions. Flowmeters without a ball valve should be installed on a non-pressurized pipeline, allowing for the selection of flowmeters without a ball valve.
A precise hole with a diameter of 50mm should be made in the pipeline. Prepare to weld a connecting pipe to the opening to ensure a secure and efficient installation.
For applications requiring continuous flow during loading and unloading or where media overflow is not permitted, a ball valve must be integrated. This necessitates the selection of an insertion-type electromagnetic flowmeter designed with a robust ball valve structure.
A precise hole with a diameter of 50mm should be made in the pipeline. Prepare to weld a connecting pipe to the opening to ensure a secure and efficient installation.

The straight pipe sections are crucial for accurate measurements: 5D upstream and 3D downstream are required to ensure the proper function and precision of the electromagnetic flowmeter.
The sophisticated measurement principle of the electromagnetic flowmeter is unaffected by the flow characteristics, offering dependable accuracy.
If turbulence and vortices arise in the non-measurement area of the pipeline (e.g., elbows, tangential throttling, or a partially open upstream shut-off valve), the measurement remains unaffected.
However, steady-state vortices within the measurement area can impact the stability and accuracy of the readings. Addressing these issues is essential for maintaining precision.
In such cases, specific measures should be implemented to stabilize the flow distribution:
1.2. Pipeline-type Electromagnetic Flowmeter
2.1. Requirements for Straight Sections To reduce the effects of vortices and flow field distortion, adhere to specific requirements for the lengths of straight pipe sections upstream and downstream of the flowmeter. Install straighteners when necessary, and avoid placing the flowmeter near control valves or partially open valves.
2.2. Requirements for the Process Pipes The flowmeter has stringent requirements for the upstream and downstream process pipes at the installation point. a. The inner diameters of the upstream and downstream process pipes must match that of the sensor, adhering to the condition: 0.98DN ≤ D ≤ 1.05DN (where DN is the sensor's inner diameter, and D is the process pipe's inner diameter). b. Ensure the process pipe and sensor are concentric, with an axial deviation not exceeding 0.05DN.
2.3. Requirements for Bypass Pipes To ensure seamless maintenance and efficient operation of the flowmeter, it is highly recommended to install a bypass pipe. Specifically, in scenarios involving heavily contaminated fluids and when the flowmeter needs to be cleaned without interrupting the fluid flow, a bypass pipe becomes essential. a. Facilitates the maintenance of the flowmeter. b. Absolutely necessary for heavily contaminated fluids. c. Allows for cleaning the flowmeter without halting fluid flow.
3. Installation Requirements for Insertion-Type Electromagnetic Flowmeters
3.1. Requirements for Straight Pipe Sections To achieve optimal performance, the straight pipe sections for the inlet and outlet must have specific lengths: The inlet should be at least 10 times the pipe diameter (≥ 10×DN), and the outlet should be at least 5 times the pipe diameter (≥ 5×DN).
3.2. Requirements for Grounding Points For the instrument to operate reliably and deliver precise measurements, it must remain unaffected by external parasitic potentials. Ensure the sensor is properly grounded with a grounding resistance of less than 10. (If the metal pipeline is already well-grounded, a dedicated grounding device is not needed.)
3.3. Requirements for Installation Position Please refer to the accompanying diagram for precise installation positioning guidelines.
