PACKING & SHIPPING
At Shandong Zhongziyi Intelligent Technology Co., Ltd., we pride ourselves on our commitment to excellence. Our dedicated team ensures that your High Precision Electromagnetic Flowmeter with Anti-Vibration and Good Repeatability is delivered promptly and precisely according to your specifications. Experience unparalleled efficiency and reliability with our timely service.
The installation of the High Precision Electromagnetic Flowmeter with Anti-Vibration and Good Repeatability from Shandong Zhongziyi Intelligent Technology Co., Ltd. varies depending on the site pipeline conditions. For flowmeters without a ball valve, installation should be on a non-pressurized pipeline, ensuring a seamless setup.
Create a 50mm diameter hole in the pipeline and prepare to weld a connecting pipe to this opening. This step is crucial for ensuring the stability and functionality of the flowmeter.
For applications requiring continuous flow during loading and unloading, or where media overflow is not permissible, it is necessary to incorporate a ball valve. This entails selecting an insertion-type electromagnetic flowmeter with a ball valve structure to maintain precision and control.
As previously noted, a 50mm diameter hole must be made in the pipeline, and preparations for welding a connecting pipe to the opening are imperative for proper installation.

The flowmeter requires straight pipe sections of 5D upstream and 3D downstream. This configuration ensures optimal performance and accuracy, aligning perfectly with stringent measurement standards.
The electromagnetic flowmeter operates independently of the flow characteristics, delivering consistent and reliable measurements.
If turbulence and vortices occur in the non-measurement area of the pipeline (caused by elements like elbows, tangential throttling, or partially open shut-off valves upstream), they will not affect the measurement accuracy. The design is robust enough to handle such disturbances.
However, steady-state vortices within the measurement area can compromise both stability and accuracy. Specific measures should be taken to mitigate this effect.
To stabilize the flow distribution, consider the following adjustments:
1.2. Pipeline-type electromagnetic flowmeter
2.1. Requirements for straight sections To mitigate the effects of vortices and distortions in the flow field, adhere to specific lengths for the straight pipe sections upstream and downstream of the flowmeter. Proper alignment ensures measurement accuracy and reliability. A flow straightener may also be considered, and avoid installing the flowmeter close to control valves and partially open valves.
2.2. Requirements for the process pipes The flowmeter has precise requirements for the upstream and downstream process pipes at the installation point to maintain accuracy. a. Ensure the inner diameter of these pipes matches the sensor: 0.98DN ≤ D ≤ 1.05DN (where DN is the sensor's inner diameter, and D is that of the process pipe). b. The process pipe and sensor must be concentric, with an axial deviation not exceeding 0.05DN.
2.3. Requirements for Bypass Pipes To ensure seamless maintenance of the flowmeter, it is highly recommended to install a bypass pipe. This becomes crucial when dealing with heavily contaminated fluids or in circumstances where the flowmeter needs cleaning without halting fluid flow. a. Facilitates easy maintenance of the flowmeter. b. Essential for handling heavily contaminated fluids. c. Allows cleaning without stopping the fluid flow.
3. Installation Requirements for Insertion-Type Electromagnetic Flowmeters
3.1. Requirements for Straight Pipe Sections Ensure optimal performance by adhering to the following straight pipe section requirements: Inlet should be ≥ 10×DN; Outlet should be ≥ 5×DN.
3.2. Requirements for Grounding Points To guarantee reliable operation and enhance measurement accuracy, the flowmeter must be protected from external parasitic potentials. The sensor requires effective grounding with a resistance of less than 10. (If the metal pipeline is already well-grounded, an additional grounding device is unnecessary.)
3.3. Requirements for Installation Position Refer to the provided diagram for precise installation positioning.
