PACKING & SHIPPING
At Shandong Zhongziyi Intelligent Technology Co., Ltd., we prioritize your satisfaction by committing to deliver your ordered High Reliability Flowmeter with utmost promptness. Our pledge is to meet your specified timelines, ensuring a seamless and efficient service experience every time.
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, i.e., non-pressurized installation allows for the selection of flowmeters without a ball valve.
A hole with a diameter of 50 must be made in the pipeline, and preparations must be made to weld a connecting pipe to the opening.
For situations requiring continuous flow during loading and unloading, or where media overflow is not permitted, a ball valve must be added. This means selecting an insertion-type electromagnetic flowmeter with a ball valve structure.
A hole with a diameter of 50 must be made in the pipeline, and preparations must be made to weld a connecting pipe to the opening.

The requirements for the straight pipe sections are 5D upstream and 3D downstream. This ensures proper use of the electromagnetic flowmeter and meets accuracy requirements.
The measurement principle of the electromagnetic flowmeter does not depend on the flow characteristics.
If 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 measurement.
However, steady-state vortices in the measurement area will affect measurement stability and accuracy.
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, specific lengths for the straight pipe sections upstream and downstream of the flowmeter are required. Otherwise, measurement accuracy will be affected. A straightener can also be installed, and it is advisable to avoid installation close to control valves and partially open valves.
2.2. Requirements for 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, meeting 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 optimal maintenance and performance of the flowmeter, the installation of a bypass pipe is highly recommended. This is particularly crucial in scenarios involving heavily contaminated fluids or when the flowmeter needs to be cleaned without halting the fluid flow. a. Facilitates maintenance of the flowmeter. b. Essential for heavily contaminated fluids. c. Ensures fluid flow continuity during cleaning operations.
3. Installation Requirements for Insertion-Type Electromagnetic Flowmeters
3.1. Requirements for Straight Pipe Sections For accurate measurements, the inlet and outlet straight pipe sections must adhere to the following: Inlet should be ≥ 10×DN; Outlet should be ≥ 5×DN.
3.2. Requirements for Grounding Points To ensure reliable instrument operation and enhance measurement accuracy, it is vital to mitigate the effects of external parasitic potentials. The sensor must be grounded properly with a grounding resistance of less than 10 ohms. (If the metal pipeline is already well-grounded, a dedicated grounding device may not be necessary.)
3.3. Requirements for Installation Position as Illustrated in the Diagram.
