High Precision and Strong Adaptability: A Guide to the Correct Installation and Industry Applications of Electromagnetic Flowmeters

This article provides a detailed introduction to the installation steps, environmental requirements, and common application scenarios of the insertable electromagnetic flowmeter, helping users in industries such as water treatment, chemical engineering, pharmaceuticals, and water processing to achieve high-precision and high-stability flow monitoring, and improve the operational efficiency and reliability of the system.

1.Why choose the insertable electromagnetic flowmeter?

The insert-type electromagnetic flowmeter is a device widely used for measuring the volumetric flow of conductive liquids and slurry in closed pipelines. Its prominent advantages include:

• Applicable to various media, including industrial wastewater, underground sewage and other conductive liquids;
• Offers high-precision measurement and excellent repeatability;
• Supports bidirectional flow detection, making it an ideal choice for leakage detection and energy management.

This instrument is widely used in fields such as water treatment, chemical industry, pharmaceuticals, environmental protection, and municipal waterworks. It is particularly suitable for situations involving medium to large pipe diameters and those where pipe rupture is not likely to occur.

2.Key Points for Selecting Installation Environment and Location

(1)Installation environment requirements

• It should be kept away from strong electromagnetic field devices to avoid signal interference;
• The installation location should be free from strong vibrations and the environmental temperature should not fluctuate too much;
• It must be convenient for daily maintenance and debugging.

(2)Selection of installation location

• It is necessary to ensure that the pipeline is always filled with fluid;
• The length of the upstream straight pipe section is recommended to be greater than 8 times the pipe diameter ( 8D), and the downstream section should be no less than 5 times the pipe diameter ( ≥ 5D) to ensure stable flow.

3.Detailed Explanation of Sensor Installation Steps

• Cleaning and Preparation: Remove the welding slag and burrs from the installation base, and ensure the sealing surface is smooth.
• Installation of Ball Valve and Positioning: Install the DN50 ball valve on the base with the cavity facing upwards. Confirm that the operation is flexible.
• Inserting the Sensor: Insert the sensor into the pipeline through the ball valve. The insertion depth is recommended to extend 3mm beyond the base.
• Adjusting Direction and Tightening: Make sure the direction mark of the sensor is consistent with the flow direction of the fluid. Make the initial fixation and then make the final adjustment.

4.Precautions for Welding and Electrical Connections

• The base welding must use stainless steel welding rods to ensure that the flange surface is parallel to the pipe axis, avoiding internal forces or poor sealing;
• Electrical connections should be carried out strictly in accordance with the instructions. After powering on, it is necessary to confirm that the zero-flow display is zero. During normal flow, adjust to the maximum value and lock it.

5.Industry Applications and Core Strengths

The insert-type electromagnetic flowmeter is particularly suitable for the following scenarios:

• Fluid monitoring and batch control in the pharmaceutical industry;
• Flow monitoring of municipal sewage and drinking water;
• Industrial circulating water and energy management systems.

Its high precision, large diameter applicability and ease of installation make it the preferred flow meter for many complex working conditions.
