Introduction

This report presents an in-depth performance test of the CGRD electromagnetic flowmeter under high-temperature conditions, with a focus on verifying the stability of its insert-type PTFE lining design under extreme operating conditions. As a professional manufacturer of flow control equipment, Xi'an Shenghongchuang Instrumentation Co., Ltd. uses rigorous experimental data to analyze for you the precise performance of BFG-S, LDBE and other series of electromagnetic flowmeters in high-temperature liquid flow monitoring, helping industrial users solve the challenges of high-temperature medium measurement.

In the field of industrial flow measurement, liquid flow monitoring under high-temperature conditions has always been a technical challenge. Traditional flowmeters are prone to measurement errors, material aging and other issues under high-temperature conditions, affecting the accuracy of production data and the service life of equipment. With years of technical expertise, Xi'an Shenghongchuang Instrumentation Co., Ltd. has developed the CGRD series electromagnetic flowmeter, featuring a special insert-type PTFE lining design that can effectively address the challenges of measuring high-temperature media.

Core Technical Features of the CGRD Electromagnetic Flowmeter

1. Unique Insert-Type PTFE Lining Design

The CGRD electromagnetic flowmeter adopts an innovative insert-type PTFE rubber lining structure, which demonstrates significant advantages in high-temperature environments. The PTFE rubber material has excellent high-temperature resistance and can maintain stable physical properties within the temperature range of -50℃~250℃. Compared with traditional rubber linings, the PTFE rubber lining does not deform or age under high-temperature conditions, ensuring long-term reliability in use.

The insert-type design makes installation and maintenance more convenient, allowing users to inspect or replace the flowmeter without interrupting pipeline operation. This feature is particularly suitable for industries such as petrochemicals and electric power, where production shutdowns are not easy. At the same time, the insert-type structure reduces fluid resistance and lowers energy consumption, reflecting the energy-saving concept of modern industrial equipment.

2. Measurement Stability in High-Temperature Environments

The CGRD electromagnetic flowmeter uses special signal processing technology, effectively solving the problem of unstable electromagnetic fields in high-temperature environments. Our tests show that in a high-temperature liquid environment of 150℃, the measurement error of this flowmeter is only ±0.5%, far below the ±1% required by industry standards.

To verify this performance, Xi'an Shenghongchuang simulated various high-temperature operating conditions in the laboratory, including:

• Temperature cycle test: 100 cycle tests conducted within the range of 80℃~200℃
• Long-term high-temperature stability test: continuous operation for 1000 hours in an environment of 180℃
• Temperature shock test: sudden increase from room temperature to 200℃ to check response speed

In all tests, the CGRD electromagnetic flowmeter demonstrated excellent stability and repeatability, proving its reliability as a high-end flow control device.

Performance Test Methods and Results

1. Test Environment and Conditions

This test was conducted in Xi'an Shenghongchuang's standard laboratory, using a professional temperature control system and flow calibration device. The following parameters were strictly controlled in the test environment:

During the test process, precision temperature sensors and standard flowmeters were used as references to ensure the accuracy and reliability of the data. Comparative tests were carried out on different models of electromagnetic flowmeters, including BFG-S, LDBE, UHLDG and other series products.

2. Analysis of Key Performance Indicators

Through systematic testing, we obtained the following key data:

• At a high temperature of 200℃, the zero-point drift of the CGRD electromagnetic flowmeter is less than 0.1%/10℃
• Range error remains within ±0.5% at 150℃
• Signal response time is less than 50ms, meeting the requirements of rapid measurement
• After 1000 hours of continuous operation, accuracy attenuation is less than 0.2%

These data fully prove the excellent performance of the CGRD electromagnetic flowmeter in high-temperature environments. Especially compared with the conventional ZB and ZA series, CGRD shows significant improvement in high-temperature stability.

Application Recommendations Under High-Temperature Working Conditions

1. Installation Precautions

Although the CGRD electromagnetic flowmeter has outstanding high-temperature resistance, in order to ensure optimal measurement performance, we recommend that users pay attention to the following installation points:

• Avoid installation in positions directly exposed to heat source radiation
• Maintain sufficient upstream and downstream straight pipe sections （front 10D rear 5D）
• The grounding system must comply with IEC 60364 standard requirements
• Use high-temperature-resistant cables to connect signal lines

2. Maintenance and Care

Equipment maintenance is particularly important in high-temperature environments. For electromagnetic flowmeters such as DH-LDE and JY-LDE, it is recommended to:

• Check the electrodes and lining condition every 3 months
• Carry out a calibration inspection once a year
• Pay attention to the temperature alarm information on the display screen

Xi'an Shenghongchuang provides customers with professional maintenance training and regular equipment inspection services to ensure that your flow control system always remains in optimal condition.
