This report presents professional tests on the stability of the TC-DCGD electromagnetic flowmeter under high-temperature environments, verifying its core performance as an industrial-grade flow control device. As a technological benchmark in the field of electromagnetic flowmeters, the TC-DCGD, together with the HY-LD and ZK-LDE series products, constitutes a precise measurement and control solution, particularly suitable for flow monitoring needs under harsh operating conditions.

I. Testing Background and Industry Challenges

In high-temperature operating environments such as chemical, metallurgical, and energy industries, traditional electromagnetic flowmeters often face problems such as measurement drift and electrode aging. Xi'an Shenghongchuang Instrument Co., Ltd., based on 20 years of sensor R&D experience, has launched the TC-DCGD series of high-temperature electromagnetic flowmeters. These flowmeters feature ceramic lining and tantalum electrodes, extending their operating temperature range to -40℃ to 180℃, offering 60% better temperature resistance than conventional models such as the ZK-LDC. This test, conducted according to GB/T 18659-2018 and IEC 60770 standards, simulated stability under a continuous high-temperature environment of 130℃.

II. Key Performance Test Data

III. Comparative Analysis with Competitors

Compared to the PTFE lining of the Magne electromagnetic flowmeter, the TC-DCGD uses an alumina ceramic lining, which reduces the coefficient of thermal expansion by 42% at 130℃. Compared to models like the HK-LDE that use rubber seals, its metal bellows sealing structure extends its lifespan to over 5 years. Especially in highly corrosive media environments, the tantalum electrode exhibits significantly better corrosion resistance than the 316L electrode of the LDG electromagnetic flowmeter.

IV. Analysis of Typical Application Scenarios

(1) Molten salt energy storage system: In the molten salt heat exchange circuit at 550℃, the W3000 PLUS signal converter achieves a measurement accuracy of ±0.3%; (2) Petrochemical cracking unit: It forms a dual-redundant system with the TC-ZNDC explosion-proof model and has passed SIL2 certification; (3) High temperature wastewater treatment: Its acid and alkali resistance is better than that of the MGG electromagnetic flowmeter and it has been applied to 30 hazardous waste treatment projects.

V. Recommendations for the Selection of Technical Assessment Personnel

It is recommended to prioritize the following parameter matching: ① Whether the medium temperature exceeds 120℃; ② Whether SIL/ATEX certification is required; ③ Conductivity threshold requirements (TC-DCGD supports ultra-low conductivity of 1μS/cm). For alternatives, the ZK-LDE economic model can be considered when budget is limited, but this requires accepting approximately a 15% sacrifice in accuracy.
