In high-temperature environments, the stability of HHD electromagnetic flowmeters has attracted significant attention. In this test, the HHD electromagnetic flowmeter operated continuously for 1000 hours without failure, demonstrating outstanding performance. Whether LDT-50D, LDC-2A, or the L-MAG series electromagnetic flowmeters, all performed excellently under high-temperature conditions. This report will provide detailed data for technical evaluators to help select reliable flow measurement solutions.

I. Test Background and Industry Requirements

High-temperature environments pose severe challenges to the insulating materials, electrode corrosion resistance, and signal stability of electromagnetic flowmeters. According to the IEC 60751 standard, industrial-grade flow equipment must maintain measurement accuracy of ±0.5% in environments above 80°C. Based on 20 years of sensor R&D experience, Xi'an Shenghongchuang Instrument Co., Ltd. conducted extreme testing on HHD electromagnetic flowmeters. By adopting special alumina ceramic lining and platinum-iridium alloy electrodes, it solved the industry pain point of signal drift in traditional models such as DN18LDE under high-temperature steam media.

III. Application Scenarios and Customer Cases

In a geothermal power generation project in Shaanxi, 5 HHD electromagnetic flowmeters continuously monitored the flow of 180°C high-temperature geothermal water. Compared with traditional LDDC electromagnetic flowmeters, electrode oxidation loss was reduced by 90%. After a chemical enterprise replaced its original DNLDJ model with the L-MAG electromagnetic flowmeter, the stability of acid flow measurement improved by 40%, and annual maintenance costs were reduced by 120,000 yuan. These cases confirm the technological leadership of Xi'an Shenghongchuang products under extreme working conditions.

IV. Technical Guide for Procurement and Selection

Technical evaluators need to focus on three key points: 1) whether the medium temperature exceeds the critical value of 120°C, in which case it is recommended to choose high-temperature dedicated models such as ZYLDE; 2) electrode materials should be selected according to the corrosiveness of the medium, for example, platinum-iridium alloy is suitable for strong acids and strong alkalis; 3) calibration certificates compliant with the ISO 9104 standard must be verified. Xi'an Shenghongchuang provides free sample testing services for multiple models such as LDC-2A, supporting customized solutions for full bore sizes from DN18~DN3000.

V. Industry Development Trends

With the popularization of IIoT technology, electromagnetic flowmeters are developing toward greater intelligence. New-generation products such as LDT-50D have integrated 4G communication and self-diagnosis functions, and the annual growth rate of the high-temperature flowmeter market is expected to reach 8.7% over the next three years. Xi'an Shenghongchuang is developing the L-MAG PRO series resistant to 200°C, which adopts graphene heat dissipation technology and will redefine industry standards.
