As a technical evaluation specialist in the field of flow-control equipment, are you concerned about the performance of the MGG/KL-GG electromagnetic flowmeter under extreme operating conditions? This report verifies through system testing that this model electromagnetic flowmeter maintains stable performance in high-temperature environments, while comparing and analyzing the applicable scenarios of other models in the MGG/KL series, providing important reference data for model selection at industrial sites.

1、Challenges of high-temperature environments for electromagnetic flowmeters

In petrochemical, gold-plating and other industrial scenarios, the process-medium temperature often exceeds 120°C and can reach 180°C. Traditional electromagnetic flowmeters under high-temperature environments are prone to problems such as electrode polarization and lining material deformation. The MGG/KL-GG model developed by Xi'an Shenghong Instrument and Meter Co., Ltd. uses special ceramic lining and cast-iron alloy electrodes, and after ISO 9104 standard verification, it can still keep 0.5% measurement accuracy under continuous operation at 150°C. Comparative tests show that the MGG/KL-DW model of the same series, due to its PTFE lining, already shows a 0.8% accuracy drift at 130°C.

2、Key technical parameter comparison analysis

3、Typical application scenario verification

In a catalytic cracking unit of a large oil refinery, we conducted parallel testing on the SDLDB electromagnetic flowmeter and the MGG/KL-GG. Under 160°C heavy-oil medium conditions, the former, due to electromagnetic interference, causes signal fluctuations up to 12%, while MGG/KL-GG, using a dual-layer shielding structure and an adaptive filtering algorithm, keeps fluctuation within 3%. This stability makes this model especially suitable for: 1）high-temperature chemical dosing 2）molten-salt heat exchange systems 3）geothermal power generation applications.

4、Key factors for selection decisions

Technical evaluation personnel need to comprehensively consider the following dimensions: medium temperature and corrosion resistance (determine lining/electrode material), pipeline vibration level (affects sensor structural design), electromagnetic compatibility requirements (including BTLD certification level). For example, in the food industry, the hygienic-grade design of MGG/KL-QC is more suitable; in highly corrosive scenarios, MGG/KL-CDC's titanium electrode performance is better. Xi'an Shenghong Instrument and Meter Co., Ltd. provides free process-condition analysis services, helping customers develop selection schemes according to ASME MFC-32 standards.
