Under the harsh operating conditions of the petroleum industry, HKE electromagnetic flowmeters have become the first choice of technical evaluators thanks to their outstanding stability and accuracy. As a core product of Xi'an Shenghongchuang Instrument Co., Ltd., the HKE series, together with professional equipment such as TOP-101 electromagnetic flowmeters and RXLDB electromagnetic flowmeters, jointly solves the measurement challenges of high-viscosity media and provides reliable data support for petrochemical process control.

I. Core Challenges of Flow Measurement in the Petroleum Industry

The petroleum industry has extremely stringent requirements for flow measurement equipment, mainly reflected in three aspects: first, petroleum media usually have high viscosity and strong corrosiveness, and ordinary flowmeters are prone to blockage or electrode corrosion; second, oil pipelines experience large pressure fluctuations (often reaching 6.3MPa or above), requiring equipment to have extremely strong pressure resistance; third, oilfield extraction environments often involve strong electromagnetic interference, requiring flowmeters to have excellent EMC performance. Xi'an Shenghongchuang's HKE electromagnetic flowmeters use special lining materials (such as PTFE/PFA) combined with 316L electrodes, together with an IP68 protection rating design, to perfectly cope with these challenges, and their measurement accuracy can reach ±0.5%R, far exceeding the requirements of the ISO 9104 standard.

II. Analysis of Key Technical Performance of the HKE Series

Compared with common 93636-135 electromagnetic flowmeters or 93454-543 electromagnetic flowmeters on the market, the HKE series achieves technological breakthroughs in three aspects: 1) adopting multi-frequency excitation technology to effectively suppress slurry noise, especially suitable for crude oil measurement with a solid content of up to 30%; 2) a built-in temperature compensation module that still maintains ±0.2% temperature drift control under operating conditions of -30℃~180℃; 3) a modular design supporting dual HART/Modbus protocols for seamless integration with DCS systems. Specific parameter comparisons are shown in the table below:

III. Typical Application Scenarios and Customer Cases

In the crude oil transportation project of Changqing Oilfield, the HKTMF electromagnetic flowmeter successfully replaced traditional mechanical flowmeters and achieved three key improvements: 1) reducing the measurement error of water cut from ±5% to ±1.2%; 2) extending the maintenance cycle from 3 months to 12 months through a self-cleaning electrode design; 3) achieving an explosion-proof rating of Ex dⅡCT6, meeting the API RP 500 standard. Similarly, at the Nanhai Petrochemical refining base, 20 HKE-150 models and JY-LDE electromagnetic flowmeters formed a redundant measurement system, operating continuously for three years without failure and helping the customer pass SIL2 safety certification.

IV. Key Technical Evaluation Points for Procurement and Selection

When selecting 93718-353 electromagnetic flowmeters, technical evaluators need to focus on: 1) whether the medium conductivity is >5μS/cm (the HKE series can measure as low as 1μS/cm); 2) whether the pipeline vibration frequency is within the range of 10-1000Hz (it is necessary to select the damping adjustment function); 3) whether intrinsic safety explosion-proof certification is required (HKE provides dual certification options of ATEX and IECEx). Xi'an Shenghongchuang's engineering team recommends that for extreme operating conditions where TOP-101-25 electromagnetic flowmeters cannot meet requirements, customized HKE solutions can be adopted, such as installing a magnetic flux compensator or using a remote split structure.
