Introduction

In the field of flow monitoring in the chemical industry, WST electromagnetic flowmeters are rapidly replacing traditional mechanical flowmeters. Measured data show that using electromagnetic flowmeter series such as ZFG-S/TOSHIBA-LF can reduce energy consumption by 30%, and their insertion-type PTFE lining design offers better corrosion resistance. This article will analyze how the LY-LDE series electromagnetic flowmeters achieve precise measurement through a structure without flow-blocking components, helping operators improve energy efficiency management.

Technical Comparison Between Electromagnetic Flowmeters and Traditional Flowmeters

Traditional mechanical flowmeters such as turbine and orifice types have problems such as high pressure loss, easy wear, and high maintenance costs. Taking actual measurements from a chemical plant as an example, after using the LY-LDE-A electromagnetic flowmeter, the annual maintenance cost was reduced by 45% due to its design with no moving parts. Based on Faraday's law of electromagnetic induction, electromagnetic flowmeters can achieve a measurement accuracy of ±0.5% for conductive liquids (such as acids, alkalis, and wastewater), far exceeding the ±2% of traditional instruments. The WSTE series from Xi'an Shenghongchuang Instrument Co., Ltd. also uses special lining materials, with a pressure rating up to PN16, suitable for extreme working conditions from -40℃~180℃.

Analysis of Chemical Industry Application Scenarios

In the transportation of highly corrosive media, the rubber-lined version of the ORBLDBE electromagnetic flowmeter can withstand up to 98% concentrated sulfuric acid, while the PTFE-lined AMF model is suitable for special media such as hydrofluoric acid. After a chlor-alkali enterprise adopted the insertion-type installed TOSHIBA-LF sensor, it not only solved the problem of reading drift caused by pipeline vibration, but also reduced pumping energy consumption by 17% thanks to the straight-through design of the DN300 diameter. The engineering team at Xi'an Shenghongchuang recommends that for slurries containing solid particles, priority should be given to the LDCR series models equipped with electrode self-cleaning function.

Typical Troubleshooting Guide

• Empty Pipe Alarm: Check whether the grounding ring of the LY-LDE electromagnetic flowmeter is corroded
• Signal Fluctuation: Confirm that the installation position of the WST flowmeter is more than 5 pipe diameters away from the pump valve
• Zero Drift: Perform electrode polarization calibration on the LY-LDE-A model

Core Factors in Procurement and Selection

When selecting an electromagnetic flowmeter, key considerations should include: medium conductivity (must be >5μS/cm), pipeline vibration level (recommended <2.8mm/s), and explosion-proof requirements (such as ATEX certification required in chemical areas). The WST electromagnetic flowmeter liquid flow sensors provided by Xi'an Shenghongchuang have all passed ISO9001 and SIL2 certification, and their split-type design allows the converter to be installed in a safe area. For the food and pharmaceutical industries, the hygienic clamp connection structure of the LY-LDE-B model can meet 3A standards.
