In precise flow monitoring in the chemical industry, the TC-GYDC electromagnetic flowmeter has become the preferred choice by virtue of its high stability. This article explains a 3-step selection method in detail for you, covering comparisons of TC-QSDC, TC-WSDC and other series models, helping you quickly match different operating condition requirements such as HYLD, ZA/ZB. With professional sensor technology, Xi'an Shenghongchuang Instrument Co., Ltd. provides reliable measurement solutions for the process industry.

I. The Core Value of Electromagnetic Flowmeters in the Chemical Industry

In the chemical production process, corrosive media and high-pressure, high-temperature environments place stringent requirements on flow measurement equipment. TC series electromagnetic flowmeters adopt a combination of special lining materials (such as polytetrafluoroethylene) and 316L electrodes, perfectly addressing the challenges of measuring strong acid and strong alkali media. Compared with traditional mechanical flowmeters, models such as TC-GYDC offer advantages such as no pressure loss and a wide turndown ratio (up to 1000:1), and in typical chemical scenarios such as aniline and chlor-alkali, the measurement error can be controlled within ±0.5%.

II. Detailed Explanation of the 3-Step Selection Method

Step 1: Match Medium Characteristics

Select the sensor type according to the medium conductivity (required >5μS/cm):

• TC-QSDC: suitable for ordinary conductive liquids such as industrial water
• TC-FFDC: specially designed for slurries containing solid particles
• TC-CDC: a specially optimized version for low-conductivity media (such as liquid CO₂)

The medium compatibility test report provided by Xi'an Shenghongchuang shows that its ZA/ZB series linings can still maintain a service life of more than 5 years in 98% concentrated sulfuric acid.

Step 2: Confirm Operating Condition Parameters

Step 3: Functional Expansion Requirements

The TC-DCZHQ intelligent type supports HART/Modbus communication protocols and can be seamlessly connected with DCS systems. For occasions requiring explosion-proof certification, the HYLD series has obtained both ATEX and IECEx certifications, meeting the usage requirements for Zone1 hazardous areas.

III. Analysis of Common Selection Misunderstandings

Misunderstanding 1: Blindly pursuing high accuracy
In actual operating conditions, factors such as vibration and bubbles will affect measurement results. The flow conditioner equipped as standard in the TC series can effectively eliminate such interference. According to the API MPMS standard, selecting Class 0.5 accuracy for chemical process control is fully sufficient.

Misunderstanding 2: Overlooking installation conditions
Electromagnetic flowmeters require a straight pipe run of 5D upstream and 3D downstream. In space-limited situations, the HQ series compact design can be selected (requiring only 3D upstream and 1D downstream). Xi'an Shenghongchuang provides free installation solution consulting services to help customers avoid measurement deviations caused by improper installation.

IV. Industry Application Case

A project of a large chlor-alkali enterprise:
By using 12 TC-GYDC electromagnetic flowmeters to replace the original vortex flowmeters, a 32% reduction in maintenance costs was achieved. Through a customized combination of PFA lining and tantalum electrodes, the difficult problem of wet chlorine gas measurement was successfully solved, saving about 2.8 million yuan annually in material losses caused by metering errors.
