Project Requirements

The measured medium is hydrochloric acid (the concentration range is uncertain) ,Customers need to measure the cumulative flow data of hydrochloric acid flowing through the pipeline by electromagnetic flowmeter.

Selection Recommendations

The tested medium is hydrochloric acid. Based on the corrosive characteristics of the  medium, ARTang engineers selected the PTFE liner, Hastelloy B electrodes for the customer. However, based on the previous project experience in chemical industry, the concentration of hydrochloric acid in the measured pipe may change. HB electrodes can test the hydrochloric acid medium with low concentration . However, if the concentration of hydrochloric acid thickens later, the output of the converter may jump . Therefore, based on the complex chemical changes of the tested piping, we recommended customers to choose tantalum electrodes with better  and stable performance in more corrosive mediums.In addition, considering the working conditions of the chemical plant, and magnetic flow meter with explosion-proof design was provided to our customers ,to guarantee the safe operation in chemical plant.

Customer Feedbacks

The electromagnetic flowmeter is corrosion resistant and uses explosive insulation design (Exd) to ensure the safety requirements of operation under high-temperature and high-pressure conditions in the chemical industry. The engineer is experienced in the project and understands the process process of the chemical industry.Selection recommendation is  professional; technical specification and user manual are clear and detailed, the whole installation process was very easy and time-saving when we used those files and saw the related instrument operation video.

盐酸测量时选型

Note: A - Applicable; B - Usable, but life is short; N - Unavailable; X - Corrosion Resistant, but not recommended; Blank - No Data ; R-room temperature; S-boiling point; Sat-saturation; (M) - determined by maximum temperature that  Lining can resist.

This list is selected from a variety of sources, and the "applicable" or "not applicable" material is only an overview,  Those which do not list concentrations and temperature ranges do not mean that they are "applicable" to any concentration and temperature range.

The mixing ratio, concentration and temperature of liquids have a great influence on the corrosion resistance of materials, and other factors such as trace impurities and dissolved gases and flow velocity also influence the corrosion resistance of materials. The user shall conduct investigation according to the actual conditions of use. If necessary, the field medium may be used to carry out laboratory corrosion resistance tests on the first selected materials. It is preferable for the field slab to be used as the closest test to the actual conditions of use.

This list serves only as a reference for the preliminary election, and the reference to "applicable" in the material should not be interpreted as "recommended" and its application should ultimately be determined by the user.
