Magnetic Level Indicator Applied in Concentrated Hydrochloric Acid Liquid Level Measurement Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula HCl. Hydrochloric acid has a distinctive pungent smell. Concentrated hydrochloric acid colorless to yellowish pungent liquid. It is highly corrosive but noncombustible. Soluble in water, alcohol, and benzene. Chongqing Jianshe Automobile Air Conditioner Co., Ltd. is a manufacturer with an annual output of 80 thousand air conditioning compressors. In the concentrated hydrochloric acid (36-38.0%) auxiliary material tank. Hydrochloric acid is corrosive, and concentrated forms release acidic mists that are also dangerous. If the acid or mist come into contact with the skin, eyes, or internal organs, the damage can be irreversible or even fatal in severe cases, so it is usually packed in closed opaque containers or tanks. To avoid accidents caused by hydrochloric acid overflow, it is necessary to monitor the liquid level in real time with reliable liquid level measuring instrument. Shenzhen Jiwei Automations Ltd.

Liquid level instruments commonly used in the market include float level indicator, ultrasonic level transmitter, radar level meter, magnetic level indicator, etc. Base on the strong corrosive characteristics of concentrated HCl, the advantages and disadvantages of the instruments are compared as the following table: Strong corrosive application effect, as the float Float level moves, Float and guide tube are coated with acid and alkali resistance, so the cost Contact increases and the price also rises float level indicator are magnified. Reflected wave is Ultrasonic Only suitable for open...

concentrated HCl level control. The client has tried most above instruments except magnetic level indicator, with high cost but dissatisfied result due to the strong corrosivity and volatility of concentrated HCl. After contact with Jiwei, the client had a detail communication with the engineer. At first, Jiwei engineer recommended Flap-11Px Lined Magnetic Level Indicator, which is suitable for most strong corrosive liquid medium and the chamber is made of 304 stainless steel lined with F4 (PTFE)/F46 (FEP) for strong corrosive liquid level measurement. However, the concentrated HCl storage...

Accessory magnetic switches and remote transmitters have been explosion protection certified for both Flameproof Enclosure and Intrinsically Safety. From the feedback, all Flap-11C Plastic Magnetic Level Indicators have been running stably and reliably without any problems. The outstanding performance of Flap-11C in the level measurement of concentrated hydrochloric acid is beyond the client’s expectation, so he planned to purchase another batch for the next project.
