Application of Flap-11 Magnetic Level Indicator in TDI Liquid Level Measurement Toluene diisocyanate (TDI) is an organic compound. All isomers of TDI are colorless or yellowish with pungent odor. It is volatile and hypertoxic. TDI is an important part of polyurethane raw materials, which is widely used in light industry, chemical industry, electronics, textile, medical, construction, building materials, automobile and other fields. The synthesis process of sponge in Shantou Sponge Factory mainly includes chain growth reaction, foaming and cross-linking. The main source of foaming gas CO₂ gas generated by the reaction of TDI with water, so a large amount of TDI is used as raw material in the factory. Because TDI is hypertoxic, it is necessary to prevent it from overflowing as well as empty running, so timely monitor and control the liquid level is significant. Jiwei Flap-11 Magnetic Level Indicator From communication with clients, we know that the operational condition is complex: 1. The narrow spaces between storage tanks are easy to bump and damage the equipment. 2. High humidity affects instruments with low Ingress Protection Level. 3. Strong vibration and stirring in the tanks. 4. Tall tanks need remote/distant observation. 5. Explosion-proof instruments are required, cause TDI is inflammable, explosive and toxic. The client used sight glass to measure the liquid level of TDI storage tanks. However, glasses become compromised through leaking seals, clouding, and breakage, as well as unable to realize automatic control. So, the client finally selected Jiwei Magnetic Level Indicator after detail discussion. Jiwei Magnetic Level Indicator devices are popular in applications measuring Shenzhen Jiwei Automations Ltd.

high-temperature, high-pressure, and corrosive liquids. When the application is challenging, magnetic level transmitters (remote transmitters) provide consistent, accurate measurements. Magnetic level indicators are commonly low-cost in comparison with other level technologies, and can provide visual indication of TDI level from a distance.
