>>Dinghua G80 spring trial has begun. Nitrotoluene: yellow orthorhombic crystals; toxic and flammable; density 1.392 g/cm3, melting point 51.7°C; insoluble in water, but soluble in ethanol, ether, chloroform, and benzene. It is mainly used in the production of DSD acid, p-*-formic acid, p-*-acetic acid, etc., and is also frequently used as an intermediate for dyes as well as for agrochemicals, pharmaceuticals, plastics, and synthetic fiber additives. The case in this issue comes from a tank for p-nitrotoluene at a chemical plant in Hubei; it is a vertical storage tank with a height of 7 meters, and the medium stored inside it is a p-nitrotoluene solution. Since the tank went into operation, imported radar level gauges have been used for level measurement. ►►►Measurement challenges: Due to the severe crystallization of p-nitrotoluene, conventional radars often encounter problems such as crystallization on the inner surface of the radar antenna during measurement, which leads to signal loss in the radar. The company had previously used imported 26G pulse radar level gauges; after installation and operation, users were required to disassemble the radar themselves on a monthly basis to clean off crystals, which was time-consuming and labor-intensive. Moreover, for a major hazard source such as a nitrotoluene tank, a failure of the level gauge can very likely lead to serious consequences. ►►►After understanding the user’s usage patterns, Dinghua recommends the Dinghua G80 frequency-modulated radar level gauge based on the specific conditions at the site. https://nwzimg.wezhan.cn/contents/sitefiles2057/10285453/images/39880553.png Model: DHE-RD-5100-8IMC1FCH2MA Range: 0–7 m, Accuracy: ±1 mm, Operating temperature: -40–130°C. Supports Hart bus protocol for output. 1. The Dinghua G80 frequency-modulated radar level gauge features an antenna with a 3° beam angle, which significantly improves its resistance to interference; this enables more stable and reliable echo signals, effectively reducing the impact of medium crystallization. Furthermore, Dinghua’s unique “ELL signal analysis technology” helps reduce the impact of various false echoes, ensuring high reliability of the radar during operation. 2. The radar is easy to install on-site and simple to operate. It comes equipped with fault alarm and self-diagnosis functions, allowing users to conduct fault analysis and troubleshooting promptly based on the codes displayed by the operation display module, thereby enabling more accurate and efficient maintenance and calibration. 3. Since its installation and operation, the radar has provided accurate level measurement, and the DCS trend displays in the remote control room are precise, fully meeting the requirements for high precision and high reliability in production.
