When selecting the explosion-proof type ultrasonic level meter, the following key factors need to be considered. The first is the measuring range, the measuring range of the equipment is 0-15 meters, which is suitable for the measurement needs of various container liquid levels. The second is the ambient temperature, explosion-proof type ultrasonic level meter can work normally in the harsh environment of -40 ° C to +60 ° C to ensure the reliability and stability of the equipment. The level of protection is also an important consideration, and the equipment complies with the explosion-proof class ExdIICT6, which is suitable for liquid level detection in flammable and explosive places. In addition, the output signal is another aspect that needs attention. Explosion-proof ultrasonic level meter provides two output modes of 4-20mA analog signal and RS485 digital signal, which is convenient for linkage control with other equipment. In terms of conversion mode, the device adopts a dual-channel conversion mode to achieve bidirectional transmission of measurement signals and repeated detection to ensure the accuracy and reliability of measurement. Precision requirements are also one of the factors that need to be considered when selecting, explosion-proof ultrasonic level meter has high-precision measurement capability, accuracy of ±0.5%, to meet the accurate measurement needs in the production process. Finally, the installation method, the equipment provides side installation, top installation and flange type three installation methods, you can choose the appropriate installation method according to the actual situation.
In addition to selection factors, the technical parameters of explosion-proof ultrasonic level meter also need to be understood. The operating voltage of the device can be selected AC220V or DC24V, the operating frequency is 20-100kHz, the response time is 1.5 seconds, and the signal delay time is 2.5 seconds. In terms of communication protocols, support Modbus and Hart protocols. Applicable media include liquid and solid. The system error is ±0.2%, and the anti-interference ability reaches 80dB.
Explosion-proof ultrasonic level meter is widely used in chemical, petrochemical, metallurgy, electric power, water treatment and other fields. It can be used for liquid level detection of storage tanks, reactors, pipelines, storage tanks and transformers. In the chemical industry, it can ensure the safe storage and transportation of various liquids; In the metallurgical industry, it can monitor the liquid level of chemical media and oil products; In the power industry, it can be used for transformer level monitoring; In the water treatment industry, it can be used for sewage treatment and level monitoring of source water supply. In addition, it is also suitable for liquid level monitoring and level monitoring in other industries.
