Is the Krohne 7300 ultrasonic flowmeter from Cologne, Germany easy to use? The Krohne OPTISONIC 7300 ultrasonic flowmeter from Cologne, Germany performs well in natural gas, process gas, and utility gas applications, especially suitable for standard volume flowmeters. This device is not affected by the characteristics of the medium, does not require maintenance, has no pressure loss, and has a large dynamic range. Its flange connection covers a wide range, from DN50 to 1000, and also has 2 to 40 "options. The maximum pressure can reach PN450/ASME Cl 2500, or welding connection can be used. Equipment equipped with 3 channels of 4... 20mA, HART, Modbus, FF ® Interface to meet various communication needs. As a universal 2-path ultrasonic gas flowmeter, the OPTISONIC 7300 is suitable for process and utility gas measurement in oil and gas refineries, chemical or petrochemical industries, as well as for non metering natural gas applications or various applications of compressed air, mixed or flue gas (up to+180 ° C/+356 ° F). The device adopts the principle of transmission time difference measurement, which can provide high performance in a wide flow range (up to DN600/24 ", with a range ratio of up to 100:1). By using titanium transducers for focusing, the equipment can balance process fluctuations and avoid acoustic feedback, ensuring measurement accuracy. The measured volumetric flow rate can always be calculated to standard conditions using inputs from temperature and pressure sensors, which are directly connected to the device. After initial calibration, the equipment provides accurate measurement results (± 1% error of measurement values). Compared with turbines or other conventional gas flow meters, the OPTISONIC 7300 has no limitations on regular recalibration, maintenance, or pressure loss, demonstrating its superior practicality and reliability. In summary, the Krohne OPTISONIC 7300 ultrasonic flowmeter has been widely recognized for its high performance, stability, flexibility, and reliability in natural gas, process gas, and utility gas applications, making it an ideal choice in many industries.
