KROHNE Optisonic 8000 Ultrasonic Gas Flow Meter for Cryogenic & High Temperature Gases - [VN784]
The OPTISONIC 8300 is a 2-path ultrasonic flowmeter designed for the measurement of gases under extreme temperature conditions (-200°C…+593°C / -328°F…+1100°F) and at elevated pressures (up to 200 bar / 2900 psi). This makes it a standard solution for boiler and power plant monitoring or as a steam billing device. With connected temperature and pressure sensors, the flowmeter’s integrated flow computer can also calculate steam mass flow or enthalpy.
The OPTISONIC 8300 is equally well-suited for cryogenic gas applications, making it an ideal choice for boil-off gas (BOG) measurement or for flow measurement in air separation rectification (ASR) cold boxes.
The OPTISONIC 8300 was engineered to avoid costly downtime of steam pipes. It features a full bore flow sensor without moving parts or obstructions to prevent pressure drop. It can uphold its high measuring accuracy (<±1% of measured value) without maintenance or subsequent calibration for up to 20 years. There is no need to remove the meter, valves and a bypass are thus not required. If verification of the measuring accuracy is necessary, it can be provided using the flowmeter diagnostics. The OPTISONIC 8300 comes with digital communication options.
