Krohne OPTISONIC 4400 2-path ultrasonic flowmeter

Wednesday, 17 January, 2018 | Supplied by: KROHNE Australia Pty Ltd


The OPTISONIC 4400 is an inline 2-path ultrasonic flowmeter for flow measurement at elevated process temperature and pressure. It is available in two versions: high temperature (HT) and high pressure (HP).

With a full bore, unobstructed sensor tube and large dynamic range, both OPTISONIC 4400 versions feature high long-term stability and perform with minimum operational and maintenance costs. The dual parallel path design provides information about the flow profile and can also compensate for varying flow profiles. Wet calibration is standard for both versions. Options include redundant designs for safety applications with complete separation of electronics. In addition to 4–20 mA outputs, OPTISONIC 4400 flowmeters feature HART 7, Profibus PA and DP, Modbus RS485 and Foundation Fieldbus communication (NAMUR NE 107 compliant).

The OPTISONIC 4400 HT has an operating temperature range of -45 to 600°C and is aimed at flow applications such as molten salt or synthetic thermal oil/HTF in concentrated solar power plants (CSP), hot liquid hydrocarbons in oil refineries or feed water measurement in coal-fired thermal power plants. It features an accuracy of ±0.5% and ±5 mm/s in a measurement range of 0.5 to 20 m/s.

With a pressure range up to 490 bar, the OPTISONIC 4400 HP aims at high-pressure applications, such as water/chemical well injection or transportation networks in the oil and gas industry or for usage in petrochemical/refinery units or chemical plants. It features an accuracy of ±1% and ±10 mm/s.
