The Krohne OPTISONIC 4400HT is a 2-path ultrasonic flowmeter for crudes, a broad range of refined products and other liquids that are processed at high temperatures. This makes the OPTISONIC 4400HT ideal for accurate flow measurement of high temperature feed flows in refineries. The OPTISONIC 4400HT is also suitable for the flow measurement of molten salt or synthetic heat transfer oil with high and rapidly changing temperatures at concentrated solar power (CSP) plants. Other typical applications include condensate as well as feed water or spray water measurement at power plants.
The dual path design of the OPTISONIC 4400HT compensates for variable flow profiles, maintaining unaltered measuring performance. Due to the rugged construction and its large dynamic design, the OPTISONIC 4400 boasts an excellent long-term stability and performs with minimum operational and maintenance costs. The OPTISONIC 4400HT comes as field-mounted version, and is available with a wide range of materials as well as sizes and can also be used in hazardous areas. Digital communication options and extensive diagnostics round off the functionality of the device.
