OPTISONIC 4400 HT

Ultrasonic flowmeter for high temperature liquids

  • 2-path meter for flow measurement of thermal oil, boiler feed water, crudes and hot feed flows in refineries
  • Up to +600°C / +1112°F
  • Flange: max. DN1000 / 40″
  • 3 x 4…20 mA, HART®7, Modbus, FF, Profibus-PA/DP

The OPTISONIC 4400 HT 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 flowmeter the perfect choice for accurate flow measurement of high temperature feed flows in refineries. It is also highly suitable for 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.
