UFC 400

Ultrasonic flow converter for combination with OPTISONIC 3000 and OPTISONIC 4000 flow sensors

  • Compact or remote field housing
  • With extensive diagnostics (NAMUR NE107) for advanced requirements
  • 4-wire, 3 x 4…20 mA, HART®7, FF, Profibus-PA/DP, Modbus etc.

Overview

The UFC 400 is a 4-wire ultrasonic signal converter. Combined with the flow sensors OPTISONIC 3000 and OPTISONIC 3000 District Heating it forms the OPTISONIC 3400 ultrasonic flowmeter for inline flow measurement of liquids as well as the OPTISONIC 3400 District Heating ultrasonic flowmeter for use in heat metering applications. Together with the OPTISONIC 4000 HT and HP flow sensors it forms the ultrasonic flowmeters OPTISONIC 4400 HT and OPTISONIC 4400 HP  for inline flow measurement of high temperature and high pressure liquids.
