OPTISONIC 7300

Ultrasonic flowmeter for natural gas, process gas and utility gas applications

  • 2-path meter, for standard volume flow metering, independent of media properties
  • No maintenance, no pressure loss, large dynamic range
  • Flange: DN50…1000 / 2…40″, max. PN450 / ASME Cl 2500; also weld-in connections
  • 3 x 4…20 mA, HART®, Modbus, FF

The OPTISONIC 7300 is a universal 2-path ultrasonic gas flowmeter for process and utility gas measurements in oil and gas refineries or the chemical or petrochemical industries. It is also suitable for non-custody transfer natural gas applications or applications with (compressed) air, mixed or flue gases (up to +180°C / +356°F). Using the transit time differential measuring principle, the OPTISONIC 7300 delivers high performance over a wide flow range (up to DN600 / 24″, turndown ratio: 100:1). Its patented titanium transducers are perfectly focused, equalizing process fluctuations and avoiding acoustic feedback.
