KROHNE – OPTISONIC 7300 BIOGAS

The OPTISONIC 7300 Biogas is an ultrasonic flowmeter for low pressure biogas, landfill and sewage gas applications. The flowmeter is ideally suited to measure biogas with a high CO₂ content as well as small amounts of other media like H₂S, nitrogen, hydrocarbons or condensation water. Its corrosion resistant titanium transducers provide a strong ultrasonic signal into the gas. The signal processing of the meter allows a better detection of small, strongly dampened acoustic signals.

Features & Options

• Bi-directional flow measurement over a wide dynamic range
• Integrated temperature measurement
• Integrated calculation of standard volume with optional integrated pressure sensor
• Insensitive to corrosive components in the gas (e.g. H₂S)
• High accuracy: ±1% error of measured value (±2% of methane content)
  • User-friendly parameterisation, monitoring and on-site verification
  • Extensive sensor and process diagnostics
  • Via HART^® using the OPTICHECK DTM
  • Verification report about device status with one click
• With lap joint flanges for lower overall weight
• Full bore design: No moving parts, no wear, no pressure loss
• No periodical maintenance needed
• Available as remote version with field converter
• Also for use in hazardous areas zone 1
