Terms & Conditions
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.
The OPTISONIC 7300 Biogas features an integrated temperature sensor and optional pressure sensor that enables a temperature and pressure compensated standard volume calculation. The biogas meter also allows accurate online measurement of methane content in biogas and sewage gas (just ±2% error of measured value). This saves on costs as additional analytical systems for methane measurement are not needed. The biogas meter provides a wide measuring range (turndown ratio: 100:1). The OPTISONIC 7300 Biogas comes with ATEX approval (zone 1) and digital communication options.
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)
- 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
Typical applications
Renewable energy industry, wastewater industry
- Measurement of raw and wet biogas right after production/fermentation
- Methane measurement at the inlet of CHP (combined heat and power) systems
