The biogas market is booming. No wonder, as the gas can be used in a variety of beneficial ways – including fueling vehicles or generating heat and electricity in combined heat and power plants.

The gas is obtained from

• Fermentation of energy

• Organic waste

• Liquid manure

• Sewage sludge

• Leftover plant materials

For biogas plants to work properly,various process parameters have to be monitored around the clock: gas composition, pressure, temperature, and above all the produced gas quan­tity. Prosonic Flow B 200 is an industry-optimized ultrasonic flowmeter that measures the volume flow of biogas, landfill or digester gas reliably and with high accuracy, even under greatly fluctuating operating conditions.

Ultrasonic measurement has numerous benefits compared to conventional methods:

• Reliable measurement – high accuracy (±1.5%) and a high operable flow range (30:1)

• Energy saving – no pressure losses

• Maintenance-free – no moving parts

• Space-saving – short inlet and outlet runs

• Wide range of uses – independent of the composition and the moisture of a gas

• Measurement possible even with minimum operating pressure

General Monitor's Model IR700 features a precision IR point sensing element that provides reliable protection against the hazards of carbon dioxide gas leaks. The IR700 offers a true fail-to-safe design for dependable gas detection performance, heated optics to eliminate condensation and a dirty optics indicator informs the user the device must be cleaned before the lenses are entirely blocked, thereby reducing downtime.

Carbon dioxide is an inexpensive and versatile gas that is useful in diverse applications from beverage carbonation to enhanced oil recovery techniques. While nonflammable and fairly innocuous, leaks can be dangerous. Exposure to atmospheric concentrations above 5,000 ppm is considered unhealthy, making careful monitoring crucial at lower levels. Atmospheric concentrations at 1% v/v (10,000 ppm) will make some people feel drowsy while concentrations of 7% v/v and higher can lead to symptoms including dizziness, headache, visual and hearing dysfunction, and unconsciousness.
