Problem
Starch products are produced from corn processing. The process effluent waste water produces Biogas as a by-product with the help of the fermentation process. Biogas produces waste-gas (Biogas flow measurement) used for heating boilers and generators for energy conservation.
- Biogas is generated at very low static pressure approx. 800mmwc to 1200 mmwc.
- Biogas generate with low velocity & contains high moisture content ( 3%-5%Vol)
- Existing orifice/ vortex flow meter doesn’t work at low flow rates.
- Existing orifice / vortex flowmeter creates high pressure drop so have to increase pressure by the blower system with additional investment
Solution
Leomi – 586 Insertion Thermal Mass flowmeter
- High turndown down ratio of 100:1 against 4:1 of existing installation.
- No pressure drop against the existing flow meter can be installed after the gas holder, saving energy cost by removing the blower system.
- High accuracy against orifice/ vortex flowmeter
- Works well even in high moisture content
- Doesn’t require shutdown for installation
- No maintenance than the existing flow meter used.
