Gas flow meters are essential tools for managing aerobic and anaerobic processes at wastewater treatment plants. Thermal mass type flow meters from Fox Thermal are the ideal solution for measuring gas flow rates, reducing costs, and meeting emissions requirements for greenhouse gases.Help Me Choose A Flow Meter
Thermal mass flow meters require no additional pressure or temperature compensation instrumentation and unlike PD or turban meters, they have no moving parts that can wear or bind so they require no maintenance.
Anaerobic wastewater digesters produce biogas mixtures that can change over time. To reprogram the percentages of component gases in your flow meter and avoid sending it back to the factory for recalibration, you need a more flexible solution.
Compared to DP meters, Fox Thermal mass flow meters provide a large turndown rate, with a repeatability of up to 1,000:1 (typically 100:1) for very high velocity or for very low flow rates, which are common in anaerobic digesters.
Properly managed, wastewater treatment reduces risks to the environment and public health caused by pathogens, toxic chemicals, antibiotics, and excess nutrients.
Gas flow measurements of compressed air in aerobic wastewater treatment can improve efficiency. For the anaerobic digestion of organic particles in wastewater, flow measurements can help keep track of biogas emissions. When biogas is used for heat or power generation, flow meters ensure accurate measurement of the fuel gas produced.
All of these operations in wastewater treatment plants require accurate measurement of gases flowing through the system.Learn More
An electromagnetic flow meter is not an option for measuring the flow of gases in wastewater applications, due to their low conductivity. Ultrasonic flow meters and Coriolis mass flow meters can be used, but these come at a higher cost than thermal mass flow meters.
The best flow meter technology for wastewater treatment facilities is thermal mass flow meters, which offer a low-cost, high-accuracy option with a wide turndown ratio.
For example, the Fox Thermal model FT4X thermal mass flow meter comes equipped with the state-of-the-art DDC-Sensor™ technology, new expanded Gas-SelectX® gas selection menu, CAL-V™ Calibration Validation, AC input power option, and a standard data logger with date and time stamp, for accurate emissions reporting.
