ritical Technical Advantages
-
Real-Time Methane Analysis: Unlike standard flowmeters that only provide volume data, the B 200 calculates the methane fraction internally. It achieves this by combining sound velocity measurement with an integrated temperature sensor, enabling continuous energy balancing without the need for an external gas analyzer.
-
Optimized for Low Pressure: Biogas systems often operate at very low pressures, where traditional meters create unacceptable pressure drops. The B 200 features a full-bore design with no internal obstructions, ensuring zero pressure loss and preventing the buildup of moisture or contaminants.
-
Reliable in Wet Gas: The sensor design is specifically optimized for saturated gases. It remains accurate even when water droplets or condensate are present in the gas stream, which is a common occurrence in anaerobic digesters and landfill gas applications.
-
Loop-Powered (2-Wire) Technology: The B 200 uses 2-wire technology, allowing it to be integrated into existing systems using the same cabling for power and signal. This significantly reduces wiring costs and simplifies installation in large-scale biogas plants.
-
Heartbeat Technology: This integrated suite provides continuous diagnostic coverage and traceable verification of the device’s health. It allows for “in-situ” verification without interrupting the process, ensuring compliance with environmental regulations and safety standards.
-
Safe Interaction: The robust dual-compartment housing and touch-control display mean the device never needs to be opened in the field. This maintains the explosion-proof integrity of the unit during configuration or diagnostic checks in hazardous zones.
