Critical Technical Advantages
-
Optimized for Harsh Emissions: The system utilizes rugged titanium transducers as standard, providing exceptional resistance to corrosion and mechanical wear. This ensures a long service life even when exposed to the abrasive and chemically aggressive gases found in cement or chemical plants.
-
Versatile Installation Variants: The FLOWSIC100 offers diverse configurations to match specific duct geometries. The H, M, and S types perform cross-duct measurement for maximum accuracy in large stacks, while the PR probe version allows for single-sided installation, significantly reducing installation costs and efforts.
-
High-Temperature Capability: The AC (Air Cooled) versions feature an innovative internal cooling system, allowing the sensors to operate in gas streams up to 450 °C. For standard applications up to 260 °C, the device operates reliably without any purge air requirement.
-
Contamination Resistance: For processes involving sticky or wet dust, the purged Px versions use a continuous air flow to keep the sensor faces clean, preventing signal degradation and minimizing maintenance intervals.
-
Automated Operational Checks: The device performs automated zero and reference point tests. This self-monitoring capability ensures high data availability and compliance with environmental regulations by providing documented proof of measurement stability.
-
No Process Interference: The ultrasonic measurement is non-intrusive and creates zero pressure loss. This means the meter does not affect the process draft or increase the energy consumption of the plant’s fan systems.
-
SOPAS ET Software Integration: Users can easily configure, monitor, and diagnose the system using the user-friendly SOPAS ET software, which provides deep insights into the device’s diagnostic health and signal quality.
