Critical Technical Advantages
-
Blockage-Free Gas Supply: Unlike rotary or turbine meters, the FLOWSIC500 has a completely open measuring channel. If the meter encounters debris or high-pressure surges, there are no mechanical parts to jam or break, ensuring the gas continues to flow to the customer without interruption.
-
FlowDC Technology (No Straight Runs): The meter is insensitive to flow disturbances. It can be installed directly after a 90° elbow or regulator without requiring long straight inlet or outlet piping zones, making it ideal for compact measuring stations where space is at a premium.
-
Intelligent Cartridge Exchange: The entire measurement technology is contained within a calibrated cartridge. When recalibration is required, the user can simply swap the cartridge in the field rather than removing the entire meter body from the pipe. This drastically reduces downtime and logistics costs.
-
Power Autonomy: The FLOWSIC500 can operate in a completely self-sufficient energy configuration using an internal battery for up to five years. Alternatively, it can be connected to a failsafe network with battery backup to ensure continuous measurement during power outages.
-
Integrated Flow Conversion: The meter can be equipped with an integrated volume corrector. This allows the device to convert measured volume at operating conditions to standard volume based on internal pressure and temperature data, providing a complete fiscal solution in one unit.
-
Intelligent Diagnostics: The system continuously monitors its own health. It can detect changes in gas quality or transducer performance and alert the operator before a failure occurs, moving maintenance from a reactive to a predictive model.

Primary Applications
-
Municipal Gas Distribution: Precise fiscal measurement at transfer stations between regional transport lines and city grids.
-
Industrial Gas Stations: Monitoring gas consumption in factories, boilers, and furnaces where high accuracy and low maintenance are required.
-
Commercial Metering: Billing-grade measurement for large commercial complexes and hospitals.
-
Station Retrofits: Easily replacing old mechanical meters due to the standardized face-to-face dimensions (compatible with turbine and rotary meters).
-
Dynamic Load Applications: Ideal for processes with frequent start/stop cycles or rapid flow changes that would damage mechanical meters.
