Endress+Hauser FLOWSIC500

Ultrasonic flowmeter

FLOWSIC500 is an ultrasonic gas flow meter with custody transfer capability for natural gas distribution. It provides accurate, reliable, and consistent measurements thanks to its no-moving-parts design, modular construction, and intelligent diagnostics. 

It can operate autonomously (on battery power) or as part of a secure network, with backup power support. The device is also designed to allow the measuring module (cartridge) to be replaced during verification without completely replacing the instrument.

The sensor's advantages include low operating costs, reliability under dynamic loads, ease of integration into existing stations, and simplified verification through cartridge replacement.

Measured variables:

• Gas volume at operating pressure
• volume flow rate
• gas velocity
• volume at standard conditions with integrated pressure/temperature correction

Flowsic 500 Datasheet:

• Measuring medium: Natural gas (dry, odorless)
• Nominal diameters: DN 50 (2″) … DN 150 (6″)
• Temperature: –40°C … +85°C (standard version)
• Pressure: Up to ~16 bar (depending on version)
• Basic operation (battery) or mains powered with battery backup
• Compliance with gas metering standards (custody transfer)

Flow meter design advantages:

• no moving parts (minimum wear)
• overload resistance
• integrated diagnostics
• modular cartridge replacement
• no straight pipe sections required upstream of the sensor
