Reliable, maintenance-free flow measurement with new hi-tech transmitter.
ABB’s robust swirl flow meters are designed for reliable measurement of liquid, gas and steam in volume, mass or energy units.
- Digital signal processing for volume flow, totalisation and pulse outputs leads to high reliability and flexibility
- Direct mass/energy flow or standard flow measurement without additional flow computer
- Hot pluggable display unit with through the glass (TTG) operation
- Integrated 4…20 mA and HART 7 interface for pressure, gas content, temperature or medium density input
- Latest hazardous approvals incl. Zone 0 / Zone 20 approvals
- Low upstream and downstream requirements enable flexible installation without use of a flow straightener.
Intuitive operation:
- “Easy Set-up” even without manual
- 4 button operation, optionally through the glass with closed cover
- Well proven menu structure, common philosophy with other ABB instruments
- Sensor memory allows the exchange of electronics without recalibration or manual setup
- Meter diagnostics with clear help texts in the display
- Auto-Zero function for noisy applications
Lowest up and downstream requirements enable many applications
Immune to turbulence, allows installation:
- Without additional flow straightener
- Without pipe reduction
- Within 3D upstream/1D downstream down to no upstream/downstream
- Within 5 diameters behind from upstream control valve
Broad range of uses due to advanced electronics
Highly advanced electronics providing:
- Integral vibration cancellation
- Wide flow range up to 50:1 flow turn down
- Highest accuracy in liquid, gas and steam measurement
- Shortest response time (200ms)
- Enhanced diagnostic functions for sensor supervision and temperature monitoring
- Special operation modes for steam energy flow with or without condensate backflow
- Gas engine for natural gas measurement according to AGA/GERG standards
