This datasheet introduces the features and characteristics of the ABB FSM4000 Electromagnetic Flowmeter, including measurement range, accuracy, fluid type, working temperature, voltage, installation method, etc.
The ABB FSM4000 is an all-purpose electromagnetic flowmeter intended for measuring the flowrate of liquids, slurries, pastes, and sludges with a minimum electrical conductivity of 20 uS/cm. It features digital signal processing (DSP) to ensure long-term stability and accuracy in both forward and reverse flow directions.
| Minimum conductivity | at least 20 uS/cm |
|---|---|
| Accuracy (> DN 2) | < + 0.5% of rate |
| Fluid temperature range | -40 ... 130 °C |
| Meter size range | DN 1... DN 1000 |
The flowmeter can measure liquids with an electrical conductivity of at least 20 uS/cm.
Most installations require a straight inlet section 3 x DN long and a straight outlet section 2 x DN long.
The accuracy is less than + 0.5% of rate for sizes greater than DN 2.
