- Covers very low flow rates of 0.6 to 3 L/h
- 2-wire 4 to 20 mA DC output
- Magnetic field sensor detects the float movement with electronics to eliminate hysteresis. High accuracy and repeatability have been achieved
- Easy- to- read digital LED display
- No liquid dampers are needed even for gas measurement applications
- Ex d IIC T6 flame proof construction suitable even for Hydrogen atmosphere
