| | | Switching range and switch point adjustment: Tne switch ranges refer to the limits within which the switch point may infinitely be adjusted. The actual flow throughput can, depending on the flow velocity, be much larger. The arrow marking the switch-off-point is positioned in line with the required flow rate, marked on the scale attached to the body. | | |
| | | |
| | | Switch hysteresis: Hysteresis is the difference in flow between the switch closing and opening again. By means of the careful choice of reed switches with particularly close differential, a typical hysteresis of 0.5 ...1.5 mm can be achieved with the BFS-series. | | |
| | | |
| | | ty compensation: | | |
| | | Viscosity compensation is achieved by the combination of the spring and the calibrated orifice inside the piston which guarantees high accuracy over a viscosity range of 1 to 600 cSt. | | |

| | | Maintenance instructions: | | |
| | | Due to the design, the flow monitor does not require any maintenance. The use of media containing magnetic particles requires cleaning intervals. These cleaning intervals can be prolonged by using filters with a magnetie separator. In case of vertical mounting with flow direction from top to bottom of the type BFS-10-N or BFS-10-0, the lowest switch points might fail to operate due to gravity causing a friction between bore and piston. | | |
