BAMO FFG flow sensor allows measurements of low flow rates for remote reading or totalization with appropriate monitors (refer to datasheet).
The dynamic pressure of the liquids makes rotate the turbine. The liquid passes through a calibrated nozzle, which increases its speed and that of the turbine. Magnets are integrated to the turbine and activate an Hall effect sensor inside the top cover. The electronic generates a pulsating signal, proportional to the speed of rotation of the turbine and therefore to the flow-rate.
Recommendations for assembly:
- The FFG works in any position, but it is recommended to mount it on a horizontal axis, with its upper body in a horizontal plane, to obtain reliable and precise measurements.
- Respect the straight pipe section of 150 mm upstream and 50 mm downstream in order to obtain a uniform flow.
- Installing an upstream filter prevents suspended particles from blocking the turbine (during commissioning, and, normal operation).
