Apex Flow sensor 1/4 "with push-fit connectors suitable for osmosis tubes measures water flow in combination with the Apex system
This flow sensor is placed in the pipe for which you want to measure the flow speed. Connect the sensor to the FMM (not included). Is widely used with Osmosis devices and calcium reactors
The flow sensor itself uses push-fit connectors (standard 4 mm osmosis hose)
The FS-25 (1/4 "sensor) can measure flow rates of 11.3-45 liters per hour
