Example of use
- Seizure can be avoided by flow control of lubricating oil for the spindles and bearings of machine tools, printing machines, presses and speed reducers.
- Tool damage and fire can be prevented by control of coolant flow to machine tools.
- This sensor is used to check if the filter is clogged or not.
- Coolant flow control.

| ※1： | You can not see fluid if the bl cap (for high pressure) is installed. |
| ※2： | We adjust each type of sensors at our factory in accordance with fluid type. Please specify the type of fluid you intend to use the sensor with when you place your order. |
| ※3： | Value for Max. Flow rate at viscosity 32 cSt. |
| ※4： | You can select the non-display mode. |
| ※5： | You can configure alarm flow rate optionally. See the DFS instruction manual on how to configure. |
| ※6： | We also sell a single article of sensor cable. Please ask us, for details. |
Principle of actuation
The detection part of digital flow sensor utilizes rotation of the rotor (turbine) installed in the passage. The measuring part detects, by means of the external magnetic sensor, the rotational speed of the permanent magnet mounted on the circumference of the rotor
You can select NPN output or PNP output optionally.
