Specifications

Three functions: Flow switch, flow sight, and flow meter!

    • How to connect: M12 ×1-4 pin connector

    • You can use this with an input power supply of from 12 to 24 V DC.

    • Amplifier protection structure conforms to IP67 equivalent.

    • You can set a lower limit of flow rate. If flow rate falls below the limit, you are warned by a red LED lamp and an output signal.

    • In case of low pressure spec, you can check flow of fluid by observing rotor rotation from a metal/plastic cap.

    • In case of high pressure spec, you can measure flow rate at 25MPa.

      If you use DFS-2, 3, or 6, You must use an all-metal cap for high pressure. Factory setting: all-metal cap for high pressure.

    • You can select a position (horizontal, vertical, or tilted) to install.

    • Rotor can be cleaned by air blow, after taking off a metal cap from a main body.

    • Description

    The DFS-1-O has been discontinued. The DFS-8-O/W will be discontinued once the remaining stock of components is depleted.

    Body and overall spec

    ※1：You can't visually observe flow, when you use an all-metal cap.
    ※2：Guaranteed value at 32 cSt about O spec accuracy
    ※3：Ajustment depends on fluid which you use. Specify it when ordering.
    ※4：Indicated a value at 32 cSt, when max. flow rate.
    Amplifier spec

    ※5：You can select non-display mode.
    ※6：You can set a lower limit of flow rate optionally. Regarding how to set, refer to an instruction manual.

    Output type

    How to connect

    Principle

    The detection part of a digital flow sensor utilizes rotation of a 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.

    Accuracy

    The test at our factory is performed in the condition as follows.
    Confirm specifications of each digital flow sensor about accuracy.

    Precaution of use

    Example of use

    • Seizure can be avoided by oil flow control for the spindles and bearing of machine tools, printing machines, and presses.

    • Tool damage and fire can be prevented by control of coolant flow to machine tools.

    • This sensor is used to check if a filter is clogged or not.

    • Coolant flow control.
