Wet Parts Made of Non-metallic Materials andCompact Design
Flow Rate Monitoring of Various Liquids

W-1000MINI-WHEEL FLOWMETEROUTLINE
The W-1000 series is a rotary vane-type flowmeter developed byintegrating the technology of the W-200/300 series that has been
proven for many years, and, by using non-metallic wet parts, it
became possible for the W-1000 series to be used for various fluids.
There is a rotary vane containing magnets in the flow path, and thenumber of its rotations that are proportional to the flow rate arecounted in a non-contact manner using a magnetic sensor. The
W-1000 series, which is compact and easy to maintain, is optimalfor monitoring flow rates of various liquids.

FEATURES❏ Pulse, current, and voltage output❏ Minimum range: 0.3 to 1 L/min, Maximum range: 6 to 60 L/min❏ Visible wheel rotation❏ The model of its body made of resin is non-metallic for all wetparts❏ Customizable materials, structures, etc.
❏ Easy overhauling, cleaning, and maintenance❏ Complying with RoHS

NOTES❏ Do not run signal cables along with other power or motor cables.
❏ The inside diameter of process piping and fittings must be greater than the diameter of the flow path nozzle.
❏ Install this product in a location where it will not be affected by magnetic fields.
❏ When using the product, ensure that the main body is filled with water and that there is no air near the wheel.
❏ Do not use air blowers to blow the product. Otherwise, the wheel and/or shaft may be damaged.
❏ It is recommended that a straight section with a diameter of 10 D or larger (D: Inside diameter of the connected pipe) be provided in theupstream piping if an uneven or swirling flow is expected to occur.
