THE NEW WY FLOW MONITOR & INDICATOR

The New Flow-Monitor Type WY with Inclined Position

The most obvious feature of the WY is its innovative design. The float is mounted at an angle to the body. This results in a variety of advantages. The WY is a flow monitor and indicator for liquid media and designed for measuring ranges of 2.5 – 25 l/min (WY-15) and 10 – 100 l/min (WY-25) as well as media temperatures up to 100 °C.

Advantages of the WY-Design

Typical Applications of the WY:

Where ever reliable supply of liquid media is important even at high temperatures and confined space conditions the WY is the solution of choice.



The WY Combines Many Advantages
in Confined Space Conditions

Compact design & large measuring range

Variable area flowmeters generally have a measuring range of 1:10 (e.g. 10 – 100 l/min). Very compact instruments on the other hand, have smaller ranges, for example 1:3. The WY flowmeter combines a compact design with the large measuring range of standard flowmeters. Wherever space is at a premium, the WY is the first choice.

Easy to maintain & clean

The Y-shaped design allows all internal parts of the WY to be removed without removing the device from the pipe system. This reduces the effort for cleaning and/or maintenance significantly.

Variable Positioning

Float flowmeters must normally be installed vertically. Thanks to a spring that always returns the float to its initial position, the WY allows the installation in almost any position.

Direct Display Reading

The burned in scale on the sight glass allows the current flow to be read directly on the device. The borosilicate glass (DURAN® 50) used is highly chemical and temperature resistant. Optionally, colored LEDs can be used to display the switching status.

Free flow

The float is deflected into the inclined position. This clears the flow cross-section and minimizes the pressure loss.

Easy Switching Points Setting

The operator can precisely set the switching points for the flow limit values directly on the device. For this purpose, the switching contact is simply shifted to the desired flow value. The adjusted value can then be read from the switching point scale attached to the side of the device housing. The switching contact is located on the outside of the device and is not in direct contact with the medium.

The float is deflected into the inclined position. This clears the flow cross-section and minimizes the pressure drop.

The current flow can be read directly on the device via a burned in scale on the sight glass.
