This version ensures a functional flow check from two points of view. On one hand, its construction as a visible cylinder gives a relatively large and thus easily observed field of observation; in addition, the rotary movement of Teflon rotor permits reliable monitoring of cloudy or dark media due to its noticeably bright colour. This type of device is already widely used and has proved itself in industrial use thanks to its functional reliability. 

The unique design and construction of the DAA flow indicator, specifically the incorporation of two wiper elements have resulted in a product first - combining a flow indicator with a device that allows the equipment to be cleaned during operation. The sight tube is rotated so that the wiper elements concentrate the dirt into two narrow strips on the interior of the glass. From there it is taken away effortlessly by the flow.

The Borosilicate glass tube is fitted with O-rings which slide easily so that the cleaning of the unit can be carried out by hand even under full operating pressure. The flow indicator with an integral cleaning device can be used in any position for checking the flow of gases and liquids. A choice of sizes is offered and flow rates of 0.4 l/min up to 100 l/min H2O can be reliably checked. Along with the standard housing version in brass, the units are also offered in a resistant stainless-steel version for aggressive media. If the rotor is unwanted for particular applications, for example increases in flow rate, the unit is also available with just a sight glass with a cleaning device.
