To check the flow processes in pipeline systems and for insight into the interior of process pipes, many flow indicators are used in which the flowing medium sets a rotor turning and thus to a large extent visibly signals a flow. Instrotech is offering Kobold’s DAA self-cleaning flow indicator, with the unique characteristic of the rotor being housed in a rotatable glass cylinder. 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 has resulted in a product first – combining a flow indicator with a device which 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 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 cleaning device.

Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.
