The flow transmitter model series DR20 work acc. to the paddle wheel principle. The medium flows unilaterally against the paddle wheel and puts it into rotation. This leads to a low response sensitivity combined with a high turndown ratio up to 1:20. The devices are in the version with a T-fitting for nominal sizes of DN 15 until DN 50 available. Therefore measuring ranges of initially 2,5 l/min up to 580 l/min can be covered.
In principle a weld on version can be used for many different pipe diameters. The analogue output is proportional to the flow rate and covers the range 0,3 until 5 m/s.
Typical applications
The paddle wheel flowmeter of the type series DR20 can be used for flow measuring of all low viscous liquids that are not aggressive to the used materials.
Because of the high quality bearings the devices work very reliably.
