Whenever flow of gases or liquids need to be adjusted or monitored, the KOBOLD variable area flowmeters model UTS are a practical and affordable solution. These very compact measuring instruments can be placed precisely at locations, where they are exactly required.
In the vertically installed flowmeters, the medium flows upwards in the inner borosilicate glass measuring tube and again downwards between the measuring tube and the outer piston made of transparent plastic. Float in the measuring tube provides information on the current flow, which is read on the scale clearly visible on it. Inlet and outlets are both located at the bottom of the instrument and may easily be accessed via optional adaptor with G ¼ thread on both sides.
Measuring ranges for gases range from 0.01... 0.1 Nm3/h to 0.3 ... 3.0 Nm3/h of air. 4 measuring ranges for liquids range from 1 ... 10 l / h up to 4 ... 40 l / h of water. Float and the O-ring seal are available in different materials, so that the best-suited type can be selected for a wide range of applications. Typical examples include monitoring supply to gas burners or engines and the supply of laboratory equipment with different gases. A version with upstream needle valve will soon be available to expand the application range.
