UTS Kobold Variable Area Flowmeter


The KOBOLD flowmeter model UTS works on the basis of the suspended float principle. It comes with a M18x1.5 connection. The inflow of the medium is via 4 mm hole within this connection, whereas the outflow happens via six holes which are concentrically positioned around the inlet hole. This special connection is specifically made for UTS and provided with a special seal.

This flowmeter can be optionally supplied with a special adapter G¼ or ¼" NPT for horizontal installation. The use of this adapter is always recommended because of its special design. Especially in tight places, where conventional devices do not fit best because of their size, the UTS is an automatic choice. The device is suitable for monitoring gas burners (e. g. oxygen, hydrogen, methane, inert gases e.g. MIG welding) due to its low price and possibility of an easy measuring tube exchange. The armature is made of nickel plated brass or stainless steel with impact resistant polystyrene protection
