UFJ Flow Indicator

Brand: KOBOLD Instruments, Inc.

The flow indicator model UFJ for liquids and gases operates on the suspended float principle; i.e. the installation position is vertical and the direction of flow is from bottom to top.

The instrument consists of a measuring tube in which a section around the set value is cut out. It has a marking in its slot comprising of a set value / switching point and ranging from approximately -1% to+5%, whereby the float indicates the presence of flow.

The apparatus is configured in such a way that when the flow is less than approximately -1% of the set value, only the float head is visible through the slot. When the flow is around the set value or greater, the float appears in the sight glass.

Set value: The value given by the customer corresponds to the flow of the medium, where the float top edge is aligned with a line on the sight glass.
