The float of a VA Flowmeter easily moves up and down in the conical measuring tube. The vertical position of the float, obtained as a function of the flow velocity of the measuring media, is an indication of the flow rate. This flow rate can be read directly on the scale of the measuring tube.

Flap Flowmeter
The primary measuring element is a flap, which is deflected by the flow of the medium. The deflection angle is a direct indication of the flow through the pipe.

Sight Glasses
Side Glasses are designed to visually monitor volume flows for common/high velocity, flow direction, high temperature or high pressure applications.
