TAU003 Float-Type Flow Meter

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

If a medium with sufficient flow rate flows from bottom to top through a vertically inserted measuring tube, then the floated element raised so far, till an equilibrium between the lift strength of the medium itself and the weight of the floated element is adjusted.

Since the average flow rate is proportional to the flow quantity per time unit, the determined equilibrium corresponds to the flow volume. Flow meters with solenoid floated elements can be equipped with limit value contacts.
