2. Liquid damper (Model AM3000/DL)

A damper mechanism is required for gas measurement especially in low-pressure applications to prevent hunting of the float.

The damper installed at the bottom of the flowmeter ensures the accuracy and durability of the flowmeter. The damping mechanism

reduces abrupt movements of the float by using the resistance generated between the oil in the damper and the damping element

connected to the float rod.

The liquid damper is also recommended for liquid applications with pulsating flows.
