Hoffer HP Series Flow Control Insertion

Hoffer HP Series Flow Control Insertion is designed for measuring liquid and gas flow in medium to large diameter pipes with accuracies inherent in the turbine flowmeter at a substantially lower price than in-line flowmeters.

Hoffer HP Series Flow Control Insertion

Several versions are available including fixed, adjustable, bi-directional and high pressure. In addition a number of process fittings and materials of construction may be supplied to suit the demand of various applications.
