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.
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.
