H33 Propeller Velocity Flowmeter
Used to measure and record very low point velocities in water and other conductive fluids, this meter uses the change in impedance of a rotating multi-bladed impeller to indicate rotational speed caused by the flowing fluid. The fine diameter of the sensory head enables the meter to be used in small ducts and channels with an ability to measure fluid velocities as low as 25mm/sec.
A probe and digital indicator are required in combination to perform measurements but the digital indicator is supplied separately from the probes to allow an appropriate probe to be selected to suit specific applications.
