Streamflo Velocity Meter

WaterFlow & Velocity Measurement & Monitoring

The Streamflo series of instruments are used to measure, indicate and record very low velocities of water and other conductive fluids.

Quantity

Overview

Designed primarily for laboratory and specialised industrial use, the miniature head of the flow sensing probe can be inserted into small ducts and channels where it has the ability to measure velocities as low as 5.0 cm/sec. It is thus suitable for measuring accurately the velocities in hydraulic models of river estuaries, dams, harbours, etc., in addition to field measurements of clean water flows.
