Portable Flow Meter for Open Channel Flow Measurement

Portable Flow Meter for Open Channel Flow Measurement

Quick Overview

This unit utilises the MiniWater6 Mini probe and the LogBox DA data logger to provide a versatile and accurate portable measurement and logging device for the measurement of water flows in open channels, tanks and chambers. The measurement range up to 10m/s. Optional sensors for temperature, distance, level and rainfall.

Details

The MiniWater 6 probes are designed with a snaphead vane anemometer and a probe handle. The probe handle contains all the electronic components and comes with 2m cable with flying leads. All plastic snapheads are designed to be replaceable with an Aluminium vane for use in river and water courses to measure the flow rates. The MiniWater vane anemometers are available in two different sizes: Micro and Mini, with two different flow ranges available for each: 0-5ms; and 0-10m/s.
