Description
The MiniWater 6 range of probes designed with at least two component parts. 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.
In anemometry, the accuracy achieved by a vane probe is acknowledged to be unmatched. The vane rotation is closely linear to flow velocity and is unaffected by pressure, temperature and density. In the Miniwater probes, as each metal blade passes the probe handle, a pulse is generated by a simple magnetic pick up in the handle. The electronics of the MiniWater 6 reads the pulse and converts these readings to a linear 0-1V output signal.
An initial starting flow velocity is required to overcome the initial stationary friction forces of the turbines. All outputs are ranged from 0m/s and the anemometers will provide readings below the initial start up speeds once the turbines have some momentum, allowing reading below the starting velocity.

Snap-Head Replacement
The snap-head fixing system renders it very simple to fit a new impeller to the flow probe: this saves costly non-productive time and in the event of weeds being tangle in the turbine or damage to the snap-head enables you to have the probe back in service in a matter of seconds by simply changing the snap-head.
Every MiniWater probe generate a pulse each time a vane blade passes the probe handle and the MiniWater 6 electronics converts the output to a linear 0-1V output. Each snap head and probe handle are paired and any replacement snap head should be of the same original size and flow range. Fitting an incorrect snap head will not match the probe handle and therefore the MiniWater 6 will no longer provide an accurate output.
The standard probes are a synthetic plastic construction snap head with an Aluminium vane turbine and handle. These units are designed for monitoring water flows in rivers and other water course, but can be use with flow of non-aggressive liquids.
