Savonius Rotor Type Current Sensor (Wading Rod)

A Savonius rotor-based current sensor designed for measuring water current velocity during wading-based river measurements.
The Savonius Rotor Type Current Sensor (Wading Rod) is designed to pick up water current with sensitivity in all directions. Its sensing method does not introduce mechanical or magnetic load, allowing very low threshold values required for model-tank measurements. The system provides direct current-velocity readings through an electronic meter with an LCD display and uses a Savonius rotor for sensing very low water velocities.

Overview

The Savonius Rotor Type Current Sensor (Wading Rod) is designed to measure
water current velocity with sensitivity in all directions. It is particularly
suitable for applications where very low water-current velocities need to
be detected, including model-tank studies.

The sensor uses a Savonius rotor to sense water current. The sensing method
does not introduce mechanical or magnetic load, allowing the sensor to
operate with very low threshold values.

Key Features

  • Savonius rotor type current sensing
  • Sensitivity to water current in all directions
  • Suitable for very low water velocities
  • Direct current-velocity measurement
  • Electronic meter with LCD display
  • Low threshold value
  • Suitable for model-tank applications
  • Stainless steel, Delrin and ABS plastic construction
  • 2.5-metre standard cable
  • Longer cable available if required

Measurement Principle

The water current is sensed using a Savonius rotor. As water flows past
the rotor, the rotor responds to the current and provides a measurement
of the water-current velocity.

The sensing arrangement is designed to pick up water current without making
mechanical or magnetic load, providing a very low threshold suitable for
model-tank applications.

Applications

  • Model tank studies
  • Water current measurement
  • Low-velocity water-current measurement
  • Hydrodynamic model studies
  • Experimental water-flow measurements
  • Laboratory water-current studies

Current Velocity Measurement

The sensor provides a direct reading of water-current velocity in metres
per second. It is designed to measure current velocities from very low
values up to the specified measurement range.

Electronic Display

The sensor is supplied with an electronic meter featuring a single
readout for current. The measurement is displayed directly on an LCD
display.

Water Current Sensing

The Savonius rotor is used for sensing water current from very low
velocities. The sensor is designed to provide sensitivity in all
directions, making it suitable for water-current measurements in
experimental model environments.

Construction

The sensor uses stainless steel, Delrin and ABS plastic in its construction.
These materials are used for the sensor assembly and supporting components.

Cable Configuration

  • Standard Cable Length: 2.5 metres
  • Extended Cable: Longer cable can be provided if required

Carrying Case

The equipment is supplied with carrying cases for transporting the sensor
and the hand-held reader.

Monitor up to 32 sensor channels simultaneously, with real-time recording, graphical monitoring and wave-data analysis from a single system.
