CURRENT AND FLOW METERS

Valeport have specialized in Current Meters and Open Channel Meters for over 50 years.  Whether you require a traditional impeller mechanism or high accuracy electromagnetic type, Valeport has a solution.  Choose from configurations suitable for a range of applications including handheld measurements in small streams, modelling experiments in the lab, and self-contained instruments for navigable rivers, estuaries, ROVs and the deep ocean.

Valeport's impeller instruments use the simple premise of measuring the speed of rotation of a helix in the water. PTFE bearings eliminate the need for specialized lubricants and the magnetic contact closure minimizes the moving parts in the system, allowing the sensor itself to be remote from the measuring electronics (ideal in deepwater applications).

The electromagnetic sensors use the Faraday Principle to measure the water speed. As water moves through an electromagnetic field (generated by the sensor), it generates a voltage that is measured by the sensor electrodes. Modern-day signal conditioning electronics and filtering techniques allow highly accurate measurements to be made, and there is a choice of sensor shapes and sizes to suit the application. The solid-state sensors and standard titanium/polyurethane construction provide excellent corrosion resistance and depth ratings up to 5000m.

Model 106 Current Meter

The Model 106 is the ideal instrument for coastal and estuarine applications and other light-duty survey work.
A low cost, lightweight alternative to larger flow meters, it is purpose-built for applications where the superior durability and depth rating of Valeport’s larger meters is not necessary. The instrument is manufactured from titanium and polymers, giving excellent resistance to corrosion, whilst maintaining a small size and low weight. Utilising the standard Valeport 125mm diameter impeller, the Model 106 features speed and direction parameters as standard, with further options of temperature and depth. Data (logged or real time) is compatible with Valeport’s DataLog™ software.
