The TCM-4 Shallow Water Tilt Current Meter is ideal for measuring water velocity in shallow coastal ponds, bays, rivers and tidal flats and other locations where the depth is too shallow for the TCM-1 current meter. The TCM-4 is only 10 inches (25 cm) long and is able to operate in less than one foot of water.
Operation
The TCM-4 Tilt Current Meter measures current using the drag-tilt principle. The data logger is buoyant and is anchored to the bottom via a short flexible tether. Moving water tilts the data logger in the direction of flow. The TCM-4 contains a 3-axis accelerometer and 3-axis magnetometer for measuring tilt and bearing. The resulting orientation data is converted to current by applying calibration coefficients.
Specifications
See "TCM-4 Product Data Sheet" for more detailed specifications.
Data
Domino software for Windows is used to configure the TCM-4 for deployment and to process data and saved as text file (.csv).

$1200-1600 each depending upon options. For a quote based on your exact requirements, please contact us or by phone at 508-444-2616 or email: sales@lowellinstruments.com.
Anti-Fouling Paint Option:
Depending on the deployment duration and fouling intensity of where you are working, we recommend applying anti-fouling paint to the meters. We can add it for you for a small fee.
We recommend ePaint EP2000 for clear tropical waters, which is relatively environmentally friendly. For turbid waters, we recommend Interlux Trilux 33 which contains a biocide.
