Lowell Instruments TCM-1 General Purpose Tilt Current Meter
The TCM-1 measures current using the drag-tilt principle. The logger is buoyant and is secured by a flexible tether to an anchor, stake or tripod. Moving water tilts the logger in the direction of flow. A 3-axis accelerometer and 3-axis magnetometer determine tilt and bearing. The meter also contains a thermistor for recording temperature.

Affordable & Easy-to-Use Current Meter
The Lowell Instruments Tilt Current Meter Model 1 (TCM-1) records water velocity in an affordable, easy-to-use package. The TCM-1 is ideal for measuring water currents in a variety of coastal environments including tidal estuaries and reefs out to the edge of the continental shelf. The low cost of the TCM-1 makes it affordable to deploy meters in many locations simultaneously, thereby increasing spatial data density.

| Explanation | The TCM-1 measures current using the drag-tilt principle. The logger is buoyant and is secured by a flexible tether to an anchor, stake or tripod. Moving water tilts the logger in the direction of flow. A 3-axis accelerometer and 3-axis magnetometer determine tilt and bearing. The resulting orientation data is converted to current by applying calibration coefficients. The meter also contains a thermistor for recording temperature. The TCM-1 is field configurable for either low or high current range. The electronics are housed in a rugged PVC case with no external sensors. The TCM-1 is very easy to deploy and recover, even from small boats. The built-in data logger includes a USB communication interface, a microSD flash memory card, and a long-life lithium battery. Windows® software is used to configure the TCM-1 for deployment and to process data saved as text file (.csv). The core of the TCM-1 is the MAT-1 Data Logger. The MAT-1 data logger was designed for NOAA and is ideally suited as the "brains" of a tilt current meter.
Specifications
Anti-Fouling Paint OptionDepending on the deployment duration and fouling intensity of where you are working, we recommend applying anti-fouling paint to the meters. For a small additional fee, the meter can be ordered with it already applied. |
