OVERVIEW
The TCM-5 is a current meter that is designed to operate in the Abyssopelagic and Hadalpelagic Zones to a maximum depth of 10,000 meters. The TCM-5 is constructed from toughened syntactic foam with a titanium pressure housing and is intended to be deployed on benthic landers or by an ROV.
Similar to the other Lowell Instrument’s TCMs. The core of the TCM-5 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. The built-in data logger includes a USB communication interface, a microSD flash memory card, and a long-life lithium battery.
Key Features & Benefits
- 10,000 meter depth rating
- Water velocity for a fraction of the cost of an acoustic meter
- Tilt compensated compass for bearing measurements
- Simple & rugged design is easy to deploy from a ROV
- Internal temperature sensor is accurate to +/-0.1C
- 8 GB memory card eliminates memory concerns
- Lithium battery allows continuous 4Hz sampling for more than 1 year
- USB 2.0 with standard cable and drag and drop data file offload
- Easy meter configuration and data conversion with Windows® software (free download).
Operation
The TCM-5 Tilt Current Meter measures current using the drag-tilt principle. The logger is buoyant and is typically attached to the bottom via a short flexible tether to an anchor. Moving water tilts the logger in the direction of flow. The TCM-5 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 with the included software.

SOFTWARE
Lowell data loggers and current meters require software for communicating with and converting the data from their hardware. There are currently two versions available for download:
Domino
Domino, our newest software, is recommended for operation of all TCM and MAT data loggers from Lowell Instruments LLC.
- Domino is faster and more capable than our legacy software (MAT Logger Commander).
- Domino is open source so as to maximize transparency and encourage collaboration.
- Domino is compatible with both Windows 10 and Mac OS (Beta Test).
- Domino has replaced MAT Logger Commander. Click below to download it.
