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.
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.
Domino Software is Lowell Instrument's Python based, open source software for use with the data loggers and current meters. It is used forconfiguration and control of meters, as well as for conversion of binary data to useful formats. It can be downloaded here.
