The simple design and lower cost of the TCM-1 make it feasible to measure current in many locations simultaneously.<\/p>\n<p>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 &#8220;brains&#8221; of a tilt current meter.<\/p>\n<p>The TCM-1 is field configurable for either low or high current range by simply adding or removing a calibrated ballast. Housed rugged PVC, with no external sensors, the TCM-1 is easy to deploy and recover. The built-in data logger includes a USB communication interface, a microSD flash memory card, and a long-life lithium battery.<\/p>\n<h3>Key Features &amp; Benefits<\/h3>\n<div>\n<ul>\n<li>Water velocity for a fraction of the cost of an acoustic meter<\/li>\n<li>Tilt compensated compass for bearing measurements<\/li>\n<li>Simple, rugged, low maintenance design<\/li>\n<li>Seaweed snag-resistant<\/li>\n<li>Change range in the field without software<\/li>\n<li>Temperature sensor accurate to +\/-0.1C<\/li>\n<li>8 GB memory card eliminates memory concerns<\/li>\n<li>Lithium battery allows continuous 4Hz sampling for more than 1 year<\/li>\n<li>USB 2.0 with standard cable and drag and drop data file offload<\/li>\n<\/ul>\n<h3>Operation<\/h3>\n<p>The TCM-1 Tilt Current Meter measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Moving water tilts the logger in the direction of flow. The TCM-1 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.<\/p>\n<h3>Data<\/h3>\n<div>\n<p>Windows\u00ae software is used to configure the TCM-1 for deployment and to process data and saved as text file (.csv).<\/p>\n<h3>Package Contents<\/h3>\n<ul style=\"list-style-type: disc;\">\n<li>MAT-1 Data Logger<\/li>\n<li>46 cm (18&#8243;) current meter housing<\/li>\n<li>Bronze &#8220;low-range&#8221; ballast washer and bolt<\/li>\n<li>Lithium battery (installed in logger)<\/li>\n<li>8 GB microSD card (installed in data logger)<\/li>\n<li>1 m (3 ft) USB A to micro-B Cable<\/li>\n<li>Spare O-ring (pre-lubricated)<\/li>\n<li>30 cm (12&#8243;) lanyard<\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The TCM-1 tilt current meter is ideal for measuring water velocity from inland to the edge of the continental shelf.
