The TCM-4 Shallow Water Tilt Current Meter (left) is similar to its older brothers the TCM-1 (middle) and TCM-3 (right) except that it is designed to be used in water as shallow as 1 ft (30 cm) depth. It has a carbon fiber housing and integrated MAT-1 data logger. The result is a current meter that is optimized for coastal ponds, rivers and bays where "skinny" water is common.
Lowell Instruments will be at Ocean Sciences in Portland Oregon February 5-9th. Look for us in the exhibit hall booth # 314.
