TLM200

Maretron's TLM200 ($600) monitors tank levels ultrasonically all the way down to the bottom—it's got a range of 104 inches. Ideal for diesel fuel, fresh water, or wastewater, the TLM200 uses sound waves rather than a probe inserted into the tank, so there's no immersed sender to foul or corrode. And because the sensor is NMEA 2000-enabled, tank levels can be monitored from any display on the network. Maretron, (602) 861-1707; www.maretron.com
