® ® 1 General 1.1 Introduction Congratulations on your purchase of the Maretron Tank Level Monitor (TLM100). Maretron has designed and built your monitor to the highest standards for years of reliable, dependable, and accurate service. The TLM100 is used to sense levels of liquid tanks using ultrasonic technology and transmit ® the liquid levels over the NMEA 2000 network. This allows you to observe tank levels ® anywhere on the vessel where there is an NMEA 2000 compatible display s

® ® then be received back at the sensor component. Using the speed of sound, it uses this time to calculate the distance between the face of the sensor component and the surface of the liquid (or the tank bottom if the tank is empty). The cone width of the beam transmitted by the TLM100 sensor component is 6°. Please refer to Figure 1 below for a diagram of the waves emitted and received by the TLM100. Please note that due to limitations of ultrasonic technology, the minimum depth that

TLM100 User’s Manual • The sensor component of the TLM100 must be mounted over the deepest part of the tank, in order to obtain accurate depth readings when the tank is empty or near empty. • In order to obtain accurate readings when the tank is empty, the tank bottom directly under the TLM100 must be both smooth and flat, so that the ultrasonic sound waves transmitted by the sender are reflected back to the sender for measurement. If the tank bottom under the TLM100 is sloped, groove
