1. Figure 1 TLM100 Operation 2 3 Choosing a Mounting Location The primary function of the TLM100 is to sense levels of liquid in tanks using ultrasonic technology and transmit this information over NMEA 2000 network so that tank level information can be viewed anywhere on the vessel where there is an NMEA 2000 compatible display The TLM100 tank level monitor consists of two parts 1 the sensor which mounts onto the top of the tank and contains the ultrasonic level measurement components and 2 the interface which converts the measured data into NMEA 2000 format and transmits the data over the NMEA 2000 network The interface component of the TLM100 may be mounted anywhere subject to the length of the cable connecting it to the sensor component The sensor component of the TLM100 must be mounted on the tank whose level is to be monitored Choosing a proper mounting location for the sensor component of the TLM100 is Revision 1 4 Page 3 TLM100 User s Manual critical to obtaining accurate tank level readings For best results please follow these recommendations The sensor component of the TLM100 must be mounted flat so that the round transceiver portion of the TLM100 faces straight downward 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 the2.

All of the Maretron adapters are designed to this specifications and anything smaller will cause the TLM100 to not work properly This means that the hole in the top of the tank if someone is cutting a hole must be 1 25 or more in diameter Any type of custom extension or any custom mounting technique which must be approved by Maretron Technical Support will require the entire apparatus to have a minimum inside diameter of 1 25 The bottom face of the sensor component must not come in contact with anything other the clean fluids If the gasket or any sealing compounds such as silicone come in contact with the sensor sound waves will be blocked or distorted causing the device to not work The adapters air locks or focus tubes must remain clean as any foreign objects may cause problems 2 3 1 Effect of Pitch and Roll on the TLM100 Assuming that the TLM100 sensor component is mounted on a flat tank top the TLM100 will operate correctly as long as the vessel does not experience pitch and or roll in excess of 6 for an extended period of time This can occur on a sailboat when the boat is heeled over or ona Page 4 Revision 1 4 Maretron powerboat with a non displacement planing hull Temporary pitch and roll due to wave motion and will not adversely affect tank level readings If you are in a sailing vessel or a powerboat with a non displacement hull and will experience pitch and or roll in excess of 6 for an extended period

Hole mounting pattern Maretron offers adapters to allow mounting the TLM100 on a tank with a 1 5 NPT connection or a 1 25 BSP connection WARNING e Gasket installs only one way and must be properly aligned to the tank and sensor for proper operation Use only supplied gasket other gaskets may obstruct and cause the device to not work do not use silicone sealant around the gasket Use only Maretron adapters others may have wrong diameter causing the device to not work Tank must have no obstructions within 6 beam angle for example baffles clean outs fill or vent pipes Tighten the bolts mounting the TLM100 to a torque of 10 15 in lbs 1 1 1 7 N m Over torquing the mounting bolts can result in erratic or inaccurate depth readings 2 4 2 1 Installation on a Tank with a SAE J1810 5 Bolt Fitting To install the TLM100 on a tank with a SAE J1850 5 bolt fitting place the gasket over the tank fitting so that the bolt holes line up WARNING the gasket must be properly aligned it only fits one way Place the TLM100 sensor component over the gasket so that the bolt holes line up Insert the mounting bolts through the TLM100 sensor component and gasket into the tank fitting the tank fitting may instead have studs installed so in this case install the nuts over the studs and tighten them to a torque of 10 15 in lbs 1 1 1 7 N m Do not use threadlocking compounds containing methacrylate ester such as Loctite Red 271 as
6. 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 grooved or rough then the TLM100 may not report an accurate level reading or any level reading at all when the tank is empty In this case a focus tube may be used The focus tube comes with a focus tube cap which can be mounted on the end of the focus tube after it is trimmed to size which ensures that the ultrasonic sound waves will be reflected back to the sender when the tank is empty even if the tank bottom is not flat Please refer to the Focus Tube Installation Instructions document for details The area below the sensor component of the TLM100 must be free of obstruction from tank baffles or return lines that might reflect ultrasonic waves back towards the sensor component causing inaccurate depth readings The sensor component of the TLM100 must be mounted away from the tank walls so that reflections from the tank walls do not cause inaccurate depth readings For a flat bottom tank the mounting hole in the top of the tank through which the TLM100 measures fluid level should be located as close to the center of the tank both front to back and side to side as possible This will ensure maximum accuracy of reading in the event that the vessel experiences pitch and roll The TLM100 requires a 1 25 diameter hole
7. tanks have the filler tube extend to near the bottom of the tank which prevents foam but if not it will take some time before you get a stable reading after filling the tank Testing the TLM100 outside a tank is not recommended The sensor has a hard time with instantaneous changes to the distance being measured which never happens when installed on a boat since the tank can t be filled or emptied instantaneously For example if you hold the sensor above a table at 10 and then move it away from the table to the floor 40 away the sensor experiences a step or instantaneous change that causes it to start range finding Sometimes it will quickly find the floor other times it will take a long time Please don t judge the TLM100 based on its performance outside a tank as this does not accurately reflect the operating conditions for which the TLM100 was designed 2 4 Mounting the TLM100 2 4 1 Preparation of the TLM100 Sensor Component The accuracy of the TLM100 can be affected by condensation of water or splashing of water or fuel on the surface of the ultrasonic sensor The TLM100 comes with a packet of petroleum jelly in order to repel the condensation Open the packet and spread a thin layer of petroleum jelly on the bottom face of the sensor component Revision 1 4 Page 5 TLM100 User s Manual 2 4 2 Mounting the TLM100 Sensor Component The TLM100 comes from the factory ready to mount on a tank with the standard SAE J1810 5

9. 0 The TLM100 is capable of sensing tanks up to 40 1 02m in depth It can be used for diesel fresh water grey water black water and oil tanks Unlike most tank senders that only work with rectangular tanks the TLM100 can be calibrated for irregular tank shapes so you know the true level of your tanks The TLM100 can be mounted on tanks with a SAE J1810 5 hole mounting pattern or to tanks using 1 5 NPT or 1 25 BSP threaded openings via available adapters The TLM100 has an optional airlock for black water applications to keep the face of the ultrasonic transmitter from fouling and an optional focus tube to allow use on boats with planing hulls when the vessel spends a significant amount of time with the bow pitched up or in tanks with bottoms that are not flat below the ultrasonic transmitter The Maretron TLM100 is designed to operate within the harsh demands of the marine environment However no piece of marine electronic equipment can function properly unless installed calibrated and maintained in the correct manner Please read carefully and follow these instructions for installation calibration and usage of the Maretron TLM100 in order to ensure optimal performance 1 2 Gasoline Tanks The TLM100 is NOT intended for use in tanks containing gasoline Use in tanks containing gasoline will void the product warranty For gasoline tank applications please use the Maretron TLM100 Gasoline Tank Level Monitor 1 3 Firmware Revisio
