TM1 Wireless Tank MonitorInstruction ManualNov 2018DescriptionThe TM1 Remote Tank level Monitor consists of a self contained battery operatedcellular transceiver fitted into an enclosure with batteries, having a submersiblepressure transducer attached, that is lowered into a tank of liquid to be monitored forlevel.The plastic enclosure has a lower threaded mounting at its base that allows it to befitted through a hole atop a tank, or onto an external flange.A chemical resistant cable extends from the sensor to a lower entry point in the TM1underbody.A set of three “D” cells are enclosed that power the electronics and the Cellular modem.The TM1 utilizes the LTE CAT M1 service provided by Verizon Wireless in the USA thatoperates in the 750 MHz cellular 4G band.
The TM1 can be used to send a tank level report over the cellular link at repeated timeintervals and on a schedule. The number of reports can be altered by command but istypically set to once every 4 hours.Contact your supplier, agent or FLEET data service provider for changes to reportingschedules and times.The data packet it sends is only several hundred bytes in length and includes pressurereading, battery health, temperature and signal level information.It utilizes a CAT M1 Modem that allows transmissions over the Cellular network,permitting short burst data transfers to conserve battery life.Installation and ActivationThe TM1 must always be mounted upright, in the open, clear of any metallic shields orobstructions and within the propagation footprint of a Verizon LTE cell tower.Drill a mounting hole that is 1.75” ( 45 mm) Diameter at the top of the tank such that it isat the highest point or above the maximum liquid level.NOTE: The TM1 has slots at its mounting flange that will allow liquid to drain to theoutside of the tank if the liquid level is above the lowest point on the TM1 body. This isto stop any liquid forcing its way past the gasket and into the TM1 body. If the filling portis above this level, fit an extension tube or fitting to the tank so that it holds the TM1above the refilling port level.Lower the transducer into the tank and as it feeds through the hole feed it through thetightening nut provided.Allow the transducer to lay horizontally flat at the lowest part of the tank.Tighten the mounting nut onto the TM1 mounting flange.Once the TM1 is in place, remove the small magnetic keeper from the side of the TM1body. This will initiate the transmission and registration with the FLEET server andshould bring up a reading on the device page or dashboard on FLEET.The Magnet can be used at any time to disable the TM1 for transporting or troubleshooting. To reboot the TM1 insert the magnetic keeper with the engagement slot facingdownwards. Hold it there for about 15 seconds and then remove it.Save the magnet for future use.
Servicing the TM1From time to time, depending on the reporting frequency, local cell tower signal strengthand climatic conditions, the three “D” cell batteries will require replacement.(i) If the TM1 is in a Hazardous location, remove it to a safe location first.(ii) Then insert the magnetic Keeper.(iii) Remove the four screws holding the base and the upper cover using a Philipsscrewdriver.(iv) With the top cover removed, observe the location of the batteries and the waythey are held in place.(v) Cut away any zip ties allowing the batteries to be carefully removed.OBSERVE the battery polarity. Two on one side have POSITIVE facing UP andthe single battery on the opposite side of the board should have the Negativefacing DOWN.(vi) Replace the three “D” cells with top quality long life batteries such asDuracell “Quantum” or Energizer “Ultimate”.Select ones having at least 5 years shelf life.Do NOT use rechargeable batteries.Do NOT use old batteries.Do NOT mix battery types or old ones with new.(vii) Make sure polarity is correct and use two zip ties thro holes in PCB provided tohold the three cells in place. Make sure the ties are clear of other componentswhen tightened. Cut off any excess zip tie.(viii) With the two-battery set facing you, carefully refit the top cover with the magnetickeeper to your left. Screw the 4 screws tightly ensuring proper engagement ofthe top and the base.(ix) Make sure the magnetic keeper is installed correctly for 15 secs before removingfor activation.DO NOT TAMPER or ATTEMPT ANY REPAIRS YOURSELF.Always contact your supplier for service, repairs or changing device factory settings.
FCC ComplianceSection 15.21 Information to userChanges or modifications not expressly approved by the party responsible forcompliance could void the user's authority to operate the equipmentSection 15.19 Labeling requirements:This device complies with Part 15 of the FCC Rules.
