I. Introduction I.1. Description GaugerGSM/485 is a mono-block ultrasonic level meter with integrated GSM cellular modem (GaugerGSM only) and USB interface. Optional items include display, external temperature sensor, dry contact input and relay. GaugerGSM/485 measures distance. Targets may be liquid or solids. Measurement is continuous and does not require contact with the target. The system can accurately measure steady or agitated target surfaces. The system can also rapidly track filling and emptying of vessels. GaugerGSM/485 (75 KHz) measures distance to liquid targets up to 8 meters and...

I.5 How to use this user manual I.5.1 Looking for specific tasks… First thing Read the description section in the introduction chapter. Review notices and safety guidelines. Review the section: Application dimensions and constraints in the reference guide chapter. Review the sections: electrical schematics and electrical connections in the physical and electrical installation chapter. Study the chapter: keypad and display. Then read the section about quick setup in the chapter that follows. Study the chapter: configuration with a PC while referring to the reference guide chapter as required....

II. Physical and electrical installation guidelines This chapter is a list of guidelines for proper physical installation of GaugerGSM/485 on tanks including electrical connections. Always ensure that GaugerGSM/485 is installed in an area that meets the stated ratings of the product including temperature and technical specifications. If you are using an EX-rated GaugerGSM model, read also the special instructions sections related to EX-rated models. The final section is a short and concise list of instructions – the “must-be pamphlet”. Gauger systems are installed above the target (e.g. water,...

GaugerGSM/485 should be perpendicular to the surface of a liquid target. The angular displacement should be less than 5° from the vertical axis. For solids in silos, GaugerGSM/485 should be aimed towards the center of the silo’s base. The sensor should be displaced from the center of the tank and oriented perpendicular to the solids surface when tank is at full state. Figure 4 - Silo (left) and liquid (right) examples Proper physical installation is accompanied by software setup. Setup includes defining parameters such as tank height and may include additional parameters such as NBD, FBD, False...
