It does notprovide instructions for detailed configuration, diagnostics, maintenance,service, troubleshooting, or installations. Refer to the Rosemount 3107 and3108 Reference Manual for more instructions. Manuals are availableelectronically on WARNINGF ailure to follow these installation guidelines could result in death orserious injury.

2 The Rosemount 3107 and Rosemount 3108 are Ultrasonic must be installed, connected, commissioned, operated, andmaintained by suitably qualified personnel only, observing any nationaland local requirements that may apply. Use the equipment only as specified. Failure to do so may impair theprotection provided by the could result in death or serious injury. Installation of the transmitters in a hazardous environment must be inaccordance with the appropriate local, national, and internationalstandards, codes, and practices. Please review the Product Certificationssection for any restrictions associated with a safe installation.

3 Before connecting a handheld communicator in an explosiveatmosphere, ensure the instruments are installed in accordance withintrinsically safe or non-incendive field wiring practices. Verify that the operating atmosphere of the transmitter is consistentwith the appropriate hazardous locations surface may be hot. Care must be taken to avoid possible leaks could result in death or serious injury. Install and tighten process connectors before applying pressure. Do not attempt to loosen or remove process connectors while thetransmitter is in shock could cause death or serious injury. Ensure that the transmitter is not powered when making connections.

They can be connected directly to a plant controlsystem, or used with a Rosemount 3490 Series Control Unit forprogrammable control of operationEach transmitter is designed to be mounted above a liquid, and usesultrasonic pulses to continuously measure the distance to the liquid microprocessor-controlled electronics calculates distance to the liquidlevel from the time delay between the transmitting and receiving of programmed with the bottom reference of the application usuallythe bottom of a tank the transmitter will calculate the liquid depth (level),and output the level (Figure 2-1)

6 As a 4 20 mA signal and a digital HART Rosemount 3107 and 3108 can also calculate contents (volume) oropen channel flow, and then output the result as a 4 20 mA signal and adigital HART is achieved by remote communication using 2019 Quick Start GuideQuick Start Guide5 Figure 2-1: Typical ApplicationA.

8 If the equipment is likely to come into contact with aggressivesubstances, it is the responsibility of the user to take suitable precautionsthat prevent it from being adversely affected, thus ensuring that the typeof protection is not compromised. Aggressive substances are acidic liquids or gases that may attack metalsor solvents that may affect polymeric materials. Suitable precautions are regular checks as part of routine inspections, orestablishing, from the material's data sheet, that it is resistant to specificchemicals. The equipment should only be cleaned with a damp cloth; do not usesolvents. The transmitter is double insulated, and therefore protective earthing isnot required.

9 However, the cable screen should be connected (see Figure5-1). Note that if the equipment is used in a manner not specified by themanufacturer, the protection afforded by the equipment may beimpaired. This transmitter is classified Type A in accordance with the EuropeanEMC directive 2004/108/EC. To ensure electro-magnetic compatibility,in any member state, it should not be installed in a residential is not advisable to mount the transmitter in close proximity to a source ofelectrical noise such as a variable-speed drive, or other high-poweredelectrical Rosemount 3107 and 3108 Ultrasonic transmitters are Intrinsically Safe(IS) approved for hazardous area Start GuideAugust 20198 Rosemount Ultrasonic 3107 Level and 3108 Flow Transmitters The Rosemount 3107 is designed for open or closed tank installation.
