Make sure all components have been removed from the packing material. Inspect all components for damage. Check the contents of the packing slip and report any discrepancies to the factory. Check the nameplate model number to be sure it agrees with the packing slip and purchase order. Check and record the serial number for future reference when ordering parts. Model Number Serial Number 1.2 Mounting 1.2.1 Transmitter Location The transmitter enclosure should be securely fastened to an appropriate supporting structure, in a location that permits easy access for maintenance. Avoid locations that are exposed to direct sunlight, flooding, high levels of radiated electromagnetic interference, and excessive vibration or shock. 1.2.2 Transducer Location Sunshade Model 384/385 transducers must be mounted directly over the material to be measured. Both floor and wall mount transducer brackets are available for use over open tanks or channels. Flange mounts are available for use with closed vessels. If mounted in a location where there is intense, extreme, direct sunlight, a sunshade is recommended. Proper mounting and wiring of the ultrasonic transducer is of the utmost importance. Both the accuracy and the reliability of the Model 344/345 can be adversely affected if the transducer is mounted improperly. NOTE: The 344/345 requires a blocking distance between the transducer and the maximum liquid level. The minimum blocking distance is 12 inches (305 mm) for Model 345 and 18 inches (460 mm) for Model 344. At temperatures above +140° F (+60° C) minimum, it is 18 inches for either model. Maximum blocking distance should be limited to approximately 10 feet (3 m) as this blocking distance is extended at the expense of the useful span over which the instrument operates.

Refer to Figure 3. 1. Open the door of the unit. 2. Drill holes in the enclosure as required for additional wiring. Be careful not to damage the printed circuit boards. Be sure that the PC boards are not damaged or contaminated when removing filings and/or debris from the housing. 3. Provide watertight seals for all wiring entrances in the enclosure to maintain the NEMA 4X rating. 4. Mount the enclosure to a wall or flat surface using the appropriate screws or bolts. The mounting tabs on the back of the enclosure can be rotated to the sides, or top and bottom to facilitate mounting. Refer to Figure 4. 5. Install conduit for power and control wiring. Be sure all connections to the enclosure maintain a NEMA 4X rating. 6. Close the door until it is time to wire the transmitter. Secure the door by tightening the six screws. Proceed to Transducer Mounting on the next page. Figure 3 Predrilled Conduit Openings NOTE: Do not overtighten the screws that hold the transmitter door closed. Do not use an electric or pneumatic drive on the screw. Overtightening can cause cracking of the housing, resulting in leakage into the housing. Figure 4 Transmitter Mounting Tabs Echotel Model 344/345 Ultrasonic Non-contact Transmitter 5 1.4 Transducer Mounting Requirements 1. Whenever possible, locate the transducer to avoid obstructions between the transducer face and the surface of the level being tracked. The ultrasonic signal is emitted from the transducer with a beam spread of approximately 12 degrees. Objects that extend into the ultrasonic beam can produce echoes that mask the true level. The false target buffering feature allows for blocking out up to nine obstructions inside the tank.

Position the transducer so that the radiating surface or transducer face is exactly parallel to the measurement surface. This will provide the strongest return signals and enhance the reliability of the Model 344/345. NPT Pipe Stub Maximum 11" (280 mm) or less Transducer This end welded or flanged to tank 3. In applications where the material level may come into the blocking distance or where the full tank height will be used, the transducer must be mounted in a short pipe stub (standpipe). The diameter of the standpipe should be at least 8 inches (200 mm) and its length should be limited to 11 inches (280 mm) from transducer face. Refer to Figure 6. NOTE: When mounting in a standpipe, performance is enhanced by using as short of a pipe as possible. 8" (200) Minimum I.D. Figure 6 Transducer Mounting in Standpipe 6 Echotel Model 344/345 Ultrasonic Non-contact Transmitter 4. Avoid installing the transducer in tank top openings that exhaust heated air or vapors. The boundaries between the vapors and the outside air often represent acoustic impedance gradients that can cause troublesome sound reflections. In those installations, the transducer should be mounted well away from the opening inside the tank, or in a pipe stub. Refer to Figures 6 and 7. 5. To prevent electromagnetic noise from disrupting the normal operation of the Model 344/345, it is recommended that each transducer cable be run in its own conduit, separated from other power cables and wiring. 6.

Refer to Figure 19. This connection for the RS-232 is utilized for the hook-up of a laptop computer. In the laptop mode, one can download stored data if unit is equipped with the data logging option. The cable to connect the laptop computer to the Model 344/345 must be supplied by the user. Configure this cable as shown in Figure 19. Downloading instructions are in the Laptop Section on page 39. 2.7 Transducer Synchronization Transducer synchronization is only available with the Model 344 unit. It allows you to run the cabling from multiple Model 384 transducers in the same conduit. This prevents the possibility for crosstalk to occur from one Model 344 to another. The synchronization scheme involves the use of one 344 unit operating as a master, and one or more other units operating as slaves. Multiple Model 344 units should be wired together utilizing TB8 (Figure 20) on the daughterboard as shown in Figure 21 below. The master unit synchronizes the ultrasonic signals such that all units transmit their ultrasonic signals at the same time. This eliminates the possibility of cross talk occurring. No calibration or configuration is necessary other than the wiring shown below. SYNC. IN SYNC. OUT GR. REF. Figure 20 (344 Daughterboard) Synchronization Terminal Block – TB8 SYNC. IN SYNC. IN SYNC.
