Page 5: Section I - Introduction
SECTION I – INTRODUCTION OVERVIEW The AT3 monitor is a microprocessor based, real-time, in-line instrument used to monitor liquid-borne particle concentration and oil contaminants in various process liquids. Use of the microprocessor and graphics display provides a user friendly interface for setup and calibration. Because it is acoustically based, Monitek’s patented transducer measures independent of the liquid’s color, opacity, density, flowrate or photosensitivity. - Page 6 Figure 1-1: Typical Return Reflections from Oscilloscope Trace. The far wall pulses and the main bang, although not counted, provide an indication of the operating characteristics of the transducer. Changes in these signals may indicate a transducer problem. At 128 times a second the AT3 sends out a burst of energy into the process liquid, turns around and listens for echoes that return to the transducer, and then analyzes the data to determine a measurement.

Page 7: The Front Panel
THE FRONT PANEL The AT3 uses a 240 x 64 dot liquid crystal graphics display in conjunction with a 24 key keypad as a user interface. See Figure 1-2. Three keys on the left and three on the right of the display are “soft”, having different functions depending on what appears adjacent to them on the display. -

SECTION II – INSTALLATION SYSTEM INSPECTION Check to ensure that all components of the AT3 monitor have arrived safely. Included should be: the AT3 system electronics, sensor, and cable set. If there is any damage to the equipment or if anything is missing, please contact the Monitek sales representative immediately. -

Slide probe back until safety cable is taut. Tighten Swage-Lok fitting. CAUTION: Galvanic Applied Sciences USA Inc. recommends that our AS3 probe should not exceed operating temperature of 80ºC without air cooling or 110ºC with air cooling. With the insertable probe configuration, the preamplifier and explosion proof enclosure are an integral part of the probe. - Page 10 FLOW )PAIR OF RG/8 CABLES PER SENSOR ASSY 1 BNC-BNC 10-15 1 N-N DIAMETERS PIPE DIAMETERS FLOW Figure 2-1: Typical Sensor Assembly Placement and Installation.

Page 13: Section Iii - Operation
SECTION III – OPERATION INTRODUCTION Once the system has been installed, the hardware must be set up for your particular application, and checked to ensure that it is operating properly. The system operates by sending out a 5 or 15 MHz RF pulse (depending of sensor type) to the transducer, where it is converted to an acoustic pulse. - Page 14 "CALIBRATION" Used to correlate raw data coming from the sensor to a corresponding concentration. Up to 16 different samples can be read by the instrument. From this information the instrument can construct a lookup table or perform a polynomial fit of degrees 1 to 4. The user can graphically plot the resulting curvefit to visually check how it corresponds to the samples.

Page 15: Menu Operation
MENU OPERATION All menu choices can be modified or activated merely by pressing the button corresponding to the menu item. If a screen contains more than six menu items the choice "<More>" will appear as the lower right menu choice, and pressing this will take the user to the next page of choices. See Figure 3- <2. - Page 16 Option list items, when pressed, allow the user to choose from a list of possible options. The user selects the desired option by pressing its corresponding button. The currently selected option is shown In inverse characters At any time "MAIN MENU" can be pressed to go back to the main menu screen. If "MAIN MENU" is pressed when already in the main menu screen, the instrument will return to the top screen (showing the instrument reading and the bar graph).

Page 17: Quick Start Up
QUICK START UP The "SETUP" menu. The parameters that can be chosen are: units (use the arrows), the resolution of the main display in digits to the right of the decimal point, and the instrument damping. See Figure 3-5. The "Display" menu allows the user to set the top screen to display "Raw Data"... - Page 18 2. The "Measurement Setup" menu. These are parameters that intimately affect the measurement and must be set before samples are taken. See Figure 3-8. If any of these are changed after samples have been taken, the measurement environment is different enough that the previous samples are no longer valid.
- Page 19 2.c. The "Threshold" value needs to be set above the noise yet not so high that echoes are not seen at all. NOTE: For concentration measurement, a good rule of thumb is to set the "Threshold" so that the typical process concentration gives a reading of 2000 counts (the total range is 0 to 5000).
- Page 20 3.a. Press "SAMPLE TABLE" and you will see a summary of the 16 samples. See Figure 3-12. If a sample has not been entered yet, it will read "INACTIVE". Otherwise it will display the raw data and corresponding concentration for the sample. The instrument prompts the user for a sample number (1 to 16), which is entered by the keypad.
- Page 21 3.b. The user must decide what type of curve fitting to perform on the data, and this Is done in the "Cal Type" menu. See Figure 3-15. Lookup Table Best Fit Line Cal Type: Best Fit Parabola Degree Poly 4 Degree Poly Figure 3-15: Cal Type Menu 3.c.
- Page 22 Table 3.2: Calibration Type and Number of Active Samples Required. NOTE: The user can try many different types of “Cal Types”; however, a “Fit Sample Data” must be done after any change to update the calibration. See Figure 3-17. If only a portion of the curve is of interest, the user can go into the “Partial Plot” menu and choose the desired range to plot (by specifying the Low and High X values).

Page 26: Section Iv Maintenance
SECTION IV MAINTENANCE GENERAL SYSTEM CLEANING: Disengage the A T3 from its power source before any cleaning. The unit can be cleaned with a soft cloth dampened with water. A mild detergent may be used if necessary. Do not allow water inside the unit. Also be sure that no water remains near the power connections to eliminate the possibility of electrical shock. -

SECTION V APPENDIX GLOSSARY OF TERMS Chamber: The short piece of piping in which the AT3 transducer is positioned (see sensor). Detection threshold: The level that the signal from an acoustic reflection must exceed before it Is counted by the receiver. A number from 1 to 255, it is usually shortened to DT. Far wall pulse: Acoustic reflections from the inside diameter of the pipe opposite the transducer. -
