ULM84 Rev.99-12 2- To retrieve the best wave response, the angle between the probe and the level should be right angle. 3- There should be no bubble on the liquid level. - Page 4 FAHM Co. Ultrasonic Level Transmitter Industrial Automation ULM84 Series User Manual Dec.2020 Doc. ULM84 Rev.99-12 serial number on startup and starts to search the level at the same time. Next, while still keeping the searching operation on, it displays the HART identification number (default to 00) and in case the search succeeded, calibration operation follows.

ULM84 Rev.99-12 Define Distance between Transmitter’s Probe to the Reference Point ( P04 Probe Height In order to calibrate the equipment, in addition to the reference level (with which other surfaces are measured), the end level of the probe and the maximum and minimum levels must be determined.
- Page 13 FAHM Co. Ultrasonic Level Transmitter Industrial Automation ULM84 Series User Manual Dec.2020 Doc. ULM84 Rev.99-12 For example, in Figure 19 there is an obstacle whose distance to the bottom of the transmitter probe is L₁; therefore, the "P06 Dead Band" parameter must be set to L₁ or slightly more; thus, the equipment will ignore the above obstacle.

ULM84 Rev.99-12 The errors in Figure 22 due to the following factors may be shown on the display. In the event of these errors, in addition to the displays shown in Figure 22, the alarm will be announced by the transmitter according to the user's selection based on the table above.

ULM84 Rev.99-12 Define equivalent level value of 4 mA current output according to the reference level( P49 4 mA Setup After defining the reference point, adjust this parameter to specify the minimum liquid level in a way that transmitter would output 4mA current when this level is detected.
- Page 18 FAHM Co. Ultrasonic Level Transmitter Industrial Automation ULM84 Series User Manual Dec.2020 Doc. ULM84 Rev.99-12 2- The minimum level value that the user expects, if the liquid is at that level, to have a 4 mA output current transmitter, is determined relative to the reference level and its value is entered in the "P49 4mA Setup"...
- Page 19 FAHM Co. Ultrasonic Level Transmitter Industrial Automation ULM84 Series User Manual Dec.2020 Doc. ULM84 Rev.99-12 If the above is done correctly, the amount of liquid level according to the figure is 7 meters above the reference level and the read number of the equipment up to the liquid level will be 2 meters; therefore, the number +9 must be considered for the probe level of the transmitter.
