2. INTRODUCTION

Ultrasonic sound, or ultrasound, is a sound wave with frequencies above 20 kHz, higher than the upper audible limit of human hearing. Ultrasound can be generated when turbulence created by air or gas is forced through a small oriﬁce. Leaking air or gas is generally considered to be viscous ﬂow, and as the ﬂow velocity increases, the frequency of the ultrasound emitted becomes higher. Vibrating, moving objects or electric discharge will also create an ultrasonic wave, which is very directional in nature and can be used to pinpoint the exact location of a leak, vibration or discharge.

The ULD-400-R Receiver detects ultrasounds within 20 kHz to 90 kHz frequency, then ampliﬁes and converts these ultrasonic sounds to frequencies and levels that the human ear can hear through headphones and show it on the LCD screen. The 20 kHz to 90 kHz frequency range is the optimal range for detecting a variety of leakage events in assets such as HVAC systems and pneumatic lines. A change in the ultrasound produced by an asset may be indicative that an asset is beginning to fail.

3.3 ULD-400-T Transmitter

The ULD-400-T Transmitter is included with the ULD-420 kit and is optional for the ULD-410 kit.

When a leak is not pressurized sufﬁciently the Receiver will not be able to detect it. In these circumstances, the ULD-400-T Transmitter can be used to emit an ultrasonic sound that the Receiver can read. The Transmitter is programmed with three signal levels for precise pinpointing of leaks.

3.4 Accessories

The ULD-400 comes supplied with additional Receiver accessories that are helpful in leak identiﬁcation. Plug the headphones into the Receiver to audibly hear the leak and verify its source (for example hissing sound of an air leak versus ticking sound of an electric discharge). Use the Parabola attachment in situations where there is a high level of background noise to help direct the ultrasound towards the sensor. Use the Tubular Extension with the Adapter in hard to reach areas for additional reach.

Note: There is no speaker on the Receiver. Without headphones, no noise will be audible.

4. MAIN APPLICATIONS

4.1 Using the ULD-400-R Ultrasonic Leak Detector Receiver

1. Turn on the Receiver and plug the headphones into the jack located on the front of the Receiver. Any standard set of 3.5 mm jack headphones are compatible.

2. Before moving to the target area, press “+” or “-” sensitivity buttons to adjust signal strength sensitivity to the highest possible level where bargraph still shows either 0 or a value close to 0. If signal strength cannot be adjusted down and the LCD still shows a maximum value regardless on sensitivity adjustments, press the Filter button.*

3. Scan the target area with the microphone sensor.

4. As you move nearer to the source of the leak, vibration or electric discharge, the signal strength will increase. This will be indicated on a screen with increasing signal strength number and level of the bargraph.

5. The bargraph is a relative measurement only, so when the signal strength reaches maximum, lower the sensitivity by pressing the “-” sensitivity button until the displayed signal strength is less than 75. Repeat this process until you have isolated the source of the ultrasound.

6. The audible sound emitted via headphones will help to verify the source of the leak, for example hissing sound of the air leak versus ticking sound of the electric discharge. The Receiver screen alone will not provide an indication of the leak source.

Note:

• For surroundings with a high level of background noise use the Parabola (PB-1) to direct the ultrasound towards the sensor.

• For locations that you cannot point the Receiver directly at the leak, the Tubular Extension can be used (TE-1 with the TEA-1 Adapter).

Figure 4.1a: Using the Receiver to ﬁnd a leak

4. MAIN APPLICATIONS

*ULD-400-R Filter Operation

In some situations, there might be strong ultrasonic noise generated by running machinery, motion sensors or other equipment. This noise will cause the Receiver to read the maximum signal strength on the display regardless of the sensitivity settings and make it unusable for detecting leaks.

In such cases, press the “Filter” button. The ﬁrmware will automatically detect the main noise frequency and ﬁlter it out by applying digital non-pass bandwidth ﬁlter within +/- 5 kHz. If the signal level does not decrease down close to 0, then the ﬁrmware will automatically repeat the process for other noise frequencies. Up to three frequencies can be ﬁltered out automatically. The ﬁlter icon will be displayed on the screen and will indicate the number of ﬁlters applied, from zero (no noise detected) to a maximum of three.

Figure 4.1b: Filter applied

Note: The ﬁlter will be applied to the visual signal indication on a screen (signal strength number and bargraph). The ﬁlter will NOT be applied to the audio frequency in order to preserve original sound of the leak and allow the user to better determine the source of the leak.

Note: When working with the Transmitter, make sure to apply the ﬁlter on the Receiver before the Transmitter is turned on, or in an area where the Transmitter signal can not be detected. Otherwise, the Transmitter signal frequency will be ﬁltered out and Receiver will not be able to pick it up.

4. MAIN APPLICATIONS

4.2 Using the ULD-400-T Ultrasonic Leak Detector Transmitter

The Transmitter allows for ultrasonic detection of openings in locations where there is no gas or air pressure, or the pressure is not sufﬁcient to detect the leak with the Receiver alone.

Typical applications include verifying tightness or pinpointing places of air, water or gas leaks in:

• Fluid or gas tanks

• Building windows, doors or roofs

• Car windows and windshields

• HVAC vents

• Refrigerant pipelines

The process involves placing the Transmitter inside an object (such as tank, house or a car), sealing the entryways and scanning the object from the outside with the Receiver to verify tightness and pinpoint potential leaks.

1. Turn on the Transmitter.

2. Select the output signal level using the “+” or “-” signal level adjustment buttons.

Note: High setting is the default setting. For most applications and speciﬁcally for large objects this setting is particularly useful. The High signal may cause the Receiver to read maximum value away from the place of the leak even when lowest sensitivity was selected. Press “-” once to get to Medium signal and press “-” again to get to Low signal

strength. Adjust signal level to allow for more precise pinpointing of the leaks.

3. Place the Transmitter inside the object to be veriﬁed and make sure entryways are sealed.

4. Preform leak detecting with the Receiver as described in section 4.1.

Figure 4.2: Using the Transmitter and Receiver to ﬁnd a leak

5. MAINTENANCE

5.1 Changing the Receiver Batteries

The ULD-400-R uses four 1.5 V AA (LR6) batteries (supplied). To replace the batteries, follow these steps:

1. Make sure that the Receiver is turned off.

2. Use a screw driver to unscrew the captive screw.

3. Remove the battery cover.

4. Replace the batteries as shown in Figure 5.1. Observe the battery polarity shown in the battery compartment.

5. Replace the battery cover and secure it with the provided screw.

Figure 5.1: Changing the Receiver batteries

5. MAINTENANCE

5.2 Changing the Transmitter Batteries

The ULD-400-T uses two 1.5 V AAA (LR03) batteries (supplied with ULD-420). To replace the batteries, follow these steps:

1. Make sure that the Transmitter is turned off.

2. Loosen the battery-door lock with a ﬂat screwdriver.

3. Remove the battery cover.

4. Replace the batteries as shown in Figure 5.2. Observe the battery polarity shown in the battery compartment.

5. Replace the battery cover to the lock position.

5.3 Cleaning

The only maintenance the ULD-400 requires is inspection and cleaning. Periodically wipe the exterior with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic hydrocarbons, gasoline or chlorinated solvents for cleaning.
