Page 6: Preparation
1. Preparation Preparation for testing is simple, quick and ensures you get the most reliable and accurate results from your testing. The FUNCTION Test and DIP Test both ensure the main unit and sensor are working correctly. CYLINDER PREPARATIONS ensure that you test on the best possible area of the cylinder wall. -
Page 7: Cylinder Preparations
CYLINDER PREPARATIONS: It is important to prepare the cylinders well to attain accurate and reliable readings. To perform CYLINDER PREPARATIONS: Step 1: Find on the cylinder the side which has the least damage, rust or chipped paint. For accurate testing you must find a vertical strip down the side of the cylinder which is as smooth as possible. -
Page 8: Calibration Procedure Identification (Cpi)
2. Calibration Procedure Identification (CPI) T he purpose of this test is to identify whether method 1 or 2 should be used for the cylinder being tested. The details and differences between methods 1 and 2 are explained in the next section. To perform CPI: Step 1: Place a strip of gel or water down the vertical strip on the cylinder you chose during CYLINDER PREPARATIONS. - Page 9 3. Testing PROCEDURE 1: TO BE USED WHERE HIGHER READINGS ARE FOUND IN THE GAS PHASE COMPARED TO THE LIQUID PHASE. Step 1: Place a strip of gel or water down the vertical strip on the cylinder you chose during CYLINDER PREPARATIONS. Step 2: Place the sensor on the area covered with gel or water and on the UPPER portion of the cylinder, where you are certain the sensor will be above the liquid level.
- Page 10 Below liquid level Note: Some cylinders are prone to giving ‘false levels’;that is the bar graph may disappear after moving the sensor even though the Liquid Level has not been passed. If you think you may have found a false Liquid Level, simply move the sensor slightly to the left or right to check if the bar graph returns, as false levels can usually be caused by irregularities in a specific part of the steel wall.
- Page 11 PROCEDURE 2: TO BE USED WHERE HIGHER READINGS ARE FOUND IN THE LIQUID PHASE COMPARED TO THE GAS PHASE. Step 1: Place a strip of gel or water down the vertical strip on the cylinder you chose during CYLINDER PREPARATIONS. Step 2: Place the sensor on the area covered with gel or water and on the LOWER portion of the cylinder, where you are certain the sensor will be below the Liquid Level.
- Page 12 Above liquid level Note: Some cylinders are prone to giving ‘false levels’, that is the bar graph may disappear after moving the sensor even though the Liquid Level has not been passed. If you think you may have found a false Liquid Level, simply move the sensor slightly to the left or right to check if the bar graph returns, as false levels can usually be caused by irregularities in a specific part of the steel wall.

Page 13: Troubleshooting
Troubleshooting ISSUE 1: “The readings on the main unit did not change when the sensor was placed anywhere on the cylinder” SOLUTION: Firstly, ensure you are using an adequate quantity of water or gel to couple the sensor to the cylinder and also ensure that the rubber pad of the sensor is clean and undamaged. - Page 14 ISSUE 3: “Readings are rarely/never greater than 1000 on the side of the level where the highest readings are found.” SOLUTION: The Portalevel ® Max should, in most scenarios, be able to attain readings of more than 1000 on a cylinder. Achieving readings less than 1000 DOES NOT always prevent measurement, but in some cases may cause problems.
- Page 15 ISSUE 4: “The bar graph does not fill up, even with CAL engaged” SOLUTION: The bar graph will only fill up if very high readings are found without CAL engaged, or once CAL is engaged and the current reading is significantly larger than the value displayed when CAL was pressed.
- Page 16 ISSUE 5: “Debris/gel in sensor housing has caused the sensor mechanism to stick making it hard to use.” SOLUTION: The sensor can be removed from its housing and cleaned following the below steps. Step 1: Hold sensor in left hand with dot/top facing up. With right hand, unscrew rear cap completely by twisting anticlockwise.
- Page 17 ISSUE 6: “There is not a significant difference between above and below level readings” Step 1: Carry out a ‘Calibration Procedure Identification’ (CPI) explained in Section 2.3, page 9. Step 2: Upon completing Step 1 press CAL on the exact location where the highest readings are found.

Page 18: Frequently Asked Questions
Frequently Asked Questions Why do I have to use water or gel with the sensor? The use of water or ultrasonic couplant gel is essential to the operation of a Portalevel ® unit. When the sensor both emits a high energy pulse and listens for the retuning echoes, excellent mechanical contact must be maintained between the senor and the container in order for the ultrasonic signals to pass into and out of the container efficiently and without interference. - Page 19 Why can’t I test CO and FE-13 in high temperatures? When testing some liquids, it is vital that testing is done under atmospheric temperatures lower than their critical temperature. At the critical temperature of a liquid, it transforms into a vapourous state in which a liquid level no longer exists inside the container to be measured.

The cable connecting the sensor to the main unit (B) threads through the hollow sections and out of the handle to avoid tangling. Using the adjustment nut and an Alan key, the sensor (F) can be loosened and slid horizontally along the adjustment rail (G).

Page 22: Portatherm
Portatherm (Optional Extra) ® Portatherm ® is an easy to use infrared thermometer which allows easy checking of a cylinders temperature prior to testing. This is useful when testing agents such as Carbon Dioxide or FE 13 in hot climates, which cannot be tested above their critical temperature. -

Low Battery: This is represented by an icon. Turn the unit off and replace the batteries with 2 x AAA batteries. Ensure the unit is off before replacing batteries. Cleaning: Clean the thermometer lens with a soft cloth or cotton swab and water/ medical alcohol. -
Page 24: Maintenance
4. Maintenance This section contains instructions on how to maintain the equipment to extend its lifetime as long as possible. Maintenance of the equipment is simple and only requires the cleaning of the sensor. For any major works or re-calibrations the unit can be returned to the manufacturer for repairs. -
Page 25: Battery Replacement
Battery Replacement You will need a small flathead screwdriver and a 9V alkaline type 6LR61 Battery. Step 1: Ensure the unit is off and turn the unit so that the front fascia faces downwards. Step 2: Take a small, flat head screwdriver and insert it into the slit at the bottom of the back side of the unit. -

5. Training This section is for new or untrained users, or for users who may need to remind themselves of how to operate a Portalevel ® The positions of the particular controls for the Portalevel Max are shown at the ®... - Page 27 The BENCH Test: Step 1: Connect the sensor to the Portalevel unit and turn the unit on. ® Step 2: Choose a vertical strip of your large container which is as continuously smooth as possible, free of chips, rust or any other kind of damage. Apply water or the ultrasonic gel along the length of this chosen vertical strip.
- Page 28 Step 6: Move the sensor back up the vertical strip of the cylinder, again in steps of roughly 5cm (2 inches), observing the bar graph each time you place the sensor onto the container wall. Be sure the vertical strip of wall you chose of the container is still well covered by whatever couplant (water or gel) you have chosen.
