Overview of the PLI Digital liquid level gauge
With all the features of the original PLI , the fully American Bureau of Shipping (ABS) Type Approved PLI Digital has the ability to take a reading from cylinders in poor condition, or suffering from a layer of rust. It also has an in-built thermometer (in both C & F), an easy-to-read digital display, one-button-set-up function for faster cylinder testing and smart plug, which enables the signal strength to be monitored by an audio signal from an internal speaker.
The complete PLI Digital liquid level gauge kit includes:
- PLI Digital liquid level gauge
- Protective leather case and hand strap
- Piezoelectric sensor
- 94cm three-section telescopic extension
- 125ml bottle of couplant
- Full operating instructions
- 8 x AA rechargeable batteries (4 spare)
- Foam-lined red polymer carry-case

*Please note when the unit is being used to determine the level of liquid CO2, an ambient temperature of over 27ºC will not give a result, as above this temperature the CO2 changes state from a liquid to a gas.
How to operate the PLI Digital
1. Wipe clean the cylinder in the area that the sensor is to be placed and apply couplant to the sensor. Place the sensor in an area known to be above the liquid level. Always orientate the sensor so the white dot is at the top.
2. Place the sensor in an area known to be above the liquid line. The reading on the display may show anything between 5 and 12. To calibrate the PLI Digital unit, press the SET button, the screen will say SETTING and the display bargraph will rise or fall until it reaches 10; you will hear a double bleep and the screen will say SET.
3. Place the sensor in an area known to be below the liquid level. The meter should read towards 0 but not below 0.
4. As the sensor is moved upwards towards the liquid level the meter will start to move towards 10. When the whole of the sensor footprint is above the liquid level, the meter will read 10. When the sensor is at the liquid level the gauge reading will read a value of between 10 and 0. What you are looking for is the large change in value between a reading below the liqui level and one above the liquid level. A reading of approximately 5 at the liquid level is suggested.
