What if I submerge my Levelogger deeper than the specified range?
The Levelogger 5, Levelogger 5 Junior and Levelogger 5 LTC can withstand over-pressurization of 2 times the specified range, e.g. a Model M10 can accommodate a fluctuation of 20 meters or 60 feet and still record pressure without damage. However, over-range accuracy is not guaranteed.
How long will the batteries in my Levelogger last and are they replaceable?
The Battery life of the Levelogger 5 is 10 years, based on 1 reading per minute. Readings that are more rapid will reduce the battery life. For example, if a Levelogger 5 is programmed in Continuous Mode at a sampling rate of 1 second, the battery will be depleted in approximately 4 months. The internal batteries are factory replaceable.
Note: The Levelogger 5 Junior has a battery life of 5 years based on 1 reading per minute and Levelogger 5 LTC has a battery life of 8 years based on 1 reading every 5 minutes.
Drastic temperature changes beyond operating temperatures might cause battery damage or reduced battery life.
Leveloggers have a lifetime factory calibration, and do not require recalibration if used in the specified range. Recalibration may be required if the Levelogger is over-pressurized by more than 2 times their intended pressure range, used in unsuitable environments, or physically damaged.
Yes, Levelogger 5 Series dataloggers are fully serviceable at Solinst. Please contact Solinst for service options and details for older generation dataloggers.
The operating temperature range in a liquid, for the Levelogger is between -20° to 80°C (-4° to 180°F). To avoid icing/ freezing and transducer damage, the easiest method is to lower the transducer to a point in the water column below the frost line or ice formation depth.
In water bodies such as shallow streams, wetlands or ponds where icing/freezing may penetrate to the bottom, install the Levelogger in a vented stilling well imbedded into the bottom of the water body beyond the frost line.
If this is not possible, place the Levelogger inside two elongated silicon, rubber or latex balloons filled with a non-toxic, non-corrosive anti-freeze solution or saltwater solution. Place the balloons in a section of perforated, 30 mm (1.25") ID pipe and install the logger in the monitored water. The antifreeze solution will protect the Levelogger from ice expansion at the pressure transducer, yet transmit any pressure and temperature fluctuations that occur.
Note: Although precautions can be taken, placing a Levelogger in a situation where the water may freeze solid can permanently damage the sensor.
The Levelogger 5 and Levelogger 5 LTC have a corrosion-resistant coating that is baked-on using polymerization technology (inside and out). In harsher chemical environments, you can protect the Levelogger using a balloon filled with non-corrosive/non-toxic fluid (tap water). As pressure changes, the fluid encasing the logger will transmit the pressure differential to the logger's pressure transducer, without exposing it to corrosive conditions.
How can I clean my Levelogger LTC Conductivity Sensor?
The pins of the LTC conductivity sensor are platinum-coated, therefore they should not be roughly cleaned or touched with any metal. They can be cleaned with a soft bristle brush, Q-tip, or cloth. Almost any acid solution can be selected to clean the sensor, provided it is highly diluted (generally less than 10% acid). The "soaking" time should be monitored and kept to a minimum. Refer to the Levelogger Series User Guide for further general maintenance recommendations.
