Our Leveline series offers customers absolute and vented sensors for groundwater and surface water monitoring.
When you need a reliable water level logger for any type of water monitoring application, our industry leading LeveLine absolute range is the perfect solution for you. The Leveline has an impressive specification as standard at market leading prices.
Having strong and dependable equipment is essential when it comes to monitoring water levels effectively and accurately, and this is where the LeveLine range can help. Since each water level logger has been built with reliability and ruggedness in mind to meet the demanding needs of a wide range of monitoring applications, you can depend on its high quality to perform to the required standards. The strong titanium construction ensures that these loggers and sensors can withstand use in even challenging environments.
Each Leveline is lifetime factory calibrated and requires virtually no maintenance during it’s entire life. With our recently enhanced warranty offering you can have the extra confidence over our competitors. Aquaread supports all of it’s customers to the highest possible level, we offer training courses on the Leveline range to our customer to help them get the best from them.
Accuracy is essential during any water level monitoring application, no matter how challenging the environment. The inbuilt pressure sensor used in the LeveLine logger range has been designed to measure even the smallest changes to the surface or groundwater levels extremely accurately and recording the water temperature is also incredibly simple and efficient for maximum ease and convenience for the user.
The LeveLine range now also includes our impressive LeveLine CTD device which is able to record not only water temperature and level but also its conductivity and salinity. This opens up further application suitability to our customers such as tracer testing, saltwater intrusion or routine chemistry measurements along with level and temperature.
