WATER / WASTEWATER 25
Introducing the new LeveLine-CTD; water level, temperature, conductivity and salinity logger
LeveLine water level loggers offer outstanding performance at a competitive price with a 5 year warranty
The LeveLine range of water level and temperature sensors was launched by Aquaread in 2014. Within the last four years the range has seen huge successes both in the UK and overseas and has been used by both private customers and various governments to provide accurate and reliable data over a number of years.
The brand new LeveLine-CTD from Aquaread expands our range of highly accurate water level loggers to now include an all in one level, temperature, conductivity and salinity level logger.
The LeveLine-CTD is an ideal choice to measure level and conductivity levels in the following applications: Salt water intrusion and soil salination monitoring, Contaminant plume remediation monitoring and studies, Leachate monitoring at landfills, mine, waste disposal storage sites, Agricultural and storm water runoff monitoring, Tracer tests.
The leveLine-CTD is manufactured from titanium and is perfectly suited for long term deployment in the harshest of environments. It boasts leading accuracy, a huge 500,000 data point memory and direct SDI12/RS485 output. Absolute or gauge variants are available to cover all the usual applications from groundwater to surface water.
Easily add these sensors to a telemetric monitoring network via the standard SDI12/RS485 comms and combine them with our multiparameter Aquaprobes for a complete overview of both the water’s level and quality.
Here in the UK, A F Howland Associates have been using the LeveLine loggers for a number of years. Daniel Myhill, a Geotechnical Engineer A F Howland Associates says, ‘At A F Howland Associates Limited, we utilise Aquaread’s LeveLines alongside LeveLine-Baros to provide absolute water levels.
We mainly use them to provide information on the infiltration characteristics of the ground, in order to provide high quality data and efficient testing, providing our Clients’ with cost-effective results. By installing LeveLines, we’re able to undertake more tests concurrently as well as allow tests to run beyond normal working hours to capture information otherwise unobtainable.
To enable us to present the results in our in-house developed and commercially available software, GEODASY, we use the LeveLink software to process the results, turning pressure into depth. We are then able to calculate soil infiltration rates using the information gathered through our site investigation. In processing the data, we find the LeveLink software very easy to use, with helpful prompts and a very intuitive layout. The LeveLink software’s ease-of-use was a strong factor in choosing Aquaread’s dataloggers.
As one of Aquaread’s largest UK customers, we have always found their customer service friendly and their technical support ‘second-to-none’. They provide support well beyond the initial purchase and are able to respond to queries and undertake re-calibrations in a timely manner in order to minimise downtime.
Our relationship with Aquaread continues to grow because we believe their dataloggers are able to provide a cost-effective solution. If you are interested in any of the services we offer, please see our website

The range started with an entry level version called the LeveLine-ECO, made from stainless steel and a high-end version simply called ‘LeveLine’ that was made from high quality titanium. In 2016 Aquaread proudly announced that the complete range would be made from titanium, dropping the LeveLine- ECO from the range. A new entry to the range was launched the LeveLine- MINI, a smaller unit designed solely for use with telemetry systems or third party dataloggers.
In 2017 the latest addition to the range was launched. The LeveLine-CTD was introduced, capable of measuring a water level, conductivity, salinity and temperature. In addition the LeveLine-MINI-CTD was also rolled out aimed at the telemetric market.
The current LeveLine range includes the LeveLine, LeveLine-CTD, LeveLine-MINI and LeveLine-MINI-CTD. All units are made from high grade titanium providing maximum corrosion resistance in all applications. In addition each logger is available either as absolute (non- vented) or gauge (vented) depending on user requirements making the range very flexible.
LeveLine and LeveLine-CTD both come with 5 year warranty, thanks to its track record of reliability and offer a 10 year battery life. Batteries can be replaced once they have expired, these are not throw away items. A huge 500,000 data point memory is a standard feature of the LeveLine and LeveLine-CTD; operators can log up to 10 times per second on the LeveLine. This range of instruments is SDI-12/RS 485 compatible and they all have the ability to embed the GPS coordinates of each LeveLine and LeveLine-CTD into the data set when used with the LeveLine GPS meter. Operators can also download data from multiple LeveLine’s onto one LeveLine GPS meter. Despite all of these features, this range is very competitively priced and capable of out-performing many, more costly, water level loggers.

Aquaread launches a new miniaturised self-cleaning water quality probe
email: For More Info, email: email:
Aquaread has introduced a new multiparameter water quality probe featuring a new, much smaller self-cleaning system called the AP-6000. Before now, if automated cleaning of the probe’s sensors was required, the larger 77mm diameter AP-7000 Aquaprobe would have to be used. In certain applications, the size of this probe could be problematic, especially for bore-hole monitoring. The new AP-6000 has a diameter of only 55mm, making it a better fit for bore-hole based applications, whilst its smaller size reduces the cost of ownership.
The AP-6000 is supplied with all of the favourite water monitoring parameters such as pH, EC, dissolved oxygen, temperature and even depth. There are also 4 Aux sockets that allow you to add further sensors to the probe customising your data output, depending on the application’s requirements.
The small self-cleaning system is removable from the probe body and contains a small but powerful motor allowing the wiper brushes to rotate and clean all of the sensors fitted to the probe. Advantages of this set up include ease of maintenance and also a reduced power requirement, both of which are beneficial for unmanned deployments.
The AP-6000 is a versatile water monitoring probe. It is small enough to be supplied in a carry case for portable use with the GPS Aquameter, but thanks to its self-cleaning system it can also be deployed with an Aqualogger for a medium-term deployment. Where this new product shines is when it’s combined with a telemetry system to make your data accessible online.
Aquaread customers now have another choice for their remote monitoring requirements in the AP-6000 with its large number of measured parameters, small diameter, reduced power demand and lower cost of ownership. These features, in combination with a fresh and simple approach to telemetry, make it the ideal choice for effective long-term remote monitoring.
Follow Aquaread’s social platforms to be amongst the first to find out what other new and innovative products are due for release soon.
