QI have a project that requires non-Ambisense equipment, can I use that and still use Ambilytics?

Ambilytics can integrate data from almost every IoT environmental sensor, and can, therefore, be used on a very wide range of environmental projects.

Contact us with the details of your equipment, and we’ll confirm compatibility.

QMy project is a single site project – is Ambilytics only for large projects?

No, Ambilytics is designed to bring efficiencies on projects no matter their size. As with most software, it is infinitely scalable, but is also compatible with all IoT connected sensors and so can be used on almost any environmental project. Request a demo and see how it would work for you.

QIs Ambilytics not just an environmental data management tool?

While Ambilytics can be used as a data management tool, it is so much more. It uses machine learning to analyse, model, and identify trends and patterns in your data.


QOther than gas, what other mediums do you work in?

We provide groundwater and surface water solutions, geotechnical, and indoor and outdoor air hardware solutions.  Our environmental software, Ambilytics, is compatible with any IoT connected device and can be used on any environmental impact assessment project.

QWhat devices can be used in conjunction with a single GasfluX?

Due to power constraints, a GasfluX can be deployed with a water level setup or a dissolved gas probe – but not both.

QCan elevated concentrations of methane affect the TVOC?

VOCs can be measured with a PID using any lamp without any influence from methane/low C range alkanes so you should be okay with the PID. The TVOC concentrations unlikely to be interfered by concentrations from methane as these are not ionised / detectable using any of the lamps – methane has an ionisation energy of 12.6eV.

QDoes the water level logger need a barodiver / does the data recorded by the unit need to be compensated?

The water level loggers are vented and therefore there is no need to compensate the data.

QDifferent VOCs have different response factors when measured using a PID sensor - how is this factored in?

We calibrate VOC units with isobutylene which has a response factor of 1. VOC PID readings are always taken as indicative readings and not absolute values. Absolute values of any constituent VOC gas would require a lab-based test. Isobutylene is used by sensor manufacturers and considered a solid middle ground to use.

QWhat are the max and min borehole sizes that the GasfluX can be installed in?

50mm is standard but we can also install a GasfluX in a 35mm borehole if required.

QYour equipment is not located down the well, but instead feeds pipes down the borehole. Could you confirm how the well is sealed during monitoring?

A rubber bung that the tubing goes through seals the wellhead.

QIs it possible to run a sensor in a low light area?

Yes, a Li-ion battery can be used to power it (max.28 day deployment with hourly sampling).

QIs your equipment protected against unlikely water ingress into the tubing?

Yes, a water trap is in line at the inlet. The very high pressure recorded by the unit would also alert us to an issue.

QHow many GasfluX units are required on a site?

There is no set number or guidance which states the number of GasfluX units required.  The risk assessor will need to base this upon the Conceptual Site Model so that they can investigate/test the plausible contaminant linkages and provide sufficient information for their risk assessment. This is usually a targeted strategy, normally at receptor points (point of ingress into buildings) but also deploy in boreholes which intercept potential pathways and potential sources so a thorough understanding of the sites gas regime can be established.

QHow does your sub-floor void monitoring equipment monitor beneath buildings, does it need to be affixed to the wall and will holes need to be drilled?

Yes – holes would need to be drilled and the unit bolted to the wall.

QHow well does GasfluX cope with shallow ground water?

We fit humidity filters to the feed line to prevent water ingress but we recommend that GasfluX units are only installed where the SWL is below 600mm and that there is a clear section of response zone to allow gas ingress from the ground.


QMy project is in a very remote location, can you guarantee that there will be no break in data transmission

All our equipment was designed with this possibility in mind. We can use 2G, 3G or 4G networks, LoraWAN, Satellite or NBIoT depending on requirements.

QDo you offer any support if I start using one of your products?

Our team of experts are always available to answer your questions and make sure that your project is managed effectively.

QHave you ever had an issue where you have been unable to replace headworks?

We haven’t had an issue with replacement of old headworks to date but each site and headworks need to be assessed on its own merits and level of reinstatement and how well it has been concreted in to place.

QShould we have headworks be sent to us in advance of a project with Ambisense?

Yes, our mobilisation team will need the headworks there and fixed ahead of their visit.

QHow quick can we get your environmental hardware onsite, and are they installed by yourselves?

We have a large fleet of units and can provide these at short notice depending on availability of an engineer, normally between 5-10 days from order but we can mobilise quicker in times when required. We provide an engineer to mobilise and install the instrumentation (and decommission) as part of the service. This excludes the installation of headworks of course and timeframes will depend on availability and time to replace the headworks. The units can be installed 24 hours after installation of the headworks and we endeavour to do this within the timeframe required.


QDo you sell into the North American market?

Yes, Ambisense can provide our environmental risk assessment software to companies based in most locations around the world including the US and Canada.
