Solutions for wastewater flow monitoring & telemetry
Stormwater flow monitoring
With increased urbanisation, storm water run-off has become an increasingly important problem. Storm water pollution, protection and mitigation can only be effective if the storm water flows themselves are monitored and quantified, not only for pollutants but also volumetrically. Learn more…
Sewer flow monitoring
As increased living densities occur through urban areas, more pressure is being exerted on the ability of the sanitary sewerage systems to cope with the demands being placed upon them. It is critical that permanent sewer flow monitoring is undertaken on major catchments to assess the ongoing capabilities of all sewerage infra-structure. Furthermore, the accurate measurement of industrial inflows to the sewerage system is also increasingly important so that distribution of the costs of treatment can be fair and equitable. Learn more…
Flow monitoring through road culverts
Most water districts have countless numbers of road crossings through which storm water and water channels are flowing. They can take the shape of a typically “boxed” section or a round pipe (both full or partially full). Road culverts therefore, provide an extremely precise cross-section through which to measure flow. Learn more…
Flow metering in partially full pipes
There are countless numbers of pipes across water districts and wastewater networks that do not run full all the time. Whilst from a measurement perspective it is preferable to measure flow in a full pipe, from a practical viewpoint it is often either difficult to achieve full flow under all conditions or just not economic to change.

Sewer lift station flow metering
Lifting and conveying sewage through gravity sewerage systems and force mains requires monitoring to ensure that system capacities are not under or over-utilised. Moreover, the amount of effluent entering, being treated and discharged from sewer treatment plants is a critical measure. Learn more…

Open channel flow measurement
Historically, the measurement of flow in open channels has been undertaken using civil structures such as flumes and weirs. Whilst these structures do provide a reasonably accurate measure of the stream flow, in practice, flumes and weirs often suffer from neglect over time and provide less than favourable conditions for flow measurement with stage measurements and rating tables. This may be particularly the case for structures that are several years (if not decades) old, and were designed for measuring different flow rates than may exist today. Learn more…
