Animal Waste DischargeMetering farm waste discharges is becoming an increasingly important endeavour. Due to EPA discharge laws, animal waste from farm enterprises such as: dairies; hog farms and slaughterhouses must be measured as critical information is needed on the amount of waste entering settling ponds and also being re-used for irrigation.

Farm Outlet/Turnout MeterMurrumbidgee Irrigation based in the Riverina district of New South Wales, is one of the largest privately owned irrigation companies in Australia. It supplies water to approximately 3000 customers through a network of pipes and channels in excess of 2,500 miles long... Historically these deliveries were metered using a simple paddle wheel device known as the Dethridge wheel. However, although the Dethridge wheel provided a degree of accuracy (+/- 15%) this was deemed unsuitable for water delivery into the 21st century. Read more...

Flume and Weir MonitoringMany large open channels have been historically monitored using a flume or weir structure that has been "rated" using empirical data. Typically this rating is based on the depth of the water running over/through the structure. In recent times, the use of flumes and weirs has been negated somewhat by the advent of cheaper area/velocity methods, such as the MACE Doppler ultrasonic. Read more...

Gross Water Off-TakesQuail Mesa Ranch is a large irrigation ranch based near Ehrenberg, Arizona, USA. The irrigation water... is distributed along a large concrete lined trapezoidal canal (approximately 35 ft (10.5m) in width)... the water in the canal is actually diverted on farm through three, large diameter (47" or 1200mm) pipes...With the advent of the MACE Series3 AgriFlo, these pipes could now be metered with highly accurate Doppler ultrasonic technology, whilst also meeting the budgetary constraints of the irrigation enterprise.

Metering Lateral DiversionsLateral diversions are generally deep underground with limited access and even more limited metering options. Combined with silt and trash-laden stream flows, the large pipes often associated with lateral diversions used by irrigation water-supply companies to distribute water usually mean either expensive meters or no meter at all.

Open Channel Aquaculture MonitoringThe use of "area-velocity" methods, such as that provided by the Doppler ultrasonic MACE AgriFlo to measure flow in open channels, not only negates the need for costly civil structures, but also increases the overall accuracy of the measurement. Furthermore, with a MACE AgriFlo, it is possible to measure flow in open channels of an irregular shape, such as earthen channels or those cast in situ. Read more...

Partial-Pipe Wetland MonitoringThere are countless numbers of pipes across irrigation districts and individual irrigation farming enterprises 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.

Pump Station DischargeMetering surface water that is pumped from rivers or channels is a challenge that often fails traditional mechanical meters. The stream flows are usually trash-laden and moving at very high velocities (some in excess of 5 m/s (15ft/s)). The wear and tear on a mechanical meter under these conditions is immense, and consistently leads to failures and expensive repairs. Read more...

Sewer Lift Station MonitoringLifting 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. Read more...
