Combined with a submerged siphon structure, the MACE AgriFlo has been used extensively throughout Australia and USA for metering water supplied to irrigation farmers.
Generally, an insertion sensor is mounted through the wall of the pipe and the cable is routed to the pole-mounted AgriFlo electronics module. With all cables routed either underground and/or through the mounting pole this provides an extremely tamper and vermin resistant design. A solar panel is used to charge the internal battery, thus making the AgriFlo a truly remote electronic flow meter.
By utilizing a full pipe structure, the accuracy of such an outlet is increased when compared to open channel (or non-full pipe) configurations. Field accuracies better than 2% are easily obtainable. This degree of accuracy leads to far better management of the overall water resource.
Because the MACE insertion velocity sensor provides very little obstruction to the flow and has no moving parts, there is no measurable head-loss and the whole system is virtually maintenance free.
