AgriFlo Series 3

Measure up to three flows with a single AgriFlo
• High accuracy with NO moving parts
• Measures flow practically anywhere
• Versatile straight run requirements
• Low cost of ownership

Doppler Ultrasonics
MACE Doppler instruments transmit an ultrasonic (sound) wave into the flow. This sound wave is reflected by acoustically reflective particles (e.g. air bubbles, suspended solids) and the instrument detects the reflected frequencies. The difference between the transmitted frequency and the received frequencies is directly proportional to the velocity of the stream flow.

Benefits
• AgriFlo supports up to three MACE velocity sensors
• Single full-pipe sensor can be used in pipes from 100mm (4″) to 2.5 metres (100″) in diameter
• Optional combined depth/velocity sensor can be used in open channel or non-full pipe applications
• Weatherproof, polycarbonate case that can be padlocked for added security
• Real time display of flow rate and total flow in user selectable units
• AgriFlo can “look” upstream or downstream
• Dual password interrogation for data access by irrigators and authorities
• Calibration function for use where less than ideal straight pipe lengths are available
• Built-in data logger
• Minimal pipe and flow obstruction
• Easy to install, easy to use and virtually maintenance free
• Accuracy better than 2 %
• Choice of either solar panel or mains powered charger

In full or partially full pipes, the velocity of the stream flow varies markedly across the cross-section of the pipe. Typically, velocity is zero along the wall of the pipe and increases to a maximum at or about the centre of the pipe. MACE Doppler instruments receive reflected frequencies from particles moving at these different velocities. The greater the area of flow moving at a particular velocity, the greater the number of reflections with the respective frequency shift. The average velocity of the stream is therefore calculated by averaging those frequency reflections received across the whole stream profile.
