Even as organic farming becomes increasingly more attractive to American and European consumers, global agrochemicals such as fertilizers (11.5% CAGR) and pesticides (8.9% CAGR) are growing at a record pace, due to increased demand from developing countries. In 2008, the Environmental Protection Agency (EPA) amended its policy on pesticide tanks and secondary containment to prohibit the use of external sight gauges for level indication on stationary tanks. The agency found that they would often break or become damaged in the field and were the number one cause of chemical leaks. Hence, opaque or black agrochemical tanks that require level measurement, must now use tank top mounted level sensors. At this commercial farm, EchoSpan ultrasonic level transmitters are installed in each of their fertilizer bulk storage tanks. The non-contact level sensors provide continuous level data to the PLC, which in turn, sends out periodic inventory data via text message to the chemical distributor for fertilizer replenishment.
