Flow Rates are calculated as <code>(flowRate * 2) - 1</code> and ranges from <code>-1</code> to <code>1</code>. On the x-axis this changes flow direction from East (<code>-1</code>) to West (<code>+1</code>) and on the z-axis from North (<code>-1</code>) to South (<code>+1</code>). | Flow Rates are calculated as <code>(flowRate * 2) - 1</code> and ranges from <code>-1</code> to <code>1</code>.
