| Drake Willock was the first hemodialysis equipment manufacturer to introduce a hemodialysis machine with a bicarb proportioner. |
| Speed brakes and fuel flow proportioner were inoperative without system A hydraulics, thereby confirming complete system failure. |
| The proportioner requires no electricity and operates using water pressure to inject the proper amount of chemical. |
| This high-pressure proportioner utilizes super-charged, high-pressure axial piston pumps for processing unfilled, nonabrasive, noncorrosive materials. |
| A fuel proportioner malfunction is a downing discrepancy, a fact known to all three. |
