HEATEC ASPHALT METERING SYSTEM
Provides continuous metering of asphalt cement for drum mix plants. Uses two pumps and is known as "a pump pushing a pump." The system can be calibrated to an accuracy of plus or minus one-tenth of one percent (0.1 percent). One pump is active and the other is passive. The active one is motor-driven and acts as a conventional supply pump. The liquid AC causes the shaft of the passive pump to rotate and operate an encoder. It generates a signal that provides flow information. A strainer is included.
