Over-pressure protections to prevent system damage
Description
FlowTrac II is an intelligent, versatile pressure and volume control flow pump with all necessary components and sensors self-contained. There is no need for external values, pressure sensors, or gages for nearly all testing.
The flow pump, which regulates pressure and volume in a test cell, houses a high speed, precision micro-stepper motor that moves a piston in a water-filled cylinder. An embedded control board with a dedicated CPU uses readings from the internal pressure transducer to determine response of the stepper motor. The number of motor steps is used to compute volume change. Two-way solenoid valves are used to control the direction of flow (output valve) and fill/drain operations (supply valve).
FlowTrac II can maintain a desired pressure within 0.35 kPa (0.05 psi) while monitoring volume changes within 0.001 cc. Pressure increments may increase and decrease in any pattern by any amount (without exceeding the system’s limits) as specified by the user, even while a test is in progress.
