Flow Rig Calibration

The calibrators use a piston within a smooth bore tube to act as a moving barrier between the pressurising gas and the displaced test fluid. It generates a continuous train of electrical pulses by use of a linear encoder/translator attached to the piston. Each pulse represents an extremely small but very precise volume of fluid. The unit is virtually immune to the effect of the test fluids viscosity and density in accomplishing its volumetric flow determinations. The calibrator consists of a precision honed flow tube, a flow piston and shaft, a photoelectric sensor (encoder) associated valves, supply tank, and an electronic console to interpret and display the data.
