Product Description

The Digital Flow Calibrator combines the simplicity & versatility of a soap film bubble meter with the speed and accuracy of a microprocessor. With hands free operation, you can still see the bubble, but you also have precision of a digital display with accuracy of a quartz clock. No more tedious bubble formation, bubble watching, timing & flow-rate time calculation. The DFC-1 accurately calibrates air sampling pumps (vacuum or pressure), rotameters, orifices etc. quickly & reliably with accurate & reproducible results.
Principle Of Operation : The DFC-1 gas flow calibrator operates on the principle of traditional soap film flow meter which has been automated with the use of high technology infrared sensors, quartz timing & microprocessor intelligence to provide instant digital read out of gas flow rates. A soap bubble is used to trace the gas flow through a fixed volume high precision glass flow-cell. When the liquid soap bubble passes through the first sensor, it activates a quartz timer, which stops when the soap bubble passes through the second sensor. The microprocessor then calculates the flow rate & instantly displays it on a liquid crystal display.
Specifications :

Measuring Range : 1.0 cc/min to 5.00 Ipm with Auto Ranging facility to cover full scale range of 199.9 ml/min., 1999 ml/min., & 5.00 Ipm.
Display : 3½ digit Liquid Crystal Display with additional indication of LOW-BAT and various Self-Diagnostic System-Errors.
Function : On Reset- Key to reactivate the system after Auto-Shutoff (in 2 minutes when not in use)
Multi Single - Modes to effect the measurement continuously for multiple bubble or to limit it to the first bubble.
Average - Mode to average the last four readings.
Accuracy : ± 2010 of Reading
Flow Cell : Precision, Small-Volume Glass flow cell that is vertically adjustable to provide faster results for Low-Flow applications. It also accepts any type of soap solution. However for higher flow measurement, we recommend our standard solution.
Automatic Bubble : This innovative bubble formation mechanism provides adjustable and continuous stream Formation of bubbles for hands free operation. A large reservoir of soap solution provides long uninterrupted operation without cumbersome process of re-filling after every few minutes.
