Gilmont Size 0 Corrolated Flowmeters
Gilmont Size 0 Micro Flowmeter Models GF-1000, GF-1060 & GF-7060          
                                                                                                                                                                 
The Gilmont family of Size Zero Flowmeters provide extremely accurate measurement of the
flow rates of liquids and gases. Accuracy of this flowmeter is
+/- 5% of reading or +/- 1 scale
division, whichever is greater. The flowmeter comes with computerized calibration tables for
various floats (either for air or water) at STP. Flow charts and formulas are also included to
convert the scale readings for various liquids and gases. Flow analysis software to generate
flow charts specific to the application is also available.   Pricing on left. Delivery stock to 14
business days.

Flowmeter Stand Kit and Stand Components

The flowmeter stand kits includes an aluminum base with an integral bubble level (to insure
perpendicularity of the flowmeter to the bench top for maximum accuracy) a mounting rod and
two mounting clamps.
