Erdco Flow Meters

The 700 Series Flex-Flo™ meter is a simple and rugged flow rate indicator for air, water and other transparent fluids. It is particularly well adapted for applications that fall within standardized flow ranges at moderate pressures and temperatures.
The 700 Series features a rugged cast aluminum housing with metal threaded connections, a full air tempered glass window and the ability to install the meter in horizontal (left to right) and vertical (up or down) flow orientations - all at an economical cost.
The unique wedge shape of the housing enhances the self-cleaning capabilities of the meter which has large internal cavities that resist accumulations of foreign material. Unlike other variable area tube and float designs, the Flex-Flo™ may be installed in a horizontal piping system or even in down flow applications.
