Model FM-1000 Series (65mm)

Description

The FM-1000 Series Flowmeters incorporate the innovative design of the FM-1050 in a more compact unit without reducing standards of accuracy. This is the rotameter of choice for those interested in conserving space. The same ±5% full scale accuracy is guaranteed for the 65mm scale length of these flowmeters.

Unlike the FM-1050 series which use reference scales, the FM-1000 Series flowmeters are direct reading for air, and are available in either English or Metric units. Choose between a black glass or a stainless steel float. These flow tubes are fluted to provide better float stability.

The FM-1000 Series glass metering tubes are enclosed in the Tube Cube®. Protection of the tube, magnified tube scale for easy reading and alignment during replacement are afforded with this unitized holder. Integral fluted float guides for optimum float performance are standard with all tubes unless otherwise specified.

Like the FM-1050 there are three valve options available:

No valve for those who just want indication
Utility (six-turn) valve for those who desire control as well as indication
High accuracy (fifteen-turn) valve for very precise control

Design Features

Rugged, compact design
Precision tapered, fluted metering tube
Tube Cube® unitized glass tube holding assembly
Reflective plastic background and 1.5 X magnification lens for excellent readability
Safety blow-out back panel
Full 10 to 1 (100% to 10% full scale) metering range
Low pressure drop for increased flow rates at low feed pressures
Easy installation and quick service access
Optional utility and high performance valves do not require special fittings
Corrosion resistant options: all wetted parts of 316 stainless steel or Monel® with Viton® or Teflon® seals
Custom scales and flow curves available
