| Description |
 |
The Matheson
Instruments TF-1000 and TF-1050 Series Flowmeters are corrosion
resistant Teflon® flowmeters which are interchangeable with
most 65mm and 150mm scaled rotameters. There are no wetted
metallic parts to leach or interact with the fluids being
measured. This minimizes the possibility of particle generation
and makes these flowmeters ideal for use in high purity
applications.
The TF-1000 and TF-1050
Series Flowmeters feature a lightweight, non-wetted, anodized
aluminum frame; a borosilicate glass flow tube with glass or
sapphire floats for maximum corrosion resistance and optical
clarity; and, a high purity metering valve for maximum flow
control.
|
| Be
sure to request calibration data for the gas(es) you will be
measuring. The flow tubes are available with either 150 or 65mm
reference scales screened onto the glass. |
| The
glass metering tube is incorporated into Matheson's patented Tube
Cube®. The "cube," a unitized tube holder, aligns
the tube quickly and easily for simple tube installation or
replacement. The Tube Cube provides protection during handling,
reducing chipped tube ends, broken tubes and misalignment. The
1.5X scale magnification lens allows for an easier, more
accurate reading. Kalrez® seals are standard to assure a
positive sealing surface |
