2-4 Gas Connections
Standard inlet and outlet connections supplied on the Model 5860 i are 1/
4" compression fittings for flow rates up to 10 slpm, and 3/8" compression
fittings for higher flow rates.
Optional 1/8 compression, VCO TM and VCR TM connections are available
upon request. Prior to installation, make certain all piping is clean and free
of obstructions. Install the piping in such a manner that permits easy
removal if the instrument is to be removed for cleaning or test bench
troubleshooting.
2-5 Installation (Refer to Figures 2-1 through 2-2)
Recommended installation procedures:
a. The Model 5860 i should be located in a clean dry atmosphere
relatively free from shock and vibration.
b. Leave sufficient room for access to the electrical components.
c. Install in such a manner that permits easy removal if the instrument
requires cleaning.
d. The Model 5860 i Mass Flowmeter can be installed in any position.
However mounting orientations other than the original factory
calibration (see data sheet) will result in a ±0.5% maximum full scale
shift after re-zeroing.
e. When installing flowmeters with full scale flow rates of 10 slpm or
greater, be aware that sharp, abrupt angles in the system piping
directly upstream of the meter may cause a small shift in accuracy.
If possible have at least 10 pipe diameters of straight tubing up-
stream of the Model 5860
i Mass Flowmeter.
