| Variable
Area Flow Meters |
|
 |
| • |
Three
Materials of Construction: Select
from aluminum, brass or stainless steel. |
| • |
Flexible
Mounting Requirements: Allows
the designer to mount the monitor in any orientation;
horizontal, vertical or inverted. |
| • |
Superior
Exterior Design: Weather-tight
for use outdoors and/or on systems where washdowns are
required. |
| • |
Reverse
Flow Capability: An
option not found in most rotameters and other variable
area meters. |
|
| • |
Good
Viscosity Stability: A
thin (0.03"), sharp-edged, orifice provides excellent
stability of readings to a minimum of 500 SUS. |
| • |
Rugged
and Reliable: Designed
as a hydraulic service tool, this monitor will provide
years of maintenance free performance. |
| • |
High
Pressure Operation: The
magnetically coupled follower allows operation to 6000
PSIG and use with opaque liquids. |
| • |
Twenty-three
Different Ports Available: Standard
selection of NPT, SAE and BSP permits system design
versatility. |
| • |
Reverse
Flow Capability: An
option not found in most rotameters and other variable
area meters. |
