| Pneumatic
In-Line Flow Rate Monitors |
|
|
 |
| • |
Three
Materials of Construction: Select
from aluminum, brass or stainless steel |
| • |
Rugged
and Reliable: These
monitors are constructed with all metal pressure vessels,
allowing safe, permanent, installation in industrial
systems. |
| • |
Unrestricted
Mounting: Allows
the designer to install the monitor in any orientation;
horizontal, vertical or inverted. |
| • |
High
Pressure Operation: The
magnetically coupled follower allows operation
to 1000 PSIG. |
| • |
Superior
Exterior Design: Can
be used outdoors and on systems where wash downs are
required. |
|
| • |
Twenty-three
Different Ports Available: Standard
selection of NPT, SAE and BSP ports reduces the amount
of adapters required for installation. |
| • |
Multi-Use: Versatile
monitors can be used to verify air compressor outputs
and to test pneumatic machinery and tools for proper
air consumption. |
| • |
Low
Cost Precision: Mid-scale
measuring accuracy: within ±2.5%. Full-scale
accuracy: within ±4%. |
