Three
Materials of Construction:
Select from aluminum, brass or stainless steel construction
to meet system requirements. |
| • |
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
6000 PSIG. |
| • |
Twenty-Three
Different Ports Available:
Standard selection of NPT, SAE and BSP ports permits
system design versatility. |
| • |
Multi-Use:
Factory calibrated for phosphate ester. These versatile
monitors can be used to verify hydraulic power unit
outputs and to test machinery and tools for proper fluid
flow rates. |
| • |
Low
Cost Precision:
Mid-scale measuring accuracy: within ±2.5%. Full-scale
accuracy: within ±4%. |

Calibration Fluids:
DTE 25 @ 110ºF, 0.873 sg. Monitors are density
corrected to 1.16 sg. |
1 To determine
approximate measuring ranges multiply the range listed in
the Liquid Flow Rate section of Lake's Guide to standard
monitor numbers by 0.93. For example, a P3A6WB10 would have
a scale range to 10 GPM * 0.93 = 9.3 GPM at full scale.
