Multi-Application:
Uses include: barrel heating fluids, thermal transfer
fluids and non-steam water monitoring. |
| • |
Rugged
and Reliable:
Designed as a hydraulic service tool, this monitor will
provide years of maintenance free performance. |
| • |
Three
Materials of Construction:
Select from aluminum, brass or stainless steel. |
|
| • |
High
Pressure Operation:
The magnetically coupled follower allows operation to
6000 PSIG and use with opaque liquids. |
| • |
Unrestricted
Mounting: Allows
the designer to install the monitor in any orientation
-- horizontal, vertical or inverted. |
| • |
Twenty-three
Different Ports Available:
Standard selection of NPT, SAE and BSP permits system
design versatility. |
| • |
Good
Viscosity Stability:
A thin (.03") sharp-edged orifice provides excellent
stability of readings to a minimum of 500 SVS. |
| • |
