| High Temperature Flow Rate Monitors
|
 |
| • |
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. |
| • |
Low Cost Precision: Mid-scale measuring accuracy: within ±2.5%. Full-scale accuracy: within ±4%. |
|
| ENGINEERING SPECIFICATIONS: The high temperature in-line flow rate monitor shall:
| • |
use the variable annular orifice technique with compression spring recovery. |
| • |
not require inlet or outlet straight plumbing or require vertical pipe mounting.
|
| • |
have a measuring accuracy of ±2.5% of full scale in the center third of the measuring range and ±4% of full scale accuracy over the entire flow measuring range.
|
| • |
have a stainless steel sharp-edged orifice.
|
| • |
have a minimum temperature rating of: H-series 400ºF (204ºC); J-series 600ºF (315ºC) |
| • |
be Lake Monitors No.: H _ _ - _ _ _ - _ _ for 400ºF (204ºC) applications; J _ _ - _ _ _ - _ _ for 600ºF (315ºC) applications. |
