 |
Select a switch with a maximum flow range greater than the required switch point. Best performance at minimum pressure drop occurs at approximately 50% of maximum flow range.
|
| |
| Select a) body size, b) end connections, c) material, d) maximum flow rate, e) options (if required) and f) number of switches. |
| |
| A) BODY SIZE |
| pipe size at the meter inlet. Select from Standard Flow Ranges and Sizes |
| |
| B) SERIES (end connections) |
| 1 - threaded units provided with FNPT connections standard. FBSP parallel threads available on request for bronze meters. |
| 2 - wafer units mount between any standard 150 or 300 class flanges (or international equivalent). |
| |
| C) MATERIAL |
| 1 = Bronze 3 = Stainless steel (316) |
| |
| D) FLOW RATE |
| (maximum) - Select from Standard Flow Ranges and Sizes, page 2. Prefix full scale with "M" for metric units. |
| |
| E) OPTIONS |
| Select from table of Options. Note: For gas service, select option I and specify gas being ---------measured, inlet temperature and pressure |
| |
| F) NUMBER OF SWITCHES |
| 1S2 - One single pole double throw switch 2S2 - Two single pole double throw switches |
| |
| G) IS - Intrinsic Safe Approval (Included w / 1S2 or 2S2 Only). |
