FLO-GARD™ RCM INLINE FLOW SWITCHES |
RCM's broad range of flow switches provide economical solutions for equipment protection and  automation.
All FLO-GARD™ flow switches provide high reliability design with no paddles, or small flow paths to plug or stick. Switches are suitable for measuring dirty water containing particulates and debris. Switches may also be selected for gases and steam.
Wide range of sizes and materials for optimal selection.
Choose one or two field adjustable switch set points from 0.5 gallons per hour (1/2") to 3000 GPM (8"). All switches are independently adjustable from 15% to 100% of range.
Maintenance-free Design
FLO-GARDTM flow switches operate on the differential pressure principle and have no bearing or sliding surfaces to corrode and stick. Normal maintenance is NOT required.
Low Installation Cost
FLO-GARDTM flow switches include a terminal strip and splash-proof junction box for making field connections, eliminating the cost of providing a field junction box. |

 |
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 |
| |
| EXAMPLE: 3/4-1-20-A-1 S2 |
| This is the catalog number for a 3/4" NPT Series 1000 Flo-Gage of bronze construction, flow range of 20 GPM maximum scale, equipped with optional seals of Viton, and one single-pole double throw reed switch. |
