DBSF-K and the DBSF-1RE Flow Switches have been designed for the monitoring of liquids in pipes from 1 to 8 inches. (25 to 200 mm Diameter.)
The Flow Switch is particularly suitable as a No Flow or Low Flow protection switch for general industrial plants, Sprinkler Systems, Anti-Fire Systems, Steam Boilers and Irrigation Plants.
The standard unit is available with a 1 inch BSP brass fitting and stainless steel paddles. However, a full stainless steel version is available for sea water and more aggressive media.
The flow switch may be mounted in any position with the arrow in the direction of flow.
For best results, the flow switch should be kept away from elbows, valves, bends etc. Care must be taken when installing the paddles near the bottom of pipes to prevent slags from jamming the smooth operation.
To maintain accuracy, 5 pipe diameters of straight pipe should be provided upstream and downstream of the flow switch far from filters, valves etc.
For maximum sensitivity, cut the paddle to the maximum possible length which will not foul the bottom of the pipe fitting.
The DBSF-1RE is more sensitive than the standard model DBSF-K and can detect smaller flows in standard or larger diameters of pipe. This is of partiular importance on pressure systems or pumps controlled by variable speed drives.
