KOBOLD SWK flow meters and flow switches operate on the suspended-float principle, but without the use of a conical measuring tube. A float moves in the direction of flow against the force of a spring in a cylindrical guide tube. The float contains a permanent magnet, which operates an adjustable setpoint contact mounted on the outside. This rotameter and switch is compact and can be mounted in any orientation. The SWK is ideally suited for monitoring low flows in applications where low cost and high reliability are critical.
KOBOLD flowmeters and monitors of model SWK operate on the known suspended float principle, however without using the generally known conical measuring tube. An orifice float moves in the direction of flow against the force of a spring in a cylindrical guide tube. The float contains a permanent magnet which operates a floating sealed contact (read contact) mounted on the outside. The instruments are small and can be mounted in any orientation. Model SWK flow switches are ideally suited for monitoring low flows.
Flow switches are mechanical devices used in controlling the flow of air, steam, or liquid. A flow switch operates by conveying a trip motion (relay, reed switch, paddle) to another machine within the system, usually a pump. The trip signal will indicate to the pump to turn on or turn off. It is necessary to provide damage protection and circuit cooling or adjust flow rates that are too high or too low.
Definition of Flow
Flow refers to the velocity or physical movement of gas, steam, or liquid within a pipe that triggers the actuation of the flow switch. When there is no flow present, the velocity either drops or completely stops; in either case, the switch will revert to its original position.
Flow Switch Uses
Water flow switches are implemented in water sprinkler systems. In the case of a fire, for example, a flow switch can trigger an electrical fire alarm device to turn on.
