Proteus industries-0504SN2流量开关 Section 1 Introduction 500 Series Metering Flow Switches have been created to provide a more effective monitoring and control capability for applications in which liquid flow rates up to 4.5 GPM (17 LPM) must be monitored and controlled over extended temperature and pressure ranges. Capabilities required for extreme operating conditions have been incorporated in the basic product, allowing the size-reduced metering flow switch to be used in situations in which specialized products were previously required. The 500 Series Metering Flow Switches have been developed from Proteus’ experience in satisfying the needs of thousands of demanding users in widely diverse applications since 1978. Note The flow response of 500 Series sensors and thus their calibration may be dependent on the form of the device attached to the inlet connection and other closely located up-stream devices. Elbows, T-pieces, valves and filters located immediately up-stream from the flow sensor can introduce swirling motion to the liquid flow. The swirling motion reduces the linear velocity of the flow stream. We recommend that a straight run of pipe of more than 10 x pipe ID (~4 inches or 10 cm) be used between the flow sensor and any up-stream devices to minimize these effects. Appropriate calibration procedures must be used to provide an accurate flow measurement with elbows or T-pieces that must be attached directly to the inlet connection.
