Paddle-wheel flow controller for On/Off control

Transcription

1 Paddle-wheel flow controller for On/Off control Type 803 can be combined with... Indication, monitoring, transmitting and On/Off control in one device Programmable s (transistor or relay) Automatic-calibration: Teach-In Communication - external setpoints and process value (4-0 ma) Type 70 (8630) Type 067 Type 8644-P AirLINE Type 804 Type 8030 Control valve with TopControl Continuous SideControl Valve island with electronic I/O Flow sensor only with 803 remote Flow sensor only with 803 remote This intelligent controller with display is designed for use in clear, neutral or aggressive liquids and specially to switch a valve and to establish a monitoring system or an On/Off control loop. The switching points can be programmed with the 3-key keypad under the display or optionally, for the compact 803 only, from an external source over a 4-0 ma loop. The compact 803 is proposed with On/Off, or with external setpoints and process value s. The remote 803 has a transistor. The connection to the process in the piping is done with standard INLINE fittings.

The signal is provided via cable plug according to EN and/or a M multipin connector. The wall-mounted flow controller 803 is built up with an electronic module SE3 associated to a wall-mounted holder. The signal is provided via two M multipin connector. When liquid flows through the pipe, the 4 magnets, inserted in the paddle-wheel set in rotation, produce a measuring signal in the transducer. The frequency is proportional to the flow velocity of the fluid. A conversion coefficient (K factor, available in the instruction manual of the fitting), specific to each pipe (size and material) enables the conversion of this frequency into flow rate. Operation and display The device can be calibrated by means of the K-factor, or via the Teach-In function. Customized adjustments, such as engineering units,, filter, bargraph are carried out on site. The operation is specified according to three levels: Indication in operating mode / Display - measured flow - high threshold value - low threshold value Parameter definition - engineering units (International measuring units) - K-factor / Teach-In function - selection of switching mode (window, hysteresis) (see main features) - selection of threshold value (see main features) - delay - filter - 0-segment bargraph (select min. and max. value) Test - switching threshold test with flow simulation (dry-run test operation) To scroll-up the menu or increase a value To scroll-down the menu or select a digit to be modified Large digital display with 8 characters (4 digital characters and 4 alphanumeric characters) Bargraph Confirm input and menu points Status of the switching (red LED) p. /6

3 Main features 803 with external setpoint option. The switching points are automatically adjusted by the 4-0 ma input signal originating from a PLC. - Power supplied by the PLC - On/Off relay 803 with standard On/Off - switching modes for the, either hysteresis or window, inverted or not Hysteresis mode Window mode Hysteresis, inverted Hysteresis, not inverted Window, inverted Window, not inverted - Programmable delay before switching - Possible s depending on the version: relay, transistor NPN, transistor PNP, frequency 803 with process value option. This version delivers an electric signal whose value is the image of the measured quantity. - On/Off relay ma - external setpoint (4-0 ma input) Installation The 803 flow controller can easily be installed into any Bürkert INLINE fitting system Type S030 by means of a Quarter-Turn. Minimum straight upstream and downstream distances must be observed. According to the pipe s design, necessary distances can be bigger or use a flow conditioner to obtain the best accuracy. For more information, please refer to EN ISO 67-. EN ISO 67- prescribes the straight inlet and outlet distances that must be complied with when installing fittings in pipe lines in order to achieve calm flow conditions. The most important layouts that could lead to turbulence in the flow are shown below, together with the associated prescribed minimum inlet and outlet distances. These ensure calm, problem-free measurement conditions at the measurement point.

Pressure and temperature ratings must be respected according to the selected fitting material. The suitable pipe size is selected using the diagram Flow / Velocity / DN. The controller is not designed for gas flow control. p. 3/6
