Uncomplicated measurement of flow rates No magnets; uses inductive sensor Long working life thanks to high quality ceramic axis and special plastic bearing Run-in and run-out sections are not necessary. ● Uncomplicated measurement of flow rates ● No magnets; uses inductive sensor ● Long working life thanks to ceramic axis and special plastic bearing ● Run-in and run-out sections are not necessary. ● Modular construction with various connection systems ● Plug-in and rotatable connections ● Analog output and switching output ● Designed for industrial use ● Small, compact construction ● Simple installation ● Simple to use ● Cable outlet infinitely rotatable ● Optionally, non-return valve, Characteristics The flow meter consists of a spinner which is rotated by the flowing medium. The rotor's rotational speed is proportional to the flow volume per unit time. The rotor is fitted with stainless steel clamps (optionally titanium or Hastelloy®). An inductive proximity switch records the rotational speed, which is proportional to the flow rate. The FLEX transformer on the sensor has an analog output (4..20 mA or 0..10 V) and one switching output, which can be configured as a limit switch for monitoring minimal or maximal, or as a frequency output. The switching output is designed as a push-pull driver, and can therefore be used both as a PNP or an PN output. The state of the switching output is signalled with a yellow LED in the switching outlet; the LED has all-round visibility.
