Page 8: Modular Flow Meter System Ts
5. Modular Flow Meter System TS The flow meter operates according to the positive displacement principle. In a housing fitted with inlet and outlet is a measuring chamber through which the fluid is forced to flow on its way through the housing. In the measuring chamber, a nutating disc blocks the fluid`s clear path. As it flows through the measuring chamber, the fluid pushes the nutating disc to one side. It is the action of displacing the impediment which produces the wobble movement of the disc and circular motion of the nutating disc shaft. By means of a driver, a magnet with several poles is set into rotation, which is able to activate a magnetically switched contact through the lid of the housing. -
Page 9: Modular Flow Meter System Hdo
6. Modular Flow Meter System HDO The flow meters of series HDO are oval gear flow meters. This has proven to be a reliable and highly ac- curate method of measuring flow. Exceptional repeatability and high accuracy over a wide range of fluid viscosities and flow rates are features of the HDO series flow meter design. The low pressure drop and high pressure rating means the HDO series flow meter is suitable for both gravity and pump (in line) applications. For practically-orientated application, the flow meter system is made up of various modules: À Operating unit Electronic evaluating unit with touchscreen for operation of the flow meter. Á Protection cap Protects the modules basic flow meter, relay module or power supply unit when the operating unit is decentrally installed. Pulse converter Amplifies the signals from the basic flow meter. Is required if the signals need to be transmitted further than 5 m. -

Live mains connection! Electric shock can kill you. ► An operating unit or a protection cap must be mounted to the relay modules RM10, RM30 or to the power supply unit NG10 as protection against touching and contact with water. - Page 11 NOTICE The electromagnetic compatibility of the device is compatible with the emitted interference and interference immunity for residential and industrial areas. ► The system must not be operated in the immediate vicinity of strong electromagnetic fields (e.g. large motors, transformers) or interference sources that are connected to the mains (e.g. frequency converters).
