  • Page 20: Overview Of Versions

    1.3.1 Description The TME 400-VM is a turbine meter which is used for volume measurement of the operating volume of non-aggressive gases and burnable gas. The operating volume flow is determined based on the turbine speed, which is scanned by means of a Wie- gand or Reed sensor element and then added together in internal archives.

  • Page 21: Firmware

    The currently delivered devices have either firmware version 1.12 or 11.12 installed, depending on the components used in the index head. With the devices of the type TME 400-VM(F) there is no functional difference between the two versions. The in- stalled version is shown in coordinate G02.

  • Page 22: Area Of Application

    1.3.5.1 Installation and mounting position The TME 400-VM and TME 400-VMF can be supplied with DIN and ANSI connec- tions. Up to nominal diameter DN 200, the installation position of the turbine meter with permanent lubrication can be selected as required. From nominal diameter DN 250, the meter must be installed in the ordered installation position.

  • Page 24: Areas Of Application

    Not custody transfer measurements are of course possible in natural gases with a hy- drogen content above 10 mol%. However, a reduced measuring range must be taken into account if applicable. Please contact RMG for further information. 1.4 Areas of application The following chapter provides handling instructions for the TME 400 turbine meter for the purpose of safe and reliable operation of the device.

  • Page 25: Working Principle Of The Tme 400

    1 Introduction 1.4.1 Working principle of the TME 400 The working principle of a mechanical turbine meter is based on the measurement of the gas velocity of the flowing gas which powers a turbine wheel. The speed of the turbine within the measuring range (Q ) is approximately proportional to the mean gas velocity and thus the flow rate.

  • Page 26: Integrating The Turbine Meter Into The Pipeline

    1.4.2 Integrating the turbine meter into the pipeline Turbine meters from RMG are equipped with connecting flanges. For a secure con- nection, the connection dimensions of the flanges of the pipelines to be connected must match the connection dimensions of the flanges of the device.

Danger of poisoning and explosion! In addition, the stress on the flange is increased to an impermissible level when tightening the thread bolts.
  • Page 30 If there is pertubation (e.g. a gas pressure control device) upstream from the inlet pipe, a perforated plate straightener is also necessary. Perforated plate straightener according to ISO 5167-1 or the type RMG LP-35, which cause a pressure loss by a factor of 2.5 in comparison with the standard straightener, can be used.
  • Page 31 1 Introduction Perforated plate straightener The opening angle of the reducing or expansion pieces which are installed up- • stream from the TME 400 turbine meter must not be more than 30°. Note If necessary, a screen must be installed before the inlet pipe of the meter for protection of the turbine meter from foreign objects which may be present in the gas flow.
  • Page 32 1 Introduction Caution Liquids remaining in the line after hydrostatic testing can damage internal parts of the meter. If hydrostatic testing is not possible, the turbine meter must be replaced with a pipe section. Ensure that there is no liquid remaining in the line above the meter after the hydrostatic testing.

  • Page 36 1 Introduction 1.4.2.8 Measuring ranges Type TME 400 turbine meters have measuring ranges of at least 1:20 at atmospheric pressure (see chapter 1.4.2.9 Measuring accuracy). At a higher pressure, the meas- uring range can be expanded to 1:50. The measuring ranges are between 2.5 and 25,000 m /h (operating conditions), depending on meter size.
  • Page 37 1 Introduction According to DIN30690-1, the maximum operating pressure for non-flammable gases may not exceed 16 bar; for flammable gases, EN746-2 defines a maximum pressure of 5 bar for DN25 and 2 bar for DN40. Usually these pressure restrictions are speci- fied on a plate on the pipe fittings.
