trigger explosions in hazardous areas. The risk assessment requires an emptying
and ventilation of the pipeline for connection with installation and removal of a turbine. Then and only then is it assured that there is not an hazardous gas mixture in
the pipeline. Naturally, work must only be carried out by trained personnel (see chap-
ter 1.2.4.4 Qualification of personnel), who are also trained to recognize suitable tools
and use them exclusively. The risks were summarized alongside development and
measures were taken to minimize these risks.
Measures for risk minimization:
-
All pressurized parts are designed in accordance with AD 2000 rules and regulations, Pressure Equipment Directive, Annex 1
-
The complete pressure design has been inspected by TÜV Hessen
-

Overview of versions
1.3.1.
Description
The TME400-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 Wiegand or Reed sensor element and then added together in internal archives. The result is registered in an electronic meter.
There are a high-frequency (HF) and a low-frequency (LF) output, where the HF output is preferably used as a flow sensor for control tasks and remote transmission. In
addition to these outputs, the TME400 VM has a serial RS 485 interface for digital
data readings and parameterization. The TME400-VM is used in non-custody-
transfer applications.
The TME400-VMF (MID) is the turbine meter for custody-transfer applications and
has an equivalent function and operating method to the TME400-VM. The essential
difference is the 2-channel measuring head version. It is used in custody-transfer
applications.

Power supply
Battery-operated device
The TME400 is equipped with a replaceable 3.6 V lithium battery. The device is designed for continuous operation for approximately 10 years. To achieve this, the devices must not be read more than once weekly and/or woken with the external button.
Battery-operated device with additional external power supply
An electric supply of the TME400 via the 4-20mA current loop reduces the power
consumption from the batterie and typically extends the service life of the battery to
more than 12 years.
If the TME400 is additionally electrical powered by the RS485 interface, the service
life of the battery is typically extended to more than 12 years.
Battery replacement indicator
The remaining battery life is determined by means of an internal calculation. An indicator in the display appears when it is time to replace the battery. Battery replacement is described in chapter 3.1.4 Battery replacement. In parameter G20 Date of
last battery change the date of the last battery change is displayed (see chapter 4.3.3
Coordinates in context).

Areas of application
The following chapter provides handling instructions for the TME400 turbine meter for
the purpose of safe and reliable operation of the device.
Note
Some of the settings described below must not be made until you have read
the explanations in chapter4 Operation.
1.4.1.
Working principle of the TME400
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
min
- Q
max
) is approximately proportional to the
mean gas velocity and thus the flow rate. The number of rotations, therefore, is a
measurement for the gas volume flowing through.

Figure 1: Turbine meter sectional drawing
There is a permanent magnet on the end disc of the turbine shaft which induces a
voltage pulse in the Wiegand sensor with every rotation. This pulse is supplied to the
measuring unit of the meter head, which detects the operating volume flow directly as
a main totalizer and determines the gas volume flowing through the meter by adding
up the pulses and division by the meter factor (number of pulses per m3). This operating volume is shown in the display of the TME400.

Note
The unchanged signal frequency of the sensor element is output at the
HF output.
The LF output transmits this HF frequency with a variable scaling factor (chapter
4.3.3.1 Volume / Meters).
1.4.2.
Integrating the turbine meter into the pipeline
Turbine meters from RMG are equipped with connecting flanges. For a secure connection, the connection dimensions of the flanges of the pipelines to be connected
must match the connection dimensions of the flanges of the device.
• ANSI pressure levels: flange connection dimensions correspond to the
standard ASME B 16.5.
• DIN pressure levels: flange connection dimensions correspond to the
standard DIN EN 1092.

Note
When flange seals which protrude into the pipeline are used for turbine meters, the measuring accuracy can be influenced negatively. Ensure that the
flange seals do not protrude beyond the seal surfaces into the pipeline.
Danger
Gas escape due to incorrect seal
If incorrect flange seals are used for the assembly of turbines, an explosive
gas mixture can form due to leaks.
Danger of poisoning and explosion!
In addition, the stress on the flange is increased to an impermissible level
when tightening the thread bolts.
Ensure secure fastening/attachment of the TME400 during assembly in order
to avoid crushing. Ensure that you keep your fingers (or other body parts)
away from these openings and gaps when pulling the flanges together.

Installation
Note
Installations disturbing the gas flow directly upstream of the turbine meter
must be avoided
(see DVGW guideline G 492 II and PTGB guideline G 13).
An inlet pipe of at least 2 x DN is required upstream from the turbine meter TME400.
The inlet pipe must be designed as a straight pipe section with the same nominal diameter as the meter. With heavy upstream pertubations, installation of straighteners
is recommended (refer to the table on the next page). A pipe or bend with the nominal diameter of the meter having a total length of 2 x DN must be arranged downstream from the meter.
Temperature measuring devices must be installed at a distance of at least 1 x DN or
at least 300 mm with nominal diameters DN 300.
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.
Recommended installation with straightener Perforated plate straightener LP 35
1 Perforated plate straightener
•
The opening angle of the reducing or expansion pieces which are installed upstream from the TME400 turbine meter must not be more than 30°.
Note
A screen must be installed on the inlet side of the meter for protection of
the turbine meter from foreign objects which may be present in
the gas flow. The screen can be, for example, a perforated plate/filter of
0.15 mm (available as an accessory).
1 Introduction
Manual TME400-VMF · EN02 · 2018 September 6th
26
Danger
Protect the turbine meter from damage caused by high pressure changes
fluctuations in the flow, e.g. if the downstream pipeline system is filled or
blown off.
Danger
Welding on the line must only take place at a safe distance from the meter.
Extreme temperatures in the line near the meter can cause permanent damage to the meter.
Danger
Establish all electrical connections between meters and amplifiers or flow
computers as specified in the installation manual. Ensure that the connections are intrinsically safe.
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.
1.4.2.5.
Threshold values
The following threshold values are recommended for maximum durability and the
highest measuring accuracy:
1 Introduction
Manual TME400-VMF · EN02 · 2018 September 6th
27
Note
Maximum overload
< 20% above Qmax, short-term
(< 30 sec)
Maximum flow rate changes and/or
impact loads
< 0.01·Qmax/sec
=
1% of Qmax/sec
e.g. start-up 0 - 100%: > 100 sec
Maximum pressure change:
< 0.1 bar/sec
Maximum flow pulsation:
< 5%
Particle size in the gas flow:
< 5 µm
Lubrication:
Refer to lubrication chapter
Intervals depend on the status of the
gas (condensate, rust, dust)
Vibration / mech. vibration:
< 1 mm/sec (vibration speed)
These measures must be determined and checked during commissioning, before
filling, during the start-up and run-in phase of the meter and evaluated, in particularly
with simultaneous occurrence of multiple of these threshold values. Intervention in
the system for improvement of measuring conditions must be carried out when the
aforementioned threshold values are reached.
Note
The operator should record the overall measurement data (meter and operating data) during the entire operation in order to be able to recognize causes
of potential damage at an early stage and to intervene in good time.
Remedy and/or relief of critical operating statuses can be achieved, for
example, with the following measures:
•
Start-up screen (MW < 0.15 mm)
•
Filter
•
Meter protection perforated plates (Ø 3 - 4 mm)
•
Valves with control drive (flow change)
•
Check valves (pulsation, backflow)

Putting the device into operation
Note
You receive the TME400 parameterized and calibrated according to your
specifications, so that no additionally settings are generally required.
However, check whether these settings match your specifications; check the settings
of the pulse width, the frequency reducer and the settings of the current output (for
versions with current output).
Bring all totalizers to the meter status which you desire. (see chapter 4.2 Program-
ming).
Note
Parameters can be changed exclusively with the device open.
1.4.2.12.
Maintenance / lubrication
The TME400 is equipped with permanently lubricated bearings up to a nominal
diameter of DN150 as standard. Nominal diameters of DN200 or higher are provided
with an integrated lubricating device. Optionally, the TME400 can also be equipped
with the "small oil pump" lubricating devices for DN25 to DN150 versions.
The type of lubricating device and the lubricant requirement depend on the nominal
diameter and the pressure level:

Figure 4: Connection assignment of the TME400
Note
Generally, no electrical connections are necessary when the turbine meter is used strictly as a flow indicator.
However, as shown in Figure 4: Connection assignment of the TME400 configurations are possible. If the TME400 is used as a "flow rate sensor", an electrical current
must be connected to 4..20 mA (X9). The TME400 "sensor is passive, power supplied and limits the current to the appropriate value. With this application, the current
feed is used as an additional supply. (see chapter 1.3.3 Power supply). This power
supply must be electrically isolated.
If digital communication with the TME400 is desired, it can be connected to the
RS485. The differential signals are available via A and B with RS485 (X6). Please
also look out for crossed signal lines and change the connections as necessary. In
the process, the TME400 can also be fed with 6-30 VDC via "+ Uext" and "- Uext" in

addition to the internal battery (non-Ex zone). This can take place independently or in
combination with the RS485 interface.
Terminal block X6 also contains a digital input K1, which can be used to start, stop
and reset the totalizer.
Caution
In the Ex version, refer to the EC type approval certificate for the maximum
values for the current output and the RS 485!
Meter pulses from a transmitter – proportional to the flow rate – with 2 frequency outputs can be read via "Pulse In" (X5) (main transmitter and second, redundant transmitter). This is necessary, in particular, for TME400-VMF variants for custody-transfer
applications.
Meter pulses and redundant meter pulses can be output via "Pulse Out2" (X3). An
alarm output can also be connected here.
Use the wire end ferrules for the connecting cable and route them in from below; a
seal holds the cable. To be able to pull a cable out again, press the small white
square (marked with the X) down using a small screwdriver (at the bottom in
Figure 3: Electronics with cover and Figure 4: Connection assignment of the
TME400; top of the plug strip) in order to open the locking device. Hold down the
square and pull the cable out of the connector strip.

Caution
It is necessary to remove the seals, particularly the seal over the calibration
button in order to press the calibration button (see Figure 7: Position of the
calibration button).
The TME400 must only be used for custody transfer with unbroken seal. Removal or damage to seals normally entails considerable expenses!
Re-application of seals must only be carried out by an officially recognized
inspection authority or calibration officials!
The principle of the programming is shown based on the example of changing the
output pulse factor:
I. Move with the arrows ( ) to the position: A11
II. Activate the calibration button (see Figure 7: Position of the calibration button)
III. The blinking "INPUT" text appears above the displayed value in the display
view.
IV. Press for more than 2 seconds
V. The value begins to blink at a position
VI. With the and arrows, you can now increase or decrease the value at
this position. For the values, after the "0", you also have "-1" available in order
to enter negative values, if necessary.
VII. With the and arrows, you can move to a different position of the val-
ue and change it – as described in the point above.
VIII. An additional position is added when you move with the and before
the displayed number.
For example, only the units digit is displayed. If you move in front of it, you will
also have the tens position available as an entry.
IX. By pressing and holding the "right" button , the position of the decimal
point is changed. After pressing and holding, the decimal point is inserted after
the blinking digit.
X. By pressing and holding the "left" button , the entry can be canceled. If a
change and/or entry is necessary, the entry must be restarted.
XI. When you have finished making an entry, you confirm it by briefly pressing
.
XII. A plausibility check takes place and the result is displayed immediately.

XIII. If this check shows an implausible entry, "rAnGE" will be shown briefly in the
display and the display jumps back to the original value.
XIV. If this check shows a plausible entry, "Good" will be shown briefly in the dis-
play and the value is adopted as a new value.
XV. Now you can – if necessary – change other parameters.
XVI. After about 1 minute without additional entries, the display returns to the dis-
play of the main meter.
XVII. By pressing the calibration, you close the further entry of custody-transfer pa-
rameters.
XVIII. After another minute without an entry, the change possibility is closed auto-
matically.
Note
Some of the coordinates permit other settings as purely numerical values.
However, these other entries are assigned numbers so that the adjustment
can be carried out as described.
Example:
Current mode F02 can be deactivated or activated on various settings. This is adjust-
ed as follows:
0 Off (default)
1 No errors
2 Error 3.5 mA
3 Error 21.8 mA
4 0 - 20mA
If F02 = "0" is selected for the coordinate, the current output is switched off.
Note
With some coordinates, a number is assigned fixed values. Instead of an
adjustment with 0, 1, ..., these numerical values are shown directly. Changes
are possible with the arrows and , then the next higher or
lower value is shown and can be adopted with .

Z04
X:Y maximum pulse
error
A differential circuit compares the metered pulse of measuring and
comparison channels alternatingly. Every deviation is counted internally. An alarm is generated if the adjusted limit value is exceeded.
The failure counter is reset to 0 for each new measurement or after
the maximum number of pulses (Z05) is reached.

Z26
Characteristic correction
If the TME400 is supplied with a current supply, the TME400 enables a characteristic correction via a polynomial. This correction
must be activated with coordinate Z26. With this polynomial correction, the corresponding percentage deviations of the turbine meter

from a reference standard are determined for fixed percentage flow
rate values. From these deviations, a polynomial function which ideally reflects the curve running through these points is calculated. The
coefficients of the polynomial A-2, A-1, A0, A1 and A2 are adjusted
by the manufacturer in the coordinates B10 to B14 or can be entered
there when the manufacturer of the turbine meter provides these
values.

Cable
Signal cables (LF output, HF output, current loop connection, control input) must
have 2 or more wires twisted in pairs and shielded (LiYCY-TP).
2-wire, twisted and shielded cables (LiYCY-TP) must be used for the data cables
(RS-485).
The shielding must be grounded on both ends - on the TME400, as described in the
section 5.1.5 Cable connection.
Cable cross-sections of 0.5 mm² are recommended. Due to the cable screw connection, the outer diameter of the cable must be between 4.5 and 6.5 mm.
Caution
The maximum cable length is limited when used in hazardous areas due to
the limit values for intrinsically safe current circuits and depending on the
inductivity and capacity of the cable.
5.1.5.
Cable connection
Connect the shield on both ends to the cable screw connections on the outside of the
housing, as shown in the figure below:
• Unscrew the union nut.
• Pull the terminal insert out of the plastic.
• Slide the cable end through the union nut and the terminal insert and bend the
shielding back.
• Plug the terminal insert back into the connecting piece.
• Tighten the union nut.
• Every Ex signal circuit must be routed with a dedicated cable which must be guid-
ed through the appropriate PG screw coupling.

- A maximum of 125 registers can be read or written (in one command)..
- Text fields must have at least one terminating zero (0x00).
- Writing of certain parameters causes internal initialization of the hardware and/or:
- Deletion of intermediate results (pulse output, meter calculation, etc.).
- Therefore, the parameters should only be overwritten as necessary
(e.g. meter factor)
- Meter statuses are delivered as a unit32 value (without decimal)
