MTS Qantometer
Keep this manual easily accessible for
all users.
Please respect all national rules for in-
stallation, operation and service of gas
meters.

1 Installation

Dimensions and weights:
see Annex 1
Recommended installation:
see Annex 2
• MTS meters are designed for use
with compressed air, clean and non
aggressive gases.
• The maximum admissible operating
pressure of the MTS is 16 bar.
• MTS meters can be installed hori-
zontally or vertically.
• Check that the direction of the flow is
in accordance with the arrow printed
on the meter body.
• To guarantee perfect positioning of
the MTS60 between ISO PN10-16
flanges, use the centering sleeves
delivered with the meter.
• Check visually that the meter has not
been damaged during transport. (1)
• No welding is allowed with meter in-
stalled. (2)
• Flanges must be parallel to guaran-
tee a tension free mounting. Maxi-
mum tightening torque of the bolts:
120Nm. (3)
• 6 DN straight inlet pipe and 4 DN
straight outlet pipe minimum recom-
mended. (4)

• A strainer with a mesh ≤100 µm is re-
commended to avoid damaging the
turbine wheel. (5)
• To prevent damage the turbine
wheel, prevent pressure pulses and
excessive flow rates. (6)
• Don't install the meter at a low point
in the network, to prevent conden-
sate build-up. (7)
• Use of inlet, outlet valves and drain
valve is recommended to allow easy
start up, shut down or servicing on
the installation. (8)

2 Start-up

Ensure that the pipe upstream of the
meter is free of particles.
• Close the downstream valve.
• Open slowly the up stream valve. Li-
mit the change of pressure to 0,3
bar/second maximum.
• Check the gas tightness of the me-
ter flanges.
• Open slowly the downstream valve,
ensuring that the flow doesn't ex-
ceed the maximum flow of the meter.
• Check the tightness of the complete
installation.

3 Shut down

• Close slowly the downstream valve
and check that the meter is no lon-
ger recording.
• Close the upstream valve.
• Open slowly the draining valve up to
the complete depressurisation. The
change of pressure should not ex-
ceed 0,3 bar per second. Some gas
may still be inside the meter and the
