4.2
Installation
Generally, the installation arrangement is specified during the project planning phase,
before installation of the system. Nominal size, material and type of flange should there-
fore be in accordance with the design of the measurement facility. It is particularly
important that the meter inlet and outlet is of the same internal diameter as the adjacent
piping.
Fastening bolts, nuts and flange seals used must be suited to the operational conditions,
and comply with legal regulations and relevant standards.
4.2.1
Measuring location
General requirements:
●
The FLOWSIC600 can be installed in customary straight inlet and outlet pipes. The
adjacent pipes must have the same nominal size as the meter body. The internal
diameter can be obtained from the table (
) based on the flange rating
and the Standard. The max. permitted difference of the internal diameter of the inlet
pipe from that of the meter body is 3%. Any welding beads and burs on the flanges of
the inlet pipe shall be removed.
●
The meter body may be installed in a horizontal or vertical position. In case of horizontal
installation, the meter body shall be aligned so that the planes formed by the
measuring paths are in a horizontal position. This minimizes dirt in the pipeline from
entering the transducer ports. Vertical installation is only possible if the measuring
system is used for dry, non-condensing gases. The gas flow must be free from any
foreign material, dust and liquids. Otherwise, filters and traps shall be used.
●
Do not mount equipment or fittings which may adversely affect the gas flow directly
upstream the FLOWSIC600.
●
Seals at the flange connections between meter body and pipeline must not protrude
into the pipeline. Any protrusion into the flowing gas stream may change the flow profile
and thus the measuring accuracy may be adversely affected.
●
Pressure transmitter shall be connected to the pressure tap provided (
The pressure tap can be a 1/8, 1/4 or 1/2 inch NPT (female) port, depending on meter
size and customer requirements.
●
For the leak-proof connection on the pressure line, a suitable thread sealing agent (e.g.
PTFE tape) must be used when the pressure connection adapter is screwed in. After
Installation and Commissioning the leak-tightness must be checked. All leaks must be
repaired. Temperature probes shall be arranged as shown in
and
.
The installation requirements were evaluated according to the flow
disturbance sensitivity tests according to
●
OIML R 137-1&2, 2012 "Gas meters", Annex B and
●
ISO 17089-1, 2010, "Measurement of fluid flow in closed conduits -
ultrasonic meters for gas - Part 1: Meters for custody transfer and
allocation measurement.", 5.9.3 Installation requirements and flow profile
considerations.
Any deviation from the planned design of the FLOWSIC600 and installation
arrangement shall be agreed upon with the supplier and documented prior to
installing the meter.
