Local Mounted Enclosure (LME)
The LME consists of an electrical enclosure and a solid cover made of stainless steel. This
configuration contains a mounting bracket and a preamplifier which works with two
standard pickoff coils mounted into the meter housing.
The electrical enclosure contains an external and an internal grounding lug. The two
enclosure openings are plugged with stainless steel plugs. Refer to
Chapter 2 for more
specifications.
LME - High temperature
The LME - High temperature consists of an electrical enclosure and a solid cover both made
of stainless steel. This configuration contains one mounting bracket and two high
temperature terminal blocks which are the connections between the high temperature
pickoff coils and the flex cable.
Important
The customer provides and installs a flex cable.
The flex cable is the connection between the preamplifier that is assembled into a Remote
Mounted Enclosure (RME), not more than 6 meters from the center of the meter housing
to the center of the RME.
The electrical enclosure contains an external and an internal grounding lug. The two
enclosure openings are plugged. Refer to
Chapter 2 .
Remote Mounted Enclosure (RME)
The RME is an electric transmitting device used primarily in the petroleum industry for
remote installation of liquid turbine meter electronics. The RME is specifically designed for
high temperature applications.
The turbine meter is ideal for applications requiring high frequency resolution.
Applications may include electronic registers or flow computers.
1.2.2 Operation overview of the turbine meter
Metering systems combine turbine meters and electronic instrumentation to measure
volumetric total flow and/or flow rate. Metering systems are used to provide
measurement information in fluid transport, petroleum and chemical processing, custody
transfer of liquids, blending systems, in product batching and in field or plant operations.
• Each turbine meter is comprised of a cylindrical housing that contains a precise
turbine rotor assembly. The magnetic pickoffs are mounted in a boss on the turbine
meter body.
• As fluid passes through the turbine meter, it causes the rotor to revolve with an
angular velocity proportional to flow.
