Appendix A. Measurement Considerations

There are a variety of environmental and installation factors that can affect
measurements. These factors should be discussed with a GE applications
engineer or field sales person by the time you receive the PM880. However,
if you decide to add additional measurement sites, this section contains
some basic guidelines for selecting a measurement site and constructing a
sample system. This section includes the following:

•

Choosing a Measurement Site - see below

•

Moisture/Temperature Probe Considerations - page A-176

•

Sample System Guidelines - page A-179

A.1 Choosing a Measurement Site

You should have discussed environmental and installation factors with a GE
applications engineer or field sales person by the time you receive the
PM880. The equipment should be suited to the application and installation
site.

•

Choose an installation site for the probes and sample systems that is as
close to the process line as possible. Avoid long lengths of connecting
tubing. If long distances are unavoidable, a fast sampling by-pass loop is
recommended. Do not install any other components, such as filters,
ahead of the probes or sample system unless instructed to do so by GE.

•

Observe all normal safety precautions. Use the probes within their
maximum pressure and temperature ratings.

•

Locate the electronics unit away from high temperatures, strong
electrical transients, mechanical vibrations, corrosive atmospheres, and
any other conditions that could damage or interfere with the meter
operation.
