The reading is literally as simple as "pumping and storing". If an ID has questions, system pressure or
other elements setup they will be ignored for the simple reading. GPS coordinates are stored if available
along with a simple gas reading.
Note: A simple gas reading can be used as a mechanism to record a downloadable record of a gas
check. Consider establishing one or more ID's that are used to check gas mixtures. Take a simple gas
reading against these ID's and store the reading.
8.6 The GEM5000 as a Gas Extraction Monitor (GEM) gas flow
measurement screen
The GEM5000 gas extraction monitor enables gas and flow measurements to be recorded
by using:
 A flow device i.e. an Accu-Flo Wellhead, Pitot tube, Orifice plate, or User Input.
Refer to 5.7.3 Creating IDs for a full explanation of flow devices handled by
o
the GEM
 A temperature probe.
The GEM5000 instrument has the extra functionality to measure the calculated calorific
(energy) value of the gas. The field technician uses the information recorded by the
analyzer to make adjustments to the gas flow for specific wells. The initial and adjusted
flow rates are recorded.
Optionally, Questions and an additional System Pressure may be recorded as a part of
the reading workflow if setup in the ID.
Please note that when using select comments type of questions only 5 of the possible 8
comments can be displayed on the screen at a time. Additional comments may be
available. Scroll to them use of the scroll down
choosing IDs from the ID selection screen.

8.7 How to use a pitot tube (optional)

The GEM5000 gas analyzer enables the field technician to take gas measurements using
a pitot tube. The pitot tube is used for gas extraction systems and the pressure readings
are taken in mbar. Gas flow is calculated in the analyzer in SCFM (standard cubic feet
per minute) or in m
