Flow Devices 

The BIOGAS 5000 gas analyzer enables flow measurements to be recorded by using 

either: 
 

 

A pitot tube 

 

Orifice plate 

 

An anemometer 

 

8.5 

How to use an anemometer (optional) 

 

 

 

 

The BIOGAS 5000 gas analyzer has the facility to attach an anemometer device enabling 

the site engineer to measure the flow of gas within an extraction system.  The 
anemometer can be set to display two values; m/s (meters per second) and m

3

/hr 

(metres cubed per hour). 
 

It is best practice to take the gas reading first before taking the flow reading with the 
anemometer attached. 
 

If using a ‘borehole ID’ the internal pipe diameter can be predetermined in the optional 
LSGAM software.  Once set, the site engineer cannot edit the pipe diameter setting. 

 
If the site engineer is not using a borehole ID or the pipe diameter is not set in LSGAM 

the operator will be prompted to enter a pipe diameter with a new ID on the analyzer.  
Select soft-key ‘Next ID’ from the Main Gas Read screen, followed by soft-key ‘Add’ and 

add a new borehole location.

 

  
In order to use the anemometer it is important to know the internal diameter (ID) of the 

pipe if you want to calculate the flow in m

3

/hr (metres cubed per hour).  This must be 

the internal diameter not the outer diameter (OD) i.e. pipe outer diameter minus twice 

the pipe wall thickness.
