SECTION 4.0: START-UP

Each time an F-4000 ow meter is installed on a pipe, a new installation “site” must be created or

an existing site must be recalled from memory. An installation “site” contains all of the operating

parameters required to congure the meter for one specic installation. If it does not exist, it must be

created before the meter can measure ow.

ONICON F-4000 ow meters are normally shipped with the intended installation site pre-programmed

into the memory of the meter. This pre-programmed site was created and stored in the memory at the

ONICON factory and is based on installation data provided to ONICON when the meter was ordered.

The information programmed into the site is also provided in a document that accompanies the

installation hardware. It is titled, “Site Installation Details”.

If the information contained in the Site Installation Details document matches that specic installation

location, then the stored site can be recalled as per section 4.2 below. If there is any discrepancy, the

site must be edited and resaved before it is used. Contact ONICON for assistance in editing or creating

a new site.

Once a site has been recalled and loaded into active memory, the transducers can be activated by using

the “Install” function. During this process the meter will automatically select the optimum operating

frequency and establish a speed of sound reading for the uid in the pipe. Depending on the pipe

material and the operating mode (reect or direct) the meter may also adjust for any zero offsets and set

the level for the empty pipe detector.
