The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing is required.
An optimum location is defined as:
A piping system that is completely full of liquid when measurements are being taken.
The pipe may become completely empty during a process cycle – which will result in an error code being displayed on the flow meter while the pipe is empty. Error codes will clear automatically once the pipe refills with liquid. It is not recommended to mount the transducers in an area where the pipe may become partially filled. Partially filled pipes will cause erroneous and unpredictable operation of the meter.
A piping system that contains lengths of straight pipe such as those described in Table
2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation. The straight runs in Table 2.1 apply to liquid velocities that are nominally 7 FPS [2.2 MPS]. As liquid velocity increases above this nominal rate, the requirement for straight pipe increases proportionally.
Mount the transducers in an area where they will not be inadvertently bumped or disturbed during normal operation.
Avoid installations on downward flowing pipes unless adequate downstream head pressure is present to overcome cavitations in the pipe.
