Installation
Note
Installation must be carried out in accordance with local site
requirements and regulations.

Copies of referenced drawings are located in the drawing appendix.
The recommended orientation of the density meter is vertical with
upward flow. Mounting the density meter vertically allows for usage at zero
flow, avoiding problems caused by vapor that can become trapped in the
density meter at low flows.
Mounting the density meter horizontally is acceptable if the flow is greater
than 5 L/min. This is to avoid trapping gas bubbles that cause unsteady
density measurements.
Note
For clarity, the horizontal installation drawing shows bypass systems
above the pipeline, but in practice, the bypass system is best installed to one
side of the main pipeline.

In addition to mounting orientation, the following must be considered
prior to installation.

Dimensions: Refer to the dimensional drawing in the drawing
appendix.

Pressure: Place flow restrictors, flow control valves, or pressure control
valves downstream of the density meter in order to maintain full line
pressure in the sensor. This will prevent gas bubbles from forming in
the liquid due to a pressure drop occurring upstream of the instrument.

Support: The weight of the density meter is carried by the adjoining
pipework, which should be supported and correctly aligned to
minimize mechanical loads, such as twisting.

Heat tracing: Where the density meter is to be installed in a system that
requires heat tracing, insulation of the density meter may be required.
