D625 Users Manual
INSTALLATION
Proper installation is crucial to the overall performance of the D625 Density Meter. The accuracy of
the meter can be adversely affected by improper installation.
To ensure meter accuracy it is imperative that the items listed below be considered prior to
installation of the meter into the system.
Also note that there must be some scheme present in the process flow system to induce sufficient
flow through the meter. Refer to the Process Connections section for more detail.
INSTALLATION PLANNING
Prior installation planning is critical for the best metering results. The table below outlines a
“checklist” of important items for proper installation planning.
PERFORMANCE - Installation Planning Checklist
All joints and couplings are airtight – GAS Bubbles in process fluid must be avoided
Meter is connected at a sufficient (> 5ft) distance from fluid pump
Pump (if applicable) is oriented so that it pushes fluid through the meter – NOT Pulls
Avoid vibration from surrounding equipment
Fluid should be at sufficient flow rate (> 1 GPM) with little or no cavitations as it enters the
meter
Avoid installing in an environment with quick and extreme temperature changes. ALWAYS
consider the use of an insulation jacket for OUTDOOR Installations.
Avoid mounting in direct sunlight or near surfaces with extremely high temperatures.
Refer to the meter dimensions prior to choosing a suitable location
SAFETY - Installation Planning Checklist
Ensure SAFE & PROPER handling of the meter during installation
Do NOT drop the meter or expose to extreme impacts
Adhere to all LOCAL electrical safety regulations
Only trained personnel should be allowed to install or maintain the meter
Verify that the process fluid is compatible with the wetted material of the density meter
