PRIME 4 Installation and Operation Manual
Installation 3
2 Installation
2.1 Overview
The PRIME 4 meter is a precision instrument and should be treated accordingly. Prior to installation, it
should be protected from adverse weather conditions and accidental abuse. Adequate pipe support must
be provided close to the meter because the meter is supported by the flanges. Piping must not produce an
undue strain on the meter. Dimensional outline drawings of the meter are available. See specifications
document SS01096 for dimensional outline drawings of the meter.
2.2 Preparing the Meter for Installation
Complete the following steps to prepare the PRIME 4 meter for installation:
• Flush the meter with a light lubricating oil if it has been left idle or stored.
• Use a carpenter's level on a flat surface of the meter housing to ensure the rotor is level (for example,
on the cover around the bolt circle or on the nameplate pad). This is important because the meter rotor
must not gravitate to one side.
• Ensure the drain plug is accessible, but the meter cannot be accidentally drained of product.
• Use a relief valve to protect the meter and system against the effects of thermal expansion.
• Install a deaerator or air eliminator, when necessary, to keep air and vapor out of the meter.
• Clean all piping internally before the meter is put into operation.
• Completely remove any rust, dirt, welding shot, and other foreign material from the meter.
• Remove the meter and install a spool piece if the system will be pressure-tested with water or if debris
will be flushed from the system.
• Protect the meter with at least a 40-mesh strainer, when necessary.
• Install a flow-limiting valve, when necessary, downstream of the meter to protect it from excessive flow
rates.
• Do not calibrate the meter with water or allow water to stand in the meter.
2.3 ATEX- and IECEx-Approved Installations
Standards used:
• IEC 60079-0 7th Edition, EN 60079-0:2018
WARNING: Thermal expansion of liquid in this equipment can cause high-pressure damage. A ther-
mal pressure relief valve may be necessary in the system.
