30 Storage
Section 2: Installation Owner and operator manual
January 2015 3-9008-001 Rev M
When assembling a flow measurement system that will contain a Daniel Senior Orifice Fitting,
particular attention should be paid to the requirements for permanent joining of components.
This will be to ensure optimal measurement performance and successful pressure test results.
Referencing an appropriate measurement code (AGA-3, ISO 5167, etc.) will aid in this assembly.
2.2 Storage
Follow your company’s equipment procedures when storing measurement equipment. A light
spray of rust inhibitor applied to the inside bore of a Senior and to the bore of the meter tube
may aid in protecting its surface finish during storage.
2.3 Preliminary steps
The Senior may arrive at your site in one of two ways, as a component in a meter tube assembly
or as a loose fitting. If it is received without a meter tube attached, see the appropriate code
(AGA-3, etc.) for meter tube requirements.
It is the responsibility of the product operators to clean the Senior and all piping components of
foreign matter such as welding debris, scale, oil, grease, and dirt before commissioning.
Record the serial plate data on the Senior for future reference. Always provide the serial number
and model number when ordering spare parts. The factory packages orifice plates and seal rings
separately from the Senior.
Follow all the safety and equipment limits recommended in Section 1.2.1: Technical data of this
manual. It is the owner’s and/or purchaser’s responsibility to comply with these parameters.
On installations which require compliance with the European Union Pressure Equipment
Directive (PED) 97/23/EC, it is the responsibility of the end user to ensure that all essential safety
requirements of the directive are met.
Particular attention should be paid to the requirements for permanent joining and non-
destructive testing. Refer to the “Daniel Orifice Fittings - Installation and Operating Instructions
specific to the Pressure Equipment Directive”, Part Number 3-9008-002.
Follow all the safety and equipment limits recommended on Section 1.2.1: Technical data of this
manual. It is the owner’s and/or purchaser’s responsibility to comply with these parameters.
