• Viscous fluids

2.1 Installation of the meter

On installations which are required to comply with the European Union Pressure

Equipment Directive (PED) 2014/68/EU, it is the responsibility of the end user to ensure

that all Essential Safety Requirements of this directive are met.

The "PT" Meter has high resistance to shock while it is operating because of the supporting

effect of the fluid. This resistance is greatly reduced when the meter is out of the line or

inoperative.

CAUTION!

MECHANICAL EQUIPMENT DAMAGE

Great care should be taken to prevent shock.

Failure to handle the meter with care during installation, removal or shipment may result in

damage to the meter.

If sealing compound is used on piping during meter installation, use it sparingly to avoid

fouling meter parts. Absolute cleanliness of meter internals is important, and precautions

should be taken to prevent entry of foreign matter. Use a strainer upstream of the meter

tube section. Another common cause of meter malfunction, due to fouling of the rotor, is

objects left inside the pipeline.

CAUTION!

MECHANICAL EQUIPMENT DAMAGE

Flush and clean piping system prior to meter installation.

Failure to maintain absolute cleanliness of meter components may result in damage and

improper meter operation.

It is the responsibility of the end user to install the fitting in a well designed piping system

taking due regard of the following.

Installation and initial operation

Installation and maintenance instructions 9

• Internal/external pressure

• Ambient and operational temperatures

• Static pressure and mass of contents in operating and test conditions

• Traffic, wind and earth loading

• Reaction forces and moments which result from supports, attachments, piping, etc.

• Corrosion, erosion, fatigue, etc.

• Decomposition of unstable fluids

• Possible damage from external fire

2.2 Daniel Method of aligning meter tube flange to

"PT" Meter flange

Internal alignment throughout the metering section is vital to prevent offsets, steps or

gasket protrusion within the bore which could cause disturbance to the flow pattern.

Alignment is accomplished by dowel-pinning.

On all Daniel raised face flanged "PT" Meters and "PT" Meter Tubes three knock-out dowel

pin holes are drilled in each flange for alignment of the bore of the meter to the bore of the

meter tube.

On ANSI Class 150 lb. and 300 lb. meters and meter tubes where the dowel pin holes are

located tangent to the raised face, female face-type gaskets are used.

On ANSI Class 400 lb. through 2500 lb. meters and meter tubes where the dowel pin holes

are located beyond the inner bolt circle, series-type gaskets are used.

Care should be taken not to allow the gasket to protrude into the flow stream upon

installation.

It is recommended that dowel pins be removed after flange bolt-up and grease packed in

the holes to prevent rust.

2.3 Meter tubes

Experience has confirmed the necessity of adequate upstream and downstream straight

pipe adjacent to the meter. Daniel

™

"PT" Meter Tubes and straightening vanes are

fabricated to proper dimensions and tolerances to assure that the flow pattern through

the meter is undisturbed by piping configuration.

The table of recommended dimensions for "PT" Meter Tubes takes into account piping

design, where swirls and disturbances are introduced by fittings, valves, etc., adjacent to

the meter tube section. The recommended lengths shown (with a straightening vane) are

for the maximum flow disturbance conditions. The illustrations show proper positioning of

straightening vanes.
