The Spirax Sarco oriface plate flowmetering system is available in a

number of options, at least one of which will suit the needs of a

customer. Options 1 to 4 are for simple systems where automatic

density compensation is not required. These are shown at the top of

the next column...simply tick the option that meets your needs.

Options for use with flowcomputers that DO NOT include density

compensation:

Options 5 to 10 include equipment that allows automatic density

compensation for maximum accuracy. These are shown

below...simply tick the option that meets your needs.

Customer Data Sheet

This customer data sheet is intended to gather together all

relevant information necessary to size and specify a Spirax Sarco

orifice plate flowmetering system. All equipment will be supplied

to the customer based on the information received.

Section C: Options available

Please complete all sections and supply drawings, sketches etc.

where appropriate.

Section A: Working fluid details

Notes: The pressure drop at specified maximum rate of flow will

be 24.9 kPa (100 inches water gauge) unless otherwise stated.

Below 25% of specified maximum rate of flow, system accuracy

cannot be guaranteed due to turndown limitations of orifice plates.

(BS 1042 / ISO 5167).

Section B: Pipeline details

Please provide a sketch showing all details of pipework including

any valves, bends, fittings etc. in the area where the M410 orifice

plate is to be fitted. This is important as the performance of all

orifice plates can be affected greatly by installation factors. Using

the information from sections A and B, Spirax Sarco will size the

correct orifice plate in line with the parameters laid down in

BS 1042 / ISO 5167.

Note: For all options, please state if a vent or drain hole is required

in the M410 orifice plate.

Section D: Associated equipment required

The M850 steam flow computer will provide automatic density

compensation for all steam flowmetering applications over the

range 100°C @ 0 bar g to 500°C @ 42 bar g.
