TECHNICAL DESCRIPTION

ULTRAFLOW

54 DN150-250

5512-876 GB/04-2012/Rev. F1

7.3

Straight inlet

ULTRAFLOW

®

54 requires neither straight inlet nor outlet in order to fulfil the Measuring Instruments Directive

(MID) 2004/22/EC and EN 1434:2007. A straight inlet section will only be necessary in case of heavy flow
disturbances before the meter. We recommend following the guidelines of CEN CR 13582.

Optimal position can be obtained by taking the below-mentioned installation methods into consideration:

Figure 11

For general information concerning installation see CEN report

DS/CEN/CR 13582, Heat meter installation.

Instructions in selection, installation and use of heat meters

.

7.4

Operating pressure

In order to prevent cavitation the back pressure at ULTRAFLOW

®

54 must be min. 1.5 bar at q

p

and min. 2.5 bar at

q

s

. This applies to temperatures up to approx. 80°C.

For further information on operating pressure see

paragraph 8.7

A

Recommended flow sensor position

B

Recommended flow sensor position

C

Unacceptable position due to risk of

air build-up

D

Acceptable in closed systems.

      Unacceptable position in open systems
      due to risk of air build-up in the
      system.

E

A flow sensor should not be placed

      immediately after a valve, except for
      block valves (ball valve type),
      which must be fully open when not
      used for blocking

F

A flow sensor must never be placed

on the inlet side of a pump

G

A flow sensor should not be placed after

a two-level double bend
