Installation Prior to installation of the flow sensor, the system should be flushed. Correct flow sensor position (inlet or outlet) appears from the front label of MULTICAL®. The flow direction is indicated by an arrow on the flow sensor. Please note: ULTRAFLOW® 54 may be lifted in the lifting rings only. Pressure stage ULTRAFLOW® 54: PN16, PS16/PN25, PS25. See marking on label. Temperature of medium, ULTRAFLOW® 54: 2…150 °C/ 2…130 °C/2…50 °C. See marking on label. Mechanical environment: M1 and M2 (fixed installation with minimum vibration and fixed installation with considerable or high vibration...

Straight inlet ULTRAFLOW® 54 ULTRAFLOW® 54 requires neither straight inlet nor outlet in order to fulfil the Measuring Instruments Directive (MID) 2014/32/EU and EN 1434:2015. Only in case of heavy flow disturbances before the meter will a straight inlet section be necessary. We recommend following the guidelines in CEN CR 13582. Operating pressure In order to prevent cavitation, the back pressure at ULTRAFLOW® 54 (the pressure at the flow sensor outlet) must be min. 1.5 bar at qp and min. 2.5 bar at qs. This applies to temperatures up to approx. 80 °C. Connection to calculator ULTRAFLOW® 54...

Connection to calculator ULTRAFLOW® 54 and MULTICAL®, galvanically separated If ULTRAFLOW® 54 and MULTICAL® are connected via output module (Y=2 or 3), ULTRAFLOW® 54 is galvanically separated from MULTICAL®. Maximum cable length depends on calculator. Note: Flow info cannot be read. Three-wire connection, MULTICAL® 602/603/801 via output module (Y=2 or 3). Two-wire connection, MULTICAL® 801 via output module (Y=2). Two-wire connection, MULTICAL® 602-D/603-G via output module (Y=2) and external 24 VDC supply. When using long signal cables, careful consideration is required in connection with installation....

Type number composition of separate ULTRAFLOW® 54 In addition to the basic variants output module (Y), supply module (Z) as well as meter factor (CC) and pulse duration (E) must be selected. The variant with galvanically coupled output module (Y=1) is solely for use together with MULTICAL®. The variant with galvanically separated output module (Y=2 or 3) is used in the following situations: A More than 10 m cable length between MULTICAL® and ULTRAFLOW® 54 is required (Y=2). B As flow sensor no. 2 in connection with MULTICAL®. If two flow sensors are used together with MULTICAL®, one must include...
