Flow meter control
This flow meter kit is specially designed for use
together with the reference machine FOM 71
LAB and complies with the new EN 60456/prA1.
The kit contains all necessary tubes and
connectors for installation to a water hose. If
installation to fixed tubes is preferred be sure that
a straight tube of 150 mm before and 75 mm
behind the flow meter is mounted in order to get
a uniform flow. The tube diameter shall be the
same as the attached tubes. Be sure that the
water has no particles that can block the rotating
sensor wheel in the flow meter. Mount if
necessary a filter in the water housing in front of
the straight tube. The kit also contains a standard
battery eliminator with euroconnection and 230V.
If other connections or voltages are needed an
eliminator should be bought locally with following
specifications: Output 24 VDC stabilised, Max
330mAmp, DC connector type: 2.1 mm pin,
negative pole in centre.
