INSTALLATION AND REMOVAL
3.3.1
MATERIALS REQUIRED FOR INSTALLATION
3.3.1.1 Insertion
Tool
The insertion tool is not provided with the e-FlowMeter.
The insertion tool is needed for the installation and removal of the e-FlowMeter in a CLA-VAL valve. It allows the rotation of
the measurement cylinder in the right position.
The insertion tool with a length of 165 mm is used for e-FlowMeter sizes 1,2a and 2b, the insertion tool with a length of
368 mm is used for e-FlowMeter sizes 3 and 4.
3.3.1.2
Power supply for pulse and digital pulse output
There are 2 ways to power the e-FlowMeter for the pulse output. The first is 5 VDC, the second is 6-24 VDC with stabilized
power supply, battery, turbine e-Power MP or IP. 3 mA minimum are required (see schematic chapter 3.3.4).
3.3.1.3
Power supply for 4-20 mA output
The voltage needed is 8 - 32 VDC, 20 mA minimum are required. Take care that the loop is closed to obtain a signal
4-20 mA.
3.3.1.4 Cabling
The e-FlowMeter has a 3 or 10 meter cable with 12 wires of 0.22 mm
2
supplied and attached as a factory standard. If
additional lengths of cable are needed, the connections should be made with 0.22 mm
2
or larger wire and may need to be
shielded in some environments where high electrical noise may exist. If using shielded cable, one end of the shielding
should be connected to an earth, such as piping system fitting, etc.
