Electrical Installation
All wiring connections should be made with good quality shielded instrument cable; wiring
between terminals which are inside the instrument enclosure, or between a flowmeter and an
integrally mounted instrument may use non-shielded wire. Cable shields or drain wires should
be connected to the instrument ground (GND) at the instrument end only – isolate the
shield/drain wire at the flowmeter end of the cable.
The terminal connections on the instrument will allow for usage of wiring up to 1.5mm

cross
section (16AWG) – if two wiring connections into the same terminal are required the maximum
cross section of each wire is 0.75mm

. Wire insulation should be stripped to a length of 6.5mm
and conductors should be fitted to the terminals so that there is minimal exposed conductor.
Terminals can be tightened with a 2.5mm or 3/32” flat blade screw-driver.

Input Connections
The EB11 can take a variety of common industrial inputs, including coil, NPN and reed. A 8.2V
DC power supply terminal with current capacity of 10mA is available for powering low-power
flowmeter electronics. This is available at terminal 4.
4.1.1
Sine-wave signal (coil input)
The EB11 is suitable for use with flowmeters with a coil output, such as the FLOMEC TP
series turbines, or the Weigand sensor on the FLOMEC DP Insertion meters. The minimum
sensitivity level is 30mVpp. Note, 2 wire coil sensors are not polarity sensitive.
