Power Supply Requirements
The
MicroFlow-i
can operate from a DC supply of 10 to 28V. In all cases the unit
typically consumes 0.52W of power and will typically draw less than 22mA.
Cable Requirements
The
MicroFlow-i
comes with a fitted integral cable, if this cable is extended then
the total capacitance must not exceed the limits for the voltage applied, and the
hazardous area it is installed in.
The HART modem and PC or HART programmer are used to set up the
operation parameters for the
MicroFlow-i
sensor. The output can either be as a
4-20mA current giving flow velocity or as a digital signal via a HART master.
The
MicroFlow-i
cable is a twisted pair with an overall cable screen. The
twisted pair are red and black, connect the red to +ve and the black to the -ve.
The screen should go to signal ground.
Important Information
All shipping cartons should be opened carefully. When using a box cutter,
do not plunge the blade deeply into the box, as it could potentially cut or
scratch equipment components. Carefully remove equipment from each
carton, checking it against the packing list before discarding any packing
material. If there is any shortage or obvious shipping damage to the
equipment, report it immediately to Pulsar Process Measurement Limited.
Important Information
If the equipment is installed or used in a manner not specified in this
manual, then the protection provided by the equipment may be impaired.
