Installing the Sensor
•
The sensor is supplied with a 1” BSP to M20 thread adapter. The Sensor
housing is designed to accept a 1” BSP female threaded coupler for pipe or
conduit.
•
Ensure that the sensor is positioned at a 45° angle to the surface of the
measured application, as this will achieve the best results. An example of
this is shown in the diagram below:
•
When using one of the Pulsar Angled Mounting Brackets, secure the bracket
using the correct size screws/bolts/U-bolts (12mm diameter thread).
•
Tighten the sensor into the bend, and then screw the thread adapter onto the
bracket using the nut supplied.
CAUTION: extreme over-tightening may
crack or cause damage to the unit or bracket.
•
Position the sensor so the green ‘dot’ that is shown on the label between the
two green arrows is on the top of the device, and is central to the movement
of flow in the channel.
•
If desired, the sensor cable may be extended up to a maximum of 1000m.
Install the sensor cables in grounded metal conduit. Do not run in cable trays
or duct banks with variable frequency drives or other high voltage sources.
•
When extending cable for a MicroFlow-i sensor, ensure that all wiring in any
junction /connector boxes are correct.
•
Attention should also be taken, when mounting the unit, to ensure that strong
windy conditions are avoided wherever possible to prevent abnormal
operation.
•
The sensor can be positioned to obtain readings following the direction of the
flow. Or it can be positioned to measure the oncoming flow as seen below:
