Sensor Maintenance.
Procedure for the Removal of a MicroFlow Sensor
From time to time it may be necessary to remove the transducer for cleaning or
maintenance purposes, the below procedure is to ensure that this is done carefully
with regard for the health and safety of the operator involved, and without damage
to the sensor.
If it is necessary to replace the sensor for any reason, the following procedure
should be followed:
•
Disconnect the transducer wiring from the controller or any junction box as
shown in the
Terminal Connections section of this manual, and remove the
sensor cable from the controller/enclosure.
•
Remove any bolts or fittings that the sensor may be attached to, allowing the
cable to be pulled through with ease.
•
If using a Pulsar angled bracket, the sensor head is mounted onto the end of
the bend via its process fitting, this should be carefully unscrewed in an
anticlockwise direction. Ensure that the sensor is not dropped or knocked as
this can cause damage to the unit.
•
When replacing the sensor, care must be taken not to over tighten the unit as
this can cause damage. Hand tight is sufficient.
•
Ensure that the green dot has been positioned in the direction of the flow of
the vessel, this will obtain optimum velocity readings that are available.
Please refer to ‘
Fig.3
’ in ‘
Chapter 2-Installing the sensor
’
section on how
to do this.
•
When the sensor has been replaced for the application, and re-connected to a
controller and the power re-applied, the unit will re-initialise and will begin
the process of acquiring flow and velocity readings.
•
When refitting or replacing a sensor, ensure that it is installed in accordance
with ‘
Chapter 2-Mounting a sensor to a bracket
’.
•
When replacing the sensor for a new one, upon connecting the sensor to the
Pulsar controller and powering the devices up, the new sensor will
automatically adopt the Baud rate of the controller using the
MicroFlow
protocol. Allowing you to continue use without the need to change any
parameters.
Important Information
Before attempting to remove the sensor for cleaning or any other
purpose, the power to the unit should be disconnected.
