About the
MicroFlow
The MicroFlow is a non-contacting velocity sensor. The sensor provides
reliable flow velocity measurements using short pulses of micro-waves, which
are transmitted by an enclosed antenna. When reflected off a moving surface,
the signal experiences a shift in frequency characteristics. The reflected signal
is captured by the on-board microprocessor via the antenna, and analysed to
determine the velocity.
The MicroFlow’s compact and versatile design makes it easy to install and
ideal for confined spaces. Housed in a robust enclosure coupled with a fully
encapsulated microwave antenna, it provides an effective fit-and-forget flow
velocity solution.
PC software is available to allow setup and run diagnostics using MicroFlow
PC via a RS 485 connection. The MicroFlow is compatible for use with
Pulsar’s, FlowCERT, Velocity Interface and Ultimate controllers to obtain
velocity readings. The MicroFlow can also be retrofitted to replace existing in-
process contacting sensors.
Overall the device has outstanding stability, accuracy and repeatability.

Benefits
Combined with the ease of programming there are many other benefits to using
the MicroFlow, these are listed below:
•Non-contact velocity measurement.
•Retro-fit capability and low-cost installation.
•Hazardous area approval (Ex mb) for Zone 1.
•Monitors flow over natural channels such as streams and rivers.
•‘See through’ capability for enclosed plastic pipes and concrete (not
reinforced) channels.
•Suitable for abrasive and aggressive materials.
•Resilient to liquid vapour, wind or temperature.
•No minimum liquid level required for measurement
•Virtually maintenance free; not affected by sedimentation, so there is no
need for regular cleaning.
•Compatible with Pulsar’s FlowCERT, Velocity Interface and Ultimate
controllers, with retrofit capability for in-contact sensors.
•Can be installed in addition to existing in process contact measuring
devices.
•Easily setup using MicroFlow PC.
•The sensor is capable of monitoring flow of very shallow liquid,
mitigating the constraint associated with in-liquid techniques.

Functional Description
Based upon state-of-the-art micro-wave sensing technology, the MicroFlow
integrates Pulsar’s innovative and award winning DSP (Digital Signal Processing)
platform, offering you a cost effective solution with excellent reliability and
performance.
The Pulsar MicroFlow has been designed to provide maintenance free
performance.
The MicroFlow automatically matches to the protocol and Baud rate of the
controller. When it is connected to a controller and powered up, after approx. 20
seconds the sensor will adjust to the Baud rate of the controller it is connected to.
Limitations of use
1. The MicroFlow must be routinely inspected to avoid the build-up of dust
layers when installed in to Zone 21 & Zone 22.
2. Electrostatic hazard –The MicroFlow must only be wiped with a damp or
antistatic cloth.
3. Only leaded little fuses (0242 series) of 100mA should be used with the Ex
mb approved MicroFlow.
4. The outer enclosure is made from Valox357U, consider the performance of
this material with respect to chemicals that may be present in the hazardous
area.
5. The equipment should not be used if there are any cracks/damage to any part
of the enclosure.
