About the MicroFlow-i
The MicroFlow-i is a 2-wire loop-powered non-contacting velocity sensor,
with hazardous area approval. 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-i’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.
Perfect for remote monitoring or when there is no mains power available, due
to its low power consumption. To access flow velocity data, use Pulsar’s
MicroFlow-i HART PC or HART protocol.
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-i, these are listed below:
•Non-contact velocity measurement.
•Loop powered and ideal for remote monitoring.
•Low-power consumption.
•Hazardous area approval (Ex ia) for Zone 0.
•‘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
•Maintenance free.
•No interruption to operational flow.
•Can be installed in addition to existing in process contact measuring
devices.
•Easily setup using MicroFlow-i HART 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-i
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-i has been designed to provide maintenance free
performance. The MicroFlow-i i is also intrinsically safe (Ex ia) for Zone 0.
The MicroFlow-i can be mounted via a rear 1” BSP to M20 thread adapter
(supplied with unit). The MicroFlow-i is loop powered and gives a 4 to 20mA
output which is proportional to the flow velocity. A ‘fault condition’ alarm will
give out a reading of either 3.8mA or 22mA.
The 2 wire sensor can either be used in digital HART mode or as 4-20mA loop
powered device. The MicroFlow-i loop powered version can be set up using a
HART modem with either proprietary HART software such as Pact ware or Pulsar
MicroFlow-i HART PC software.
Boot up time from power up to stable reading: cold boot 8.5 seconds, warm boot
4 seconds (if within 12 hours from last start up).
