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).
