Introduction
standard interface found on PocketPC
®
s. The unit communicates with iCCUs,
and iMonitoring’s sensors over a wireless interface. The iCFR does not require a
battery since the host unit provides power. Other features include
programmable output power to an upper limit as defined in Appendix A, low
cost, and the ability to configure and upgrade the unit by the installer.
Electronic Flow Monitor (iEFM)
The Luna iMonitoring iEFM is an autonomous, wireless
electronic flow monitor which monitors natural gas flow
and provides total volumetric flow rate. Typically, the
sensor acquires five flow readings per day in monitor
mode. Each reading consists of an instantaneous
measurement, an average over the previous hour, and
an average over the previous 24 hours. An iCCU may
interrogate an iEFM at any time within a range of 2500
feet, and a portable device, such as a PocketPC
®
, can
poll the unit within a range of 500 feet. The iEFM
performs on-board data storage and processing, and
transmits over a secure, bidirectional radio link. The
unit optimizes power based on the current energy
storage, and requires only a single, solar-assisted battery. The iEFM is easy to
install, and is installler configurable and upgradeable. The unit incorporates an
IP65 ruggedized enclosure and meets UL-913 certification requirements for an
intrinsically safe device in Class I, Division 1, Groups C and D hazardous areas.
Tank Level Monitor (iTLM-1)
The Luna iMonitoring iTLM-1 is a self-contained, wireless tank
level monitor using Ultrasonic Sensing Technology to provide
temperature-compensated fluid level measurements in tanks and
silos. Typically, the sensor acquires five pressure readings per
day in monitor mode. An iCCU can communicate with a iTLM-1
within a range of 2500 feet, and a portable device, such as a
PocketPC
®
, can poll the unit within a range of 500 feet. The
iTLM-1 performs on-board data storage and processing, and
transmits over a secure, bidirectional radio link. The unit
optimizes power based on the current energy storage, and
requires only a single, solar-assisted battery. The iTLM-1 is easy
to install, and is installer configurable and upgradeable. The unit
incorporates an IP65 ruggedized enclosure and meets UL-913
certification requirements for an intrinsically safe device in Class
I, Division 1, Groups C and D hazardous areas.
