SECTION 1.0: GENERAL INFORMATION
Thank you for purchasing the ELECTRA-flo Thermal Airflow & Temperature Measurement
System. As our valued customer, Air Monitor’s commitment to you is to provide fast,
reliable service and assistance while continuing to offer you the most accurate and reliable
products to meet your flow measurement needs.
1.1: PURPOSE OF THIS MANUAL
This manual provides information regarding the installation, operation and maintenance of
your thermal airflow measurement system. This is NOT, nor is it intended to be an electrical
or HVAC trade manual.
This manual is the basic reference tool for the ELECTRA-flo G5 Transmitter, including its
power connection and associated outputs. The complete system consists of the transmitter
and associated probe arrays or stations. Refer to supplemental documents for additional
information.
1.2: TYPICAL THERMAL AIRFLOW MEASUREMENT SYSTEM INSTALLATION
Air Monitor’s ELECTRA-flo G5 system accurately measures the average velocity of flowing
air by means of thermal dispersion sensors located in airflow ducts. Temperature is also
measured via these sensors. The G5 transmitter can average data from a maximum of 32
individual flow sensors. The G5 transmitter is designed to measure airflow in a single
duct or fan inlet. An optional true dual channel version provides two separate airflow
measurement channels in one transmitter. Analog outputs and an RS485 interface for
BACnet or MODBUS convey data from the ELECTRA-flo to local controllers or a BMS.
Physical installation details for the ELECTRA-flo probe arrays or flow stations can be found
in the ELECTRA-flo Installation Procedures guide.
