Page 8: Section 2: Installation
Section 2: Installation 2.1 System Explanation The Accutron airflow sensors are compact and reliable instruments, especially designed for measuring airflows in mining environments. The Accutron IS Drift System is for airflow measurements in mine drifts whereas the Accutron IS Fan System is for measuring the flow output of large mining fans. Each system consists of an Indicating Transmitter, cabling and two “ultrasonic sensor”... -
Page 9: Choosing A Location
2.2 Choosing a Location The best location to install the instrument is in a straight section of tunnel that is at least 3 tunnel widths long. In such a section, the airflow distribution will be well behaved with a maximum airflow in the center and minimum airflow on the sides (Figure A). -
Page 10: Mounting The Sensors
2.4 Mounting the Sensors When planning a mounting location for the wall mount sensors, we recommend mounting one sensor near the top of the drift or duct and the other sensor located near the bottom downstream from the first on the opposite side, with an “imaginary line” between them intersecting the airflow at a typical angle of 120 degrees. -

Page 22: Section 4: Modbus
Section 4: Modbus The RS485 interface in the Accutron IS is optically isolated from the rest of the unit. This is why an external source of 5VDC is required.
