.jpg) |
|
| The OAFE-1550 is an AMCA certified outdoor airflow measurement system capable of producing an overall ±0.5% accuracy through the velocity range of 200 to 1,200 fpm. The airflow measurement system consists of an integral signal processor and multipleairflow elements, factory mounted and pre-piped in a casing designed for flanged connection to ductwork, control dampers, louvers, etc. An optional inlet bell is available for plenum applications. The signal processor accepts a temperature input signal for air density compensation for standard (scfm) or actual (acfm) airflow calculations. |

Device monitoring and configuration can also be performed by a building management system through either a LonWorks®, BACnet-MS/TP® Master or Modbus® RTU Slave communication network. An optional controller is available that utilizes a proprietary algorithm which results in true three mode control incorporating proportional band, integral (reset) and inverse derivative (P, I, 1/D) controller functionality and tuning. The controller will provide responsive modulation of a control damper or variable speed drive guaranteeing that a constant airflow is maintained. An economizer override option is available that allows the building management system to override the minimum outdoor airflow rate. |

| FE-1050 Fan Inlet Airflow Sensing Elements |
| |
 |
|
The FE-1050 is an airflow measuring element assembly specifically designed for installation in the inlet cone of centrifugal fans or inlet bell of vane-axial fans. The design of these primary elements provides a means of accurate measurement of fan capacity along with ease of installation. Each assembly is complete with two airflow measuring elements and pivot mounting hardware. Flow transducers are sold separately.

| FE-1000 Duct Insertion Airflow Sensing Elements |
| |
 |
|
| The FE-1000 is an insertion type airflow sensing element designed for quick, easy installation through a small cutout in the existing ductwork. Where multiple elements are required for proper duct traversing, the output ports are manifolded together, external to the ductwork. Flow transducers are sold separately. |

| FE-1500-FX Duct Mounted Airflow Measurement Station with Straightener |
| |
 |
|
| The FE-1500-FX airflow measurement station has been developed for use in duct systems having a highly turbulent condition at the point of measurement. The FE-1500-FX consists of single or multiple airflow elements factory mounted and pre-piped in a casing designed for flanged connection to the ductwork and incorporates an airflow straightening section using honeycomb having a ½ inch opening by 3 inch depth. Standard materials consist of a G90 galvanized casing, 6063-T5 anodized aluminum flow sensors, and 3003 aluminum airflow straightener. Flow transducers are sold separately. |
