Duct Measurement
The FE-1000 airflow sensing element is a head type device, which generates a differential (velocity) pressure signal similar to the orifice, venturi, and other head producing primary elements. The FE-1000 is constructed so that strategically located sensing ports (based on duct size) continually sample the total and static pressures, when inserted normal to flow. The total pressures sensed by the upstream ports are continually averaged within the element in an isolated chamber. The static sensing ports (located where the influence of the velocity head is zero) are averaged in a second isolation chamber. Each chamber is then connected to one side of a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.

Airflow Measurement
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. The FE-1050 airflow averaging element assembly is a head type device, which generates a differential (velocity) pressure signal. The basic design is a “cylindrical tube within a cylindrical tube” creating independent chambers which permit the simultaneous measurement of both total pressure and static pressure. Multiple total and static pressure sensing ports (which are strategically located based on the known pressure distribution over a cylindrical surface) provide comprehensive averaging of the velocity variations. Each chamber is then connected to one side of a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.

Airflow Measurement
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 multiple airflow 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.

Flo Transducers
The FAATS-1000 Fan Array Airflow Totalizing System has been specifically designed to provide a cost effective means for accurate (±0.25%F.S.) airflow measurement of up to forty individual fans within a single fan array or forty combined fans in an air handling unit with both supply and return fan arrays. The individual airflow rate of each fan in an array is indicated on a seven inch, full color, Human-Machine-Interface (HMI) touch screen panel as well as the summed (total) airflow rate of each array. The total airflow rate of each array is also made available to the Building Management System (BMS) via dedicated field selectable 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA analog outputs. Individual fan airflow rates and total airflow rates for each array are also available to the BMS via BACnet®-MS/TP Master or Modbus® RTU Slave network communications. Independent monitoring of each fan allows the FAATS-1000 to identify and alarm fan failures and airflow rate discrepancies between fans.

Flo Transducers
The MicroTransEQ flow transducer utilizes a 24 bit A/D converter for signal processing and can produce accuracies of ±0.1% of reading. The ultra low 0.03"w.c. differential pressure (693 fpm at standard air density conditions) full scale operating range and the auto zeroing function provides accurate air flow measurement down to 100 fpm making this product ideal for outdoor air flow measurement applications and for use on projects seeking to obtain credit for IEQ Credit 1: Outdoor Air Delivery Monitoring under the LEED® Green Building Rating System. The MicroTransEQ also accepts a temperature input signal for air density compensation for standard or actual airflow calculations. For easy use on fan inlet applications with piezometer ring systems, the MicroTransEQ incorporates a special piezometer ring flow algorithm with easy flow coefficient entry through display menus. A 4-point flow correction and K-factor field menu are included to reduce time and save money spent on balancing. 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.
