Ebtron Airflow Monitor Station

Return to Engineering Main Menu

Basic Ebtron Info

Ebtron airflow monitoring stations (AFMS) are typically mounted on the OA intake damper when specified for the job.  They can also be used to measure CFM on any damper type, coil face area, blower inlet, etc.  The GTA116-PC model is the standard for S-4, and our standard part numbers starts with 4091530xxx.  An AFMS uses a series of probes and sensors to measure the airflow through the damper.  (ADD MORE TECHNICAL INFO HERE - TDM; 1/22/20).

 

Ordering Info

When ordering an Ebtron AFMS, you must send the design info to Purchasing, so they can add details to the P.O. and relay the info to Ebtron.  When ordering, you must include:

 

• Damper Size (width x height).
  • Note: This is total damper size if more than one damper are used for a single AFMS.
  • E.G. 48" x 60" total size for two (2) individual 24" x 60" dampers.
• Mounting Type (e.g. Stand-off mounting).
• Cable Length (e.g. 25')
• Maximum Airflow (CFM) thru Damper.
• Face Velocity (FPM) thru Damper @ Max CFM.
• Drawing showing the location of the AFMS in the unit.
• Job Location (i.e. city, state).
• Seasons-4 Part Number(s)

 

When ordering the AFMS, it is preferred that Ebtron determines the required number of probes and sensors.  Our part number descriptions will not show this info for all future new P/N setups.  Any existing P/N that has the correct damper size for your application can be used, but it is recommended that any detail describing the number or probes, sensors and cable length be removed from the existing P/N descriptions.  Ask Purchasing to make this change before issuing the P.O.

It is possible to use a single AFMS for multiple OA intake dampers (e.g. OA intake dampers on each side of the unit).  If this is the case, Ebtron must be notified that the AFMS will be used on more than one damper, so they can determine the correct number of probes and sensors.

Also, make certain the requested cable length is adequate to run from the probes to the location of the AFMS controller.  A 25' cable is our standard length, but 50' is available if needed.  If the unit's control panel is a relatively far distance away from the AFMS probes, a separate panel is installed for the AFMS controller.

Subject: D415 CORLISS HIGH SCHOOL - Ebtron Order

 

Robert,

For FO #D415, we are ordering three Ebtron airflow station. I have listed the S4 part numbers, airflows, damper sizes, and velocities on the table below.

Unit Tag	OA Damper (WxH inches)	Face Velocity (fpm)	CFM	Part #	First Description	Second Description
S-20	30”X60”	1431	17,889	4091530235	GTA116-PC FLOW STATION	(30X60) DAMPER
S-22	30”X72”	1552	23,283	4091530210	GTA116-PC FLOW STATION	(30X72) DAMPER
S-23	30”X60”	1042	13,031	4091530235	GTA116-PC FLOW STATION	(30X60) DAMPER

 

Each airflow station will measure ONE outdoor air intake dampers. The OA intake damper sizes are listed on the table above for each unit.

FYI: we may have ordered these part numbers in the past, but the design and orientations may be different than the requirements for this job.

Please have Ebtron design the GTA116 system with the appropriate number of probes and sensors for each unit. The probes will have stand-off mounting. We need 25’ cable length. Attached are the unit drawings showing the locations of the dampers and the station locations are still being finalized but will be within 25’. If more information is required, please let me know. Thanks for the help.

Subject: FO #B866 Ebtron Ordering Info

 

Robert,

For FO #B866, we are ordering one (1) Ebtron airflow station for each unit for a total of two (2) airflow stations. The following part is required for each unit (RTU-1 & RTU-2):

 

4091530196 (Qty 1 per unit) - GTA116-PC FLOW STATION (36X96)

 

For each unit, the single airflow station will measure the airflow of two (2) outdoor air intake dampers. Each damper is 18” x 96”. Please have Ebtron design the GTA116 system with the appropriate number of probes and sensors. The probes will have stand-off mounting. We need 25’ wire length. Attached are the unit drawings in case Ebtron needs them.

 

Please add all of this information to the PO, so Ebtron knows what is required. FYI: we have ordered this part number in the past, but the design and orientation was different than the requirements for this job. If more information is required, please let me know.

 

Thanks,

Tim

Subject: FO #B223 Ebtron Ordering Info

 

Rick,

For FO #B223, we are ordering three (3) Ebtron airflow stations. This job is very similar to FO #A829. I will include as much information as I can in this email, so you can forward it on to Bill Jones at Ebtron. Bill can review the attached email from the previous job for reference. The following parts are required for each unit:

 

P/N 4091530167 (Qty 2) - GTA116-PC FLOW STATION (30x30)

P/N 4091530190 (Qty 1) - GTA116-PC FLOW STATION (12x12)

 

Here is a description of each required airflow station:

1. P/N 4091530167 (Qty 1)
   1. Measures a 30” x 30” OA damper
   2. Standoff Mounting
   3. 25’ Wire Length

 

2. P/N 4091530167 (Qty 1)
   1. Measures a 30” x 30” SC coil face area
   2. Standoff Mounting
   3. 25’ Wire Length

 

3. P/N 4091530190 (Qty 1)
   1. Measures a 12” x 12” minimum EA damper.
   2. Insertion Mounting
   3. 25’ Wire Length

 

Please have Ebtron design the GTA116 systems with the appropriate number of probes and sensors. Attached is the unit drawing. It shows the locations of the airflow monitoring stations. All probes mount upstream of the measured opening (i.e. damper or coil). If more information is required, please let me know. Thanks for the help.

 

Thanks,

Tim
