Airflow Measuring Stations and DampersAMS, AMD-23, AMD-33 & AMD-42
APPLICATIONThe AMS is an accurate airflow measuring station furnished with a properly sized pressure transducer that outputs a signal proportional to cfm.
A field-supplied controller can use the transducer's signal to regulate a modulating actuator to the target set-point.
The AMD series is an AMS that includes a modulating actuator which controls a low-leakage damper to regulate airflow volumes to a target set-point.
A field supplied controller can use the transducer's signal along with the flow formula: CFM = Area * K * (Ptransducer)
m to regulate a modulating actuator to the target set-point. (K and m are factory supplied variables specific to each measuring station.) An optional, factory-supplied LON controller that accepts a target flow set-point as an input (either analog or digital) and outputs a 0-10 Vdc signal can be used to position a damper (sold separately for AMS) proportional to the airflow.
FEATURES• Factory supplied 0-10 Vdc pressure transducer• Optional factory supplied LON controller
(0-10 Vdc, 2-10 Vdc, or 4-20 mA)• Galvanized steel sleeves available• Clean wrap• 24 Vac modulating actuator mounted externally or
internally (NEMA 2) (AMD models only).

AMCA CERTIFIED LEAKAGE DATAAir leakage is based on operation between 32 °F (0 °C) and 120 °F (49 °C).
Tested for leakage in accordance with ANSI/AMCA Standard 500-D, Figure 5.
Tested for air performance in accordance with ANSI/AMCA Standard 500-D, Figures 6, 7 and 8.
TorqueData are based on a torque of 7.0 lb.in./ft² (0.79 Nm) applied to close and seat the damper during the test.
Table 6. Leakage classification.
* Leakage Class DefinitionsThe maximum allowable leakage is defined by AMCA as the following:• Leakage Class 1A - 3 cfm/ft2 @ 1 in. wg
(class 1A is only defined at 1 in. wg).• Leakage Class 1
— 4 cfm/ft2 @ 1 in. wg— 8 cfm/ft2 @ 4 in. wg— 11 cfm/ft2 @ 8 in. wg— 12.6 cfm/ft2 @ 10 in. wg
PRESSURE DROPThis pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of 0.075 lb/ft3 (1.201 kg/m3 ).
Actual pressure drop found in any HVac system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVac system.
AMCA Test FiguresFigure 6 illustrates a ducted damper exhausting air into an open area (AMCA 5.2). This configuration has a lower pressure drop than Figure 8 (AMCA 5.5) because entrance losses are minimized by a straight duct run upstream of the damper.
Fig. 6. AMCA 5.2 - Pressure drop.
Figure 7 illustrates a fully ducted damper (AMCA 5.3). This configuration has the lowest pressure drop of the three test configurations because entrance and exit losses are minimized by straight duct runs upstream and downstream of the damper.
Fig. 7. AMCA 5.3 - Pressure drop.
Figure 8 illustrates a plenum mounted damper (AMCA 5.5). This configuration has the highest pressure drop because of extremely high entrance and exit losses due to the sudden changes of area in the system.
