The **Series AFG Averaging Flow Grid** is a fundamental pressure-sensing device designed to sense velocity pressure in an air duct. When this output is connected to a suitable measuring instrument (i.e. manometer, pressure transducer, etc.) it may be used to determine air velocity or air flow rate. 

## **SPECIFICATIONS** 

**Service:** Monitor air or compatible gas flow. 

**Wetted Materials:** 304 SS, PVC, polyurethane, acetyl plastics, and neoprene rubber. 

**Accuracy:** ±5%. 

## **BENEFITS/FEATURES** 

- Kit complete with 2 probes and installation hardware 

- Trimmable length for any duct size up to 60˝ 

- Alternative to costly air flow stations 

## **APPLICATIONS** 

- To display differential pressure, velocity or volume flow using a micro manometer, gage or transmitter 

- To give a warning of over or under flow rate using a pressure switch 

- To control air supply in a system by connecting the grid to a pressure transmitter with an electrical output which can be used to feed into a control system 

- To display differential pressure on a simple fluid manometer to give visual indication of changes in volume flow rate in the duct 

**Maximum Temperature:** 176°F (80°C). 

**Velocity Range:** 295.2 ft/min to 5904 ft/min (1.5 to 30 m/s). **Diameter of Tubes:** 5/16˝  (8 mm) or 5/8˝ (16 mm). **Maximum Duct Diagonal:** 60.4˝ (153.4 cm). **Maximum Duct Diameter:** 59.4˝ (150.9 cm). **Process Connections:** 5/16˝ barbed. 

**Weight:** AFG-1: 1 lb (454 g); AFG-2: 3 lb (1361 g).
