. The SERIES AFG Flow Grid is an outstanding simple yet accurate cost effective alternative to other duct mounted pressure sensors. Once installed and connected to a suitable measuring instrument, the device will provide years of trouble free monitoring of both air and gas flow. Installing the AFG Flow Grid is quick and easy, the AFG is supplied in kit form to allow both workshop and on-site installation into a wide range of square and circular ducts up to approximately 60'. The AFG Flow Grid is a fundamental pressure sensing device designed to transmit a continuous differential pressure signal. When this output is connected to a suitable measuring instrument (i.e., manometer, pressure transducer, etc.), it may be used to determine air velocity and volume flow rate.
How the AFG Flow Grid Works The AFG Flow Grid consists of two tubes mounted diagonally across a square or rectangular duct, or diametrically across a round duct. The tubes are drilled with a series of equi-spaced holes. The holes in one tube face directly upstream and sense total pressure, while the pairs of holes in the second tube also face forward but at an included angle of 79 degrees, sensing static pressure. The total and (sub) static pressures are averaged along the length of each tube and provide pressure signals at connectors outside the duct wall.
The pressure differentials across these connectors constitute the output signal. Product Applications. To display differential pressure, velocity or volume flow using a micro manometer, gage, or transmitter.
Pitot tube, while the second answer (14.14) corresponds to an averaging Pitot tube. To account for these averaging errors, manufacturers of averaging Pitot probes often include some form of correction factor.

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.

. The SERIES DS In-Line Flow Sensors are two Series of averaging Pitot tubes for compatible gases and liquids that provide accurate and convenient flow rate sensing, for schedule 40 pipe, when purchased with suitable differential pressure gage with appropriate range. The Series DS-300 Averaging Flow Sensors are designed to be inserted in the pipeline through a compression fitting and available for pipe sizes from 1 to 10' (2.5 to 25.4 cm).
Accessories include adapters with 1/4' SAE 45° flared ends compatible with hoses supplied with the Model A-471 Portable Capsuhelic® Gage Kit. The Series DS-400 Averaging Flow Sensors are designed for insertion lengths up to 24' (61 cm) and include a pair of 1/8' NPT x 1/4' SAE 45° flared adapters which are compatible with hoses used in the Model A-471 Portable Capsuhelic® Gage Kit. The supplied solid brass mounting adapter has a 3/4' dia. Compression fitting to lock in required insertion length and a 3/4' male NPT thread for mounting in a threaded branch connection (not included). California Residents: for Proposition 65 WARNING.

Multiple sensing point measurement and built-in averaging capability eliminates the need for “traversing” the flowing stream with single point velocity pressure measurement saving time. Extremely reliable, proven technology, Pitot tubes, have been used in flow measurement for years.
All models include convenient and quick-acting quarter-turn ball valves to isolate the sensor for zeroing with 1/8' female NPT valve assembly process connections. Furnished with instrument shut-off valves on both pressure connections with 1/8' female NPT connections rated at 200 psig (13.7 bar) and 200°F (93.3°C). Where valves are not required, they can be omitted at reduced cost.
The Series DS-400 Averaging Flow Sensors are quality constructed from extra strong 3/4' dia. Stainless steel to resist increased forces encountered at higher flow rates with both air and water.
