　　产品描述

　　The FPT-6000 is a highly accurate averaging pitot tube which generates a pressure differential between its upstream (stagnation) ports and its downstream (static) ports that is proportional to the flowrate squared (Q2 ). The differential pressure can then be measured by a differential pressure transducer (PX760 Series) to provide a 4-20 mA output which is proportional to the flowrate squared. This can then be read out as flowrate by devices with square root extraction, such as OMEGA’s DPF64-SQRT meter or FC-20 mass flow computer. The FPT-6000 can be used to measure clean, low viscosity liquids, gases and steam in a variety of piping systems and pipe sizes (to 72" and above on special order).

　　The FPT-6000 offers the following advantages over orifice plates: easy, low-cost installation (weld 1 small coupling into place vs. 2 large flanges); much lower permanent pressure loss; low maintenance (occasionally forcing gas through the pressure ports clears the sensing ports when dirt is a problem); and good resistance to wear. Bi-directional flow measurement capability is standard. And, with special double-mount construction, the flow ranges listed can be extended by to up to 4 times

　　Sizing Equations

　　1. Any Liquid: ΔP (in. H2O) = Q2(GPM) x Sf / K2 x D41 x 32.14

　　2. Steam or Any Gas (steam requires min ΔP of 10" H2O): ΔP (in. H2O) = Q2(lb/hr) / K2 x D41 x ρ x 128,900

　　3. Any Gas: ΔP (in.H2O)= Q2 (scfm) x SS x (T + 460) / K2 x D41 x P x 16,590

　　Where:

　　ΔP = differential pressure (in inches H2O)

　　Q = flowrate

　　K = flow coefficient (see “how to order”)

　　D1 = inside diameter of line size (in inches for square and rectangular ducts use): D1 = √(4 x height x width / Π)

　　P = static line pressure (psia)

　　T = temperature (in °F)

　　ρ = density of medium (in pounds per cubic foot)

　　Sf = Sp. Gr. at flowing conditions

　　Ss = Sp. Gr. at 15°C (60°F)

　　NOTE: Use of these equations for liquids yields an accuracy of ±2% of rate. When used for steam, accuracy is ±10% of rate (when steam tables are used). Gas equation yields ±2% of rate accuracy from 21 to 204°C (70 to 400°F) and 0 to 150 psig (when gas is not near its critical point). A ±1% of rate accuracy requires the use of more precise equations which account for shift in K with change in flowrate, gas compressibility, etc. Request a precision flow calibration sheet and please supply the following data: name of fluid, specific gravity, pressure, temperature, inside pipe diameter, viscosity, steam quality, degrees superheat, and ratio of specific heat at constant pressure to that at constant volume (for gas velocities approaching 500 fps).

　　注: Max. differential pressure shown is for up to 150°C (300°F). Above 150°C (300°F), reduce value by 4% per 56°C (100°F). ?
