The toothless designworking with the fluid being measured provides a complete viscous seal within the measuring chamber. This sealing effect provides for greater flow measurement accuracy.The displacement of the fluid is translated via a magnetic or Hall-effect pick-up into a pulse output that is proportional to the flow.The unique design of the FTB3000 oval gear meter incorporates two smooth(toothless) oval gears positioned 90 degrees out of phase. The measurement gears are held together by two timing gears. The standard meter contains no seal between the measurement chamber and the timing chamber. The timing gears have a pitch diameter equal to the outside diameter of the measurement gears. The flow through the meter measurement chamber follows the path of least resistance. Therefore no liquid passes through the center cavity between the measurement gears. The fluid is displaced from the inlet to the outlet via the area between the smooth oval gear and the inner diameter of the meter housing.Conventional oval gears have teeth that mesh. One of the advantages of smooth oval gears is that the viscous flow does not get trapped or squeezed between the gears. Typically oval gears need to have cuts made in the teeth to allow high viscosity fluids to pass. These cuts result in a decrease in accuracy.SPECIFICATIonSService Fluid: Clean liquids max particle size 3.175 mm (0.125")Accuracy: ±0.25% of readingViscosity: 100 cSt or greaterRepeatability: ±0.05%Operating Temperature:FTB3001: -240 to 176°C (-400 to 350°F)FTB3002: -40 to 150°C (-40 to 302°F)Operating Pressure: 3000 psig standardWetted Parts: 316 SS body and gears with PEEK? gear seatsBearings: Shielded self-lubricating 440 SS ball bearingsConnections: 1 MNPTPick Up Coil: Magnetic type or Hall Effect (6 to 24 Vdc power)Calibration: Ten-point calibration traceable to NIST @ 100 centistokesWeight: 7.53 kg (16.6 lb)产品型号/产品描述FTB3001 2 to 25 GPM rate magnetic pick-upFTB3002 0.02 to 25 GPM rate Hall-effect sensorAccessoriesU24Y175 24 Vdc 175 mA power supplyDPF701 Panel meter for rate or total注释: Add suffix “-150LBF” (150 lb stainless steel flange) or “-300LBF” (300 lb stainless steel flange) to the part number and $250 to the price.Comes complete with operator’s manual mating connector and 10-point NIST calibration.美国omega FTB3001椭圆齿轮流量计相关产品：FTB2005-C流速传感器 美国omega-omega流量计-FTB2005-C流速传感器 美国omeFTB2006流速传感器 美国omegaFTB2001-C传感器 美国omegaFTB2002传感器 美国omegaFTB-1400-MD数显流量计 美国omegaFTB2005流速传感器 美国omega_仪器仪表_#
