1 Issue/Rev. 0.3 (6/02) Smith Meter TM PD Rotary Vane Meter Non Ferrous ircraft Fueling Meters Specifications Bulletin SS01009 The Smith Meter TM ircraft Refueling Meters are non ferrous, single case, rotary vane, positive displacement meters. They are available with a straight-through or an angle flow path, and with Victaulic, NPT, or Class 125 NSI B16.1 flat-face flanges. pplications include: refuelers, defuelers, truck loading, and accountability of other aircraft fuel transfers. Features Superior ccuracy - The Smith Meter TM Rotary Vane meter principle minimizes pressure drop across the measuring chamber, which reduces flow through meter clearances to maximize accuracy. Low Pressure Drop - Streamlined flow path provides low pressure drop. Positive and ccurate Registration - High torque drive calibrator with adjustment in 0.05% increments ensures accurate registration. Long Service Life - Low friction ball bearings, fixed cam-type timing, and rugged construction give sustained accuracy and long service life. Models T-11 and T-20 Principle of Operation The rotor, which revolves on stainless steel bearings, has four evenly-spaced slots. The slots control the position of two blades that are at right angles to each other. s liquid flows through the meter, the rotor and blades revolve around a fixed cam. Ball bearings fixed to the blades roll around the cam, causing the blades to move radially. The successive movement of the blades, outward toward the case wall, forms a measuring chamber of precise volume between the blades, rotor, case wall, and the bottom of the case. Four measuring chambers Models SD, SF, and SG Blade Path of Blades Flowing Liquid Cam Measuring Chamber Meter Housing Blade Bearing Rotor Models SD, SF, and SG The Most Trusted Name In Measurement

2 are produced for each revolution of the rotor, continuously and uninterrupted. Neither the blades nor the rotor contact the stationary walls of the measuring chamber. There is an illustration of a straight-through meter on Page 1. Port location of angle meters do not change this basic principle of operation.

6 Purchasing Specification Meter shall be of the positive displacement, rotary vane type with undisturbed flow passages to provide low pressure drop. The rotor shall revolve on low friction stainless steel ball bearings and have four blades that extend into the measurement chamber. The blades should be of ample area with a long moment arm to provide high driving torque at low flow rates and should be guided by a fixed cam arrangement. Neither the blades nor the rotor should contact the stationary wall of the measurement chamber. Revisions included in SS01009 Issue/Rev. 0.3 (6/02): Page 2 : dded repeatability ±0.02%.
