1 Issue/Rev. 0.1 (4/99) S-Mass Meter S50-D Density Specifications ulletin SS0M020 The S-Mass Density derives its name from the S-shaped tubes of the flow sensor. This patented geometry produces a high signal-to-noise ratio for maximum response to the generated Coriolis forces. The S-Mass is a highly accurate vibrating tube densitometer for measuring process fluid density, net solids, brix, or calculating gross fluid volume. Features Stable, linear, and accurate density output signal even by changes in product temperature, pressure, density, flow rate, or viscosity Serial data link to flow controller Three pulse outputs Intrinsically safe with galvanic barrier module Patented S-shape tubes for maximum flow sensitivity ll stainless steel Factory pre-calibrated User PC programmable for setup, tune, and calibration pprovals Inline installation kit available Flow through indication S-Mass S50-D Principle of Operation The frequency of vibration of the S-Mass meter tubes varies with fluid density. The Micro-Pak transmitter measures this frequency, and provides a density output (Figure 3). S-Mass meters precisely determine mass flow by measuring the effects of Coriolis forces on a pair of S-tubes, which are electromagnetically vibrated. The measurement principle is based on a variation of Newton s Second Law of Motion: Force = Mass x cceleration s fluid (V) proceeds through the S-tubes, it experiences an acceleration transverse to the direction of flow, and Coriolis Forces (F c ) result. The Coriolis force causes the displacement of the vibrating tubes to become slightly distorted or out of phase (Figure 1). Motion sensors, placed symmetrically about the midpoints, generate electrical signals with a relative phase shift that is proportional to mass flow (Figure 2). These electrical signals are processed in the Micro-Pak transmitter module to provide various outputs.
