Smith MeterTM Turbine Meters
Specifications4" to 20" SentryTM Series
The Smith MeterTM Sentry Series Turbine Meter is arimmed, rotor-type meter with helical blades. Theyutilize both an upstream and downstream stator andhave tungsten carbide bearings with a hydrodynamicthrust balance system. They provide highly accuratemeasurement required for custody transfer of petro-leum liquids such as crude oil and refined productsin larger pipelines.
Features
Rimmed rotor for durability and high resolution pulseoutput.Helical blades for a streamlined flow pattern lesssusceptible to cavitation.All Stainless Steel wetted parts for corrosion-freeservice.Tungsten carbide bearings provide long life on lowlubricity liquids.Hydrodynamic thrust balance system to minimizefriction and wear on thrust bearings which allows forlong service life and high accuracy.NACE Compliance to MR0175/ISO 15156-1.
Options
Bidirectional flow allows the meter to accurately reg-ister flow in either direction.Multiple pickup coils are used when direction sens-ing or pulse security is required. A third pickup coil isavailable to drive auxiliary equipment, such as a back-up counter or prover.0.10% and 0.07% linearity available.High-resolution (HR) output available on 4" through8" meters to increase the pulse output per unit volumeto allow proving with a smaller-size pipe prover1.
Operating SpecificationsLinearity40.15% linearity over normal flow range.0.10% linearity over normal flow range.0.07% linearity over normal flow range.

InstallationThe meter should be mounted in a horizontal attitude(5) within a suitable flow conditioning assembly. It isrecommended that the meter be installed downstream ofa strainer for protection and upstream of the system con-trol valve.Refer to the installation manual for full instructions.
ApplicationsHigh ViscosityThe flow range of turbine meters is reduced considerablywhen metering viscous liquids.The minimum flow rate must be increased as the viscos-ity increases. The following relationships can be used toapproximate the increase (reduction in range) that willmaintain the stated linearity.Viscous Min. = Normal Min. x Viscosity (cP)
Rate Rate Meter Size (in)Note: Caution should be used when dealing with liquids that resultin a viscous minimum rate greater than two times the normal, sincevariations in operating temperature can result in substantial meterfactor shifts.Low DensityWhen metering light hydrocarbons such as LPG or otherliquids with specific gravity less than 0.8, the flow rangeshould be shifted upward. The amount of shift can beapproximated by multiplying the normal minimum andmaximum flow rates by the following factor:
0.9Rate Increasing Factor =S
Where: S = The specific gravity of the liquid being metered.The increased flow rate should not exceed the meter'soverspeed flow rate.Minimum Back PressureIn order to prevent cavitation, API M.P.M.S. Chapter 5recommends a minimum back pressure according to thefollowing:
BP = (2 x P) + 1.25 VpWhere: BP = Minimum back pressure
P = Pressure drop at maximum flow rateVp = Absolute vapor pressure at operating
temperatureExample:6" Sentry at 4,000 BPH - P = 6 psi.Absolute vapor pressure of butane at operating tempera-ture - Vp = 50 psia.Min. BP = (2 x 6) + 1.25 (50)
= 74.5 psi
Overspeed130% of maximum flow rate for 5% duty cycle.End ConnectionsClass 150, 300, 600, ANSI B16.5, 125-250 AARH finishraised face (RF) flanges.Consult factory for higher working pressure or other typesof flanges.Maximum Working Pressure - PSI (kPa)
