Micro Motion 7827 Digital Viscosity Meter The Micro Motion 7827 digital viscosity meter is an accurate measurement instrument used for continuous real-time process control of liquid viscosity and density in pipeline, slipstream/bypass and tank installations. About the 7827 Digital Viscosity Meter The 7827 digital viscosity meter is used for measurement or control of on-line process viscosity. The meter is used in applications requiring continuous on-line viscosity measurement in pipelines and tanks. The 7827 meter is available as a long-stemmed version for top mounting in open or closed tanks. The 7827 digital viscosity meter works with the Micro Motion Model 7950 or Model 7951 signal converter to directly measure on-line viscosity, density, and temperature allowing a true measurement of dynamic and kinematic viscosity. Additionally, parameters such as referred viscosity, referred density, and viscosity index can also be determined using the signal converters built-in calculations. These calculations are based on API and ASTM D341 standards. With its multiple digital and analog communication connections, PID control, and alarm contacts, the combination of the 7827 meter with the 7950/7951 signal converter allows you to manage complex process and control applications where on-line measurements need to be referenced to laboratory conditions. Advantages Fully integrated fit and forget digital viscosity and density measurement for monitoring and control Continuous, fast response digital measurement for closed loop control Measurements of viscosity and density at line and reference conditions Operates at viscosities up to 20,000 cp No moving parts means virtually no maintenance Integral Class B PT100 temperature sensor Hazardous-area approved (ATEX and CSA) Long-stemmed version is suitable for use on open and closed tanks and available in stem lengths up to 13 ft (4 m) Insensitive to vibration Direct insertion meter suitable for high-line pressure Contents Typical applications........................ 3 Typical industries.......................... 3 Principle of operation....................... 3 Features................................. 4 Performance............................. 5 Temperature specification................... 5 Pressure ratings........................... 6 Hazardous area classifications............... 6 General classifications..................... 6 Materials of construction.................... 7 Weight.................................. 7 Electrical................................ 7 Dimensions.............................. 8 Installation.............................. 11 Ordering Information...................... 12 2 Micro Motion 7827 Digital Viscosity Meter

Typical applications Heavy fuel oil (HFO) heater control to burners and engines Lube oil viscosity control Interface detection in multi-product pipelines Mass flow, when used in conjunction with a volumetric flow meter Product mixing and blending Typical industries Oil and petrochemical Refining Power Heavy Fuel Oil (HFO) blending and bunkering Principle of operation The 7827 digital viscosity meter uses a vibrating fork technology to measure density and viscosity. As the liquid density changes, it affects the vibrating mass of the meter. The change in vibrating mass then affects the resonant frequency. Viscosity is a function of the bandwidth, which is an indication of the damping associated with the liquid. The following figure illustrates how the 7827 meter with a 7950/7951 signal converter uses the resonant frequencies at point A (the lower 3 db point) and at point B (the upper 3 db point) to digitally calculate the density, bandwidth and quality factor. These measurements then give digitally determined values of fluid density and viscosity. Product 1 Low Viscosity Product 2 High Viscosity Response amplitude Product 1 Product 2 Frequency (Hz) Bandwidth = Point B Point A Resonant Frequency = (Point A + Point B) / 2 Quality Factor = Resonant Frequency / Bandwidth Micro Motion 7827 Digital Viscosity Meter 3

Features The 7827 digital viscosity meter works with the Model 7950 or Model 7951 signal converter to measure line viscosity, density, and temperature; and, calculate referred viscosity and base density using ASTM and API tables. Additionally, parameters such as API and specific gravity also can be determined using the signal converter s built in calculations. Any of these parameters can be used to drive ma outputs from the signal converter. See 7950/7951 signal converter features. Installation and application flexibility The 7827 meter can be easily installed in a slipstream/bypass, pipeline, open tank, pressurized vessel, or flow-through sample chamber. The availability of a choice of construction materials and connections allow this meter to be used in a wide range of applications. Low maintenance required Because the 7827 digital viscosity meter has no moving parts, minimal maintenance is required, leading to lower overall operating costs. The vibrating forks are available with PFA coating to assist self-cleaning. PFA is ideal for hydrocarbon applications. Care should be taken if the PFA coating is to be used in a corrosive application. Please consult your local Micro Motion sales office. Raw frequency output electronics The 7827 digital viscosity meter is designed to operate with the Micro Motion Model 7950 and Model 7951 signal converters. See 7950/7951 signal converter features below. No field calibration required The 7827 digital viscosity meter is factory-calibrated and no field calibration is required. The calibration is traceable to UK National Standards through the Micro Motion onsite accredited laboratory. Auto-ranging measurement Each factory calibration is designed to achieve maximum accuracy. The calibration measurements are: 0.5 to 10 cp, 10 to 100 cp, 100 to 1000 cp, and 1000 to 12,500 cp. An auto-ranging facility is provided for applications where the liquid viscosity extends over one or more of the current operating calibrated ranges. Fluid characterization using viscosity Because the 7827 meter is used with a 7950/7951 signal converter, complex measurements of liquid viscosity at conditions away from line temperature and pressure can be performed. Parameters such as viscosity at reference temperature and viscosity index are available. 7950/7951 signal converter features Inputs from meter: Line viscosity (bandwidth) Line density (frequency) Temperature (PT100) 7950/7951 outputs: Status Four 4 20 ma outputs (optional: 8) RS-232C/485 Typical 7950/7951 calculations: Referred kinematic viscosity Line dynamic/kinematic viscosity Referred density Specific gravity % concentration 4 Micro Motion 7827 Digital Viscosity Meter
