FANN Instruments Drilling Fluids, Testing Meter

Fann Instrument Company has been the predominate supplier of instruments for drilling fluids analysis since 1939. Their instruments are used in research laboratories and on drilling rigs throughout the world. Fann Instrument Company specializes in the design and manufacture of instrumentation for measuring the physical and chemical properties of various fluid properties and especially the measurement of flow and viscosity. Their product line is the most comprehensive offering of instruments and accessories, test kits, and portable laboratories for testing; drilling fluids, completion fluids, fracturing fluids, oil-field cements, and industrial slurries. Fann Instrument Company also provides reagents, supplies, and replacement parts through a worldwide distribution system. Many of the instruments and test kits are designed to conform to the testing standards established by the American Petroleum Institute (API) and published in API SPEC 10, API RP 10B-2, API SPEC 13A, API RP 13B-1, 13B-2, 13D, 13I, 13J, and 13K, and they are suitable for field and laboratory use. Some instruments are designed to meet the requirements of the American Society for Testing and Materials (ASTM) as well as other technical specification groups. Fann is recognized as a leading supplier of sophisticated viscometers and rheometers, which are used in many industries for the measurement of absolute dynamic viscosity of all types of fluids. Fann Direct Indicating Viscometers have been in continuous production for over 60 years. The basic designs have been proven in years of service to be rugged, accurate and dependable. Manufacturing processes have been upgraded to improve productivity and to reduce delivery time while keeping prices and quality in line. No one instrument will solve all fluids measuring problems. The Fann product line includes over fifty different instruments and test kits for fluid analysis, including twelve different instruments for viscosity measurement and characterization of the rheological attributes of fluids.

FANN FAMILY OF VISCOMETERS AND RHEOMETERS Orifice Type Viscometers Marsh Funnel Viscometer is a simple orifice type viscometer, which is used for routine checks of mud viscosity on drilling rigs. It is provided in a rugged plastic construction and is used to measure the relative viscosity of drilling mud compared to the outflow time of water. Direct Reading Viscometers/Rheometers Fann Model 35 Viscometers have been in continuous production for over sixty years. The basic designs have been proven in years of service to be rugged, accurate and dependable. Manufacturing processes have been upgraded to improve productivity and to reduce delivery time without compromising our quality. Fann’s Model 35 Viscometer is the recognized “standard of the industry” for measurement of drilling fluid viscosity. Model 35 Viscometers are Direct Reading, Couette type, coaxial cylinder viscometers which, are used under laboratory and field conditions for determining the rheological characteristics of materials under prescribed conditions of shear stress (torque) and shear rate (RPM). Model 35 Viscometers are available in 6-speed and 12-speed models. All can be used with a wide assortment of accessories including interchangeable bobs, rotors, torsion springs, temperature control vessels and a calibration kit. The Model 280 and 286 Rheometers are also Direct Reading, Couette type, Coaxial Cylinder rheometers. The Model 280 is a two speed, hand‐cranked version, while the Model 286 is a variable speed version with a digital readout for RPM. High Temperature, High Pressure Viscometers The Model 50SL Viscometer is a unique coaxial cylinder type viscometer, which has measuring capability up to 500°F and 1,000 PSIG. It has internal capability for shear rate and temperature programs. The iX77 Rheometer is a High-Temperature, High-Pressure, coaxial cylinder type Rheometer capable of temperatures up to 600°F and pressures up to 30,000 psig. This unit is Modeled after an instrument developed by Sandia National Laboratories. CEMENT TESTING EQUIPMENT HPHT Consistometer Model 275 High-Pressure, High-Temperature Consistometer is a device used to measure cement slurry viscosity or consistency under elevated pressure and temperature conditions. Its primary function is to determine the maximum available pumping time of a cement slurry before the slurry reaches an un-pumpable consistency before setting.    Ultrasonic Cement Analyzers (UCA) The Ultrasonic Cement Analyzer provides a non-destructive method for determining the relative strength development of a cement sample under down-hole temperature and pressure conditions. The theory of operation is based on the correlation between ultrasonic pulse velocity in the cement sample and it’s compressive strength. Pressurized Mud Balance The TRU-WATE Balance
