Panametrics liquid flow ultrasonic transmitter Applications The DigitalFlow XMT868i liquid flow transmitter is a complete ultrasonic flow metering system for measurement of: • Economical, nonintrusive flow measurement • Hydrocarbon liquids • Liquefied natural gas (LNG) • Crude oil • Lubricating oils • Diesel fuel oils • Solvents • Water and wastewater • Hot/chilled water • Chemicals • Beverages • Other liquids • Hazardous (classified) location certification • Simple setup and installation • Suitable for a wide range of pipe sizes and materials • Two-channel/two-path version available • Energy measurement option • Large backlit LCD display • Velocity, volumetric and energy flow r

Panametrics liquid flow ultrasonic transmitter The DigitalFlow XMT868i ultrasonic flow transmitter combines state-of-the-art flow measurement capability with a low-cost transmitter package that can be installed right at the process measurement point. The XMT868i carries appropriate certification for installation in hazardous (classified) locations commonly found in petrochemical and chemical processing environments. The all-digital XMT868i has no moving parts, requires minimal maintenance and provides long-term, drift-free operation. An onboard microprocessor provides exclusive digital...

Flowmeter transducers DigitalFlow XMT868i flow transmitter uses transit-time flow measurement technique Fluid flow Flowmeter transducers Ultrasonic signal path Fluid flow Ultrasonic signal path Transit-time flow measurement technique In this method, two transducers serve as both ultrasonic signal generators and receivers. When mounted on a pipe, they are in acoustic communication with each other, meaning the second transducer can receive ultrasonic signals transmitted by the first transducer and vice versa. In operation, each transducer functions as a transmitter, generating a certain...

XMT868i specifications Operation and performance Fluid types Acoustically conductive fluids, including most clean liquids, and many liquids with entrained solids or gas bubbles. Maximum void fraction depends on transducer, interrogation carrier frequency, path length and pipe configuration. Pipe sizes • Clamp-on transducers: 0.5 in to 300 in (12.7 mm to 7.6 m) and larger • Wetted transducers: 1 in to 200 in (25.4 mm to 5 m) and larger Pipe wall thickness Up to 3 in (76.2 mm) Pipe materials All metals and most plastics. Consult Panametrics for concrete, composite materials, and highly...

Additional options PanaView™ PC interface software The DigitalFlow XMT868i communicates with a PC through a serial interface and Windows® operating systems. Consult the manual for details on sites, logs and other operations with a PC. XMT868i application notes in brief. Ultrasonic flowmeter saves money over mag meter A sewerage/wastewater facility found that installing a Panametrics clamp-on ultrasonic flowmeter offered excellent performance and accuracy and was far less expensive than installing a new mag meter. When comparing cost of a new 30 in (750 mm) mag meter to be installed on their...
