TRANSPORT® PT868 FLOWMETER
OPTIONS AND SPECIFICATIONS
TRANSPORT FLOWMETER OPTIONS, ACCESSORIES AND SPECIFICATIONS. The TransPort PT868 Portable Liquid Flowmeter is a complete portable ultrasonic flow metering system with options and accessories to meet all your flow metering needs. It’s the only ultrasonic flowmeter that is available with two built-in measurement technologies, the standard transit-time mode and the optional TransFlection® mode, to cover the spectrum from ultraclean water to difficult multiphase flow applications. Other options and accessories include: single-channel and two-channel models; a variety of wetted and clamp-on transducers, clamping fixtures and flowcells; resistance temperature devices (RTDs) and other accessories for energy flow measurement; an ultrasonic pipe-wall thickness transducer; a thermal printer with accessories; custom PC-interface software; and a variety of power supplies and accessories.
STANDARD MODEL PT868 WITH TRANSIT-TIME MODE.
The standard PT868 comes configured for single-channel, transittime mode flow metering. Transittime is a very versatile method that is suitable for most clean liquids, and the TransPort flow-
meter expands its use to include many fluids with entrained solids and gas bubbles. To extend the benefits of the transit-time method to more difficult applications, the PT868 uses a patented acoustic signal-coding technique that greatly increases its signal-to-noise ratio. This allows the PT868 to make accurate, drift-free flow measurements in many two-phase flows containing gas bubbles, liquid droplets, or entrained solids where conventional transit-time meters fail.
MODEL PT868R WITH NEW
TRANSFLECTION MODE. The new PT868R is a dual-mode flowmeter featuring both transittime and TransFlection mode flow metering. Panametrics’ new TransFlection ultrasonic flow metering technology is available exclusively from Panametrics. This patented technique was developed for flow measurements in multiphase fluids such as raw sewage, sludge, slurries, tar sands, oil-water-gas mixtures, acoustically attenuating liquids, and other demanding applications.
DUAL-CHANNEL MODEL
2PT868. The TransPort 2PT868 flowmeter is also available as a two-channel model for flow applications requiring two simultaneous flow measurements with

one meter. The two measurement points can be on different pipes, or at two locations on the same pipe. Either clamp-on or wetted transducers can be used at either location. The dualchannel TransPort flowmeter can also be set-up for two-path flow measurement at a single location for enhanced accuracy. No matter how it’s used, this model continuously measures the selected flows on both
channels, as well as the sum, the difference, and the average of those two channels.

FLOW TRANSDUCERS, CLAMPING FIXTURES, AND
FLOWCELLS. With over 20 years experience in ultrasonic flow measurement, Panametrics has what you need for virtually any flow measurement application. The TransPort flowmeter can be used with all Panametrics ultrasonic liquid flow transducers, clamping fixtures and flowcells.
Small-pipe clamping fixture with nonintrusive transducers ensures no leaks, corrosion or contamination.
A wide variety of clampon and wetted transducers are available with different operating frequencies, materials of construction, operating temperatures, sizes, area classifications (standard or hazardous), and operating principles (e.g., shear wave and longitudinal wave) to meet your requirements.
To hold clamp-on transducers in contact with the pipe, a variety of clamping fixtures are available to accommodate different pipe and transducer sizes, and the desired fixture attachment method (e.g., chain; metal strap; VELCRO® straps; and magnetic, bolt-on, or weldable steel yoke with metal banding). Our universal clamping fixture includes ruled slide-tracks to simplify transducer spacing for accurate flow measurements. There’s even a special small-pipe clamping fixture with miniaturized transducers to
simplify the flow measurements on 1/2- to 2-inch lines.
The TransPort PT868 flowmeter can also be used with flowcells or spool-pieces— precision-machined pipe sections with wetted transducers already in place—for improved accuracy or special situations such as flow measurement in very small tubing (e.g., 1/8 inch). For wetted transducer accuracy with portability, Pan-Adapta® precision-machined pipe plugs can be threaded into pipe couplings or tees, letting you install and remove wetted transducers without interrupting the process or emptying the pipe.
Please contact Panametrics for assistance in choosing the best transducers, fixtures, or flowcells for your application.
Dual RTD transmitter and RTDs.
OPTIONAL ENERGY MEASUREMENT EQUIPMENT.
The TransPort flowmeter combines proven ultrasonic flow measurement with precise RTD temperature measurement to determine the energy flow rate in liquid heating and cooling systems. The TransPort flowmeter, with optional energy equipment, extends the benefits of ultrasonic flow measurement to energy measurement. These benefits include measurement of flow
and temperature without pipe penetration for pipes from 1/2 to 200 inches in diameter with liquid temperatures from –20°C to 260°C. The TransPort flowmeter is designed for energy measurement in water and water/glycol systems. Consult Panametrics for use with other liquid systems.
Every TransPort flowmeter comes equipped with a built-in 16-V supply for loop-powered RTD temperature sensors, as well as all necessary circuitry and software to make energy flow rate measurements. To complete the system, Panametrics offers a variety of optional components. These include clampon and wetted RTD temperature sensors and a dual RTD transmitter that directs loop power from the TransPort flowmeter to the RTDs. This transmitter accepts raw RTD inputs and provides
4- to 20-mA temperature inputs back to the TransPort flowmeter. These components can be purchased separately, or as part of a turnkey solution.
OPTIONAL PIPE WALL THICKNESS GAGE
TRANSDUCER. Pipe-wall thickness is a critical parameter used by the TransPort flowmeter for clamp-on flow measurements. The more accurately the pipe-wall thickness is known, the more accurate the flow measurements can be. Panametrics offers a thickness gage option that allows accurate wall thickness measurement from outside the pipe. The thickness gage option includes an ultrasonic thickness transducer, transducer cable, metric or nonmetric calibration block, and a bottle of transducer couplant.
