Portable transit time flow meter features advanced measurement technology.The TFXP system is said to provide a flow measuring system with unsurpassed accuracy, versatility, ease of installation and dependability. Designed primarily for cleaner liquids, this meter is said to reliably measure liquids containing moderate amounts of suspended solids Suspended solids refers to small solid particles which remain in suspension in water as a colloid or due to the motion of the water. It is used as one indicator of water quality. or aeration aeration /aer·a·tion/ (ar-a´shun) 1. the exchange of carbon dioxide for oxygen by the blood in the lungs. 2. the charging of a liquid with air or gas. aer·a·tion n. . The TFXP portable transit time transit time the time required for ingesta to pass through the gastrointestinal tract; a shorter transit time is seen in conditions associated with gut hypermotility, such as diarrhea. Delayed passage from any cause results in a longer transit time. flow meter flow meter Device that measures the velocity of a gas or liquid. It has applications in medicine as well as in chemical engineering, aeronautics, and meteorology. Examples include pitot tubes, venturi tubes, and rotameters (tapered graduated tubes with a float inside that is is created for long or short term flow measurement surveys on full-pipe liquid systems, according to the manufacturer. It is said to be ideal for verifying calibration of permanently mounted meters of all types, according to the company. The TFXP utilizes two transducers, which function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The flow meter operates by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers. The burst is first transmitted in the direction of fluid flow and then against fluid flow. Since sound energy in a moving liquid is carried faster when it travels downstream than it does upstream, a differential in the times of flight will occur, according to the company. The TFXP features a tactile keypad, a 24hour rechargeable battery, allowing extended operation when AC power is not available, an optional removable 200,000-event data logger and a 128 x 64 pixel backlit An LCD screen that has its own light source from the back of the screen, making the background brighter and characters appear sharper. graphics display, which is all integrated into a rugged, watertight enclosure. The TFXP utilizes the company's proprietary dual time-base time expansion algorithm, advanced DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive and digital cross-correlation. This meter also provides an optional interface that allows operation of the Windows Ultralink software utility which allows simple in-field programming, calibration and software upgrades without connecting any wires. The company's TFXP flow meter measures piping systems l/2" (12 mm) and higher. Included in the TFXP system is the meter, ultrasonic transducer transducer, device that accepts an input of energy in one form and produces an output of energy in some other form, with a known, fixed relationship between the input and output. set, 20' (6 m) transducer interconnection cable, mounting hardware and more.
