Ultrasonic flow meter measure fluid velocity by passing high-frequency sound waves along the fluid flow path. Katronic ultrasonic gas flowmeters can measure a wide variety of different gases in pipes of up to 1500 mm in diameter. Condition: An ultrasonic flow meter construction can be done by using upstream and downstream transducers, sensor pipe and reflector. With no moving parts, the E-Series Ultrasonic meter is virtually maintenance-free and has greater extended low flow accuracy compared to mechanical meters. (5) Ultrasonic flowmeters for partially full pipes and river channels that combine liquid level measurement and average velocity measurement. Design of Ultrasonic Flow Meters. Ultrasonic sensing uses the time of flight (TOF) of an ultrasonic wave within any liquid or gas medium and its dependency on the flow rate to measure and calculate volume flow. DN1000 / 40", up to ASME Cl 4500; 3 x 420 mA, HART 7, Modbus, FF, Profibus-PA/DP The working principle of ultrasonic flow meter is, it uses sound waves to resolve the velocity of a liquid within a pipe. The basic principle of operation employs the Doppler Effect which is the term used to refer to a shift in frequencies when an ultrasonic signal is reflected by discontinuities in the form of suspended particles or bubbles in motion. mL/min GPH; 10 - 10000.158 - 158.5: PSI Bar; 200: 13.78: Pipe Sizes; barb, M/NPT, PVC slip: MS6. Transmit mode When in transmit mode, an oscillating electrical current creates a vibration in the piezoelectric crystal, and an ultrasonic wave is sent through the flowing fluid. There is no pressure loss. We offer two standard air coupled sensors ideally suited for this application.

With the versatile U1000 V2 flow meter from GF Piping Systems you can accurately measure flow contactless without affecting the production process or the end-product quality. For water flow measurement, it is recommended to use 1MHz. Some design allows measurement to be made external to the pipe, while other requires that the sensor be in contact with the flow stream. The ultrasonic flow meters are the key to optimising operating costs. Utilities can now improve water- and heat-metering accuracy by an order of magnitude, while operating for up to 20 years on a single "A"-size battery with the MAXREFDES70# ultrasonic flow meter reference design from Maxim Integrated Products. Doppler Flow meter use reflected ultrasonic sound to measure the fluid velocity. Called permanent due to the requirement for a power supply. Industrial; Municipal; S6A. Having measured the downstream and upstream transit times of the transducers, the Wireless Waterflow Monitoring System measures the water flow within the pipe. Doppler flow meters TRANSIT TIME FLOW. A third ultrasonic flow meter employs cross-correlation between upstream and downstream transducer pairs to compute flow. We will discuss both types in detail. One of the more common purposes of an ultrasonic flow meter is to measure the velocity of a fluid in order to calculate the volumetric flow rate of a medium through a tube. These applications are illustrated based on operating experience with the Instromet 3 path and 5-path Q.Sonic custody transfer flow meter, however, many of these issues may be generalized to devices manufactured by others. to enable the meter to measure and correct for flow transients across the horizontal plane, it allowed for 3 dimensional measurements. Two major sub-types of ultrasonic flow meters exist: Doppler and transit-time.

Ultrasonic flow meters are compact with a large display that is clear and easy to read. The non-contact ultrasonic flow meter is a non-invasive flow meter available in two formats: transit time and doppler Of course, this is not big difference This easy-to-use clamp on flow meter comes standard with a rugged, waterproof carrying case that allows the display, transducers, and cables to be easily transported between measuring locations Kit includes Flow Meter, Small Multiple traverse Ultrasonic Flow meter. The working principle of the ultrasonic flow meter is, it uses sound waves to determine the velocity of the liquid in the pipe. Measurement is not possible when there are many air bubbles. The Panametrics DigitalFlow GM868 is a general-purpose gas flow meter designed to measure gas flow in pipes or ducts. The 200kHz transducers are primarily used for gas flow measurement. 2. Types of Ultrasonic Flow Meter InstallationsPortable Ultrasonic flow meterClamp on fix ultrasonic flow meterIn Line Ultrasonic Flow MeterInsertion Ultrasonic Flow MeterOpen Channel Ultrasonic Flow Meter Select a meter design that employs a multi-path design that properly characterizes the flow profile and can report whether swirl and/or asymmetry are present via meter diagnostics. Gas Flow Measurement For gas flow meter applications the design, selection and use of high quality matching layers is particularly important to ensure high sensitivity and optimal bandwidth. Temperature Range. Fluid motion influences the propagation of these sound waves, which may then be measured to infer fluid velocity. This model was discontinued out of Japan. The fixed ultrasonic flow meter is mainly installed in a fixed position, and can measure the flow of liquid in a fixed pipeline for a long time without interruption, while the portable flow meter is mobile and is mainly used for liquids in a pipe for temporary measurement UltraFlo UFD3 Ultrasonic Clamp-On Flow Meter Source from Dalian Taosonics Instrument Co Product No A special shape of pipe is designed, accompanied with customized transducers. For Doppler ultrasonic flow meters, be sure that the fluid adequately reflects ultrasonic waves, because the flow meter will not operate without a reflected ultrasonic signal. Design of the dToF type ultrasonic water meter. ScioSense solutions for ultrasonic flow meters measure water, heat and gas flows. Liquids that have a large solid content will cause malfunctions. TransPort Family of Portable Liquid Flow Meters - The portables line from Panametrics, a Baker Hughes business, offers both ultrasonic liquid and gas clamp-on flow meters: The TransPort PT878GC for gas; and the TransPort PT900 for liquid..

Using ultrasonic waves, the flow volume of a wide variety of gases and liquids can be measured reliably independent of electrical conductivity, pressure, temperature or viscosity. A multiple-transverse configuration consists of two transducers mounted on the pipe so that the signal DUC - Quick-Mount Clamp-on Ultrasonic Flow Meter for Liquids. The ow speed is detected at different distances. Time-of-flight w/DSP (Transit Time Principle) Flow Velocity Range. v = flow velocity c = speed of sound Thus, Flow Velocity (v) = (L/dt) c (2) As shown in the above equation, the time difference of the ultrasonic signals is proportional to the flow velocity in the pipe.
