Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang DYNASONICS dari 3G Electric.
What is the difference between DYNASONICS Doppler and transit-time ultrasonic flowmeters?
DYNASONICS Doppler flowmeters use the Doppler shift principle, where ultrasonic signals reflect off particles or bubbles in the fluid. They are suitable for slurries, aerated liquids, or fluids with suspended solids, with a typical accuracy of ±2% full scale. Transit-time flowmeters measure the time difference between upstream and downstream ultrasonic pulses, requiring clean, particle-free liquids, and offer higher accuracy up to ±0.5%. The choice depends on fluid characteristics: Doppler for dirty or aerated flows, transit-time for clean liquids.
What pipe sizes are compatible with DYNASONICS clamp-on transducers?
DYNASONICS clamp-on transducers cover a wide range of pipe sizes. For example, the DT94-020-N000-N model fits pipes from 1 inch to 1 inch, while the DT95-020-N000-N fits 0.25 inch to 1 inch. The portable flowmeter models D5-C-E2-AD-S-A-K-E-D and D5-C-B2-AD-S-A-K-E-D accommodate pipes from 1/2 inch to 12 inches, and the D5-C-T2-AD-S-A-K-E-D extends to 48 inches. The DTTR-020-N000-N transducer handles pipes from 2 inches to 98 inches. Always verify the specific model's pipe size range in the datasheet.
What is the operating temperature range for DYNASONICS ultrasonic transducers?
DYNASONICS transducers, such as the DT94-020-N000-N and DT95-020-N000-N, are rated for operating temperatures from -40°F to 185°F (-40°C to 85°C). This range covers most industrial water and process fluid applications. For extreme temperature environments, consult the specific model's datasheet, as some transducer variants may have different limits. The electronics in the flowmeter units may have additional temperature constraints, typically specified in the user manual.
Can DYNASONICS portable clamp-on flowmeters be used for permanent installation?
Yes, DYNASONICS portable clamp-on flowmeters, such as the D5-C series, are designed for both temporary and permanent installation. They feature aluminum enclosures rated for industrial environments and operate on 240V AC. The clamp-on design allows non-invasive mounting on existing pipes without cutting or welding, making them suitable for permanent monitoring in applications where pipe modification is not feasible. However, for outdoor or harsh environments, verify the enclosure's IP rating for weather resistance.
What output signals are available on DYNASONICS flow transducers?
DYNASONICS flow transducers typically provide a 4-20 mA analog output, as seen in the DTTR-020-N000-N model with ±1% accuracy. Some models also include LCD digital displays for local readout. The portable flowmeters may offer additional outputs such as pulse or frequency signals for integration with PLCs or data loggers. Check the specific model's specifications for available output types and compatibility with your control system.
