DYNASONICS
Frequently asked questions
Common questions about DYNASONICS from 3G Electric.
What is the difference between Dynasonics Doppler and transit-time ultrasonic flowmeters?
Dynasonics offers both Doppler and transit-time ultrasonic flowmeters. Doppler meters, such as the dedicated Doppler ultrasonic meters (e.g., DDFXD2-ENNA-NN), are designed for liquids with sufficient suspended solids or bubbles to reflect the ultrasonic signal. They measure flow rates as low as 0.15 fps with +/-2% full scale accuracy. Transit-time meters, like the portable clamp-on models (e.g., D5-C-E2-AD-S-A-K-E-D), work with clean liquids and achieve +/-0.5% accuracy. The choice depends on the fluid characteristics and required accuracy. Both types are non-invasive and clamp onto the outside of pipes.
What pipe sizes do Dynasonics portable clamp-on ultrasonic flowmeters support?
Dynasonics portable clamp-on ultrasonic flowmeters for water, such as the D5-C-E2-AD-S-A-K-E-D and D5-C-H2-AD-S-A-K-E-D, are designed for pipe sizes from 1/2 inch to 12 inches. These meters use clamp-on transducers that mount on the exterior of the pipe, so they do not require pipe modification or process shutdown. The aluminum housing and 240V AC operation make them suitable for temporary or permanent installation in various water flow monitoring applications.
What is the accuracy of Dynasonics ultrasonic flow meters?
Accuracy varies by model. Dynasonics Doppler flow transducers and dedicated Doppler ultrasonic meters, such as the 7HU43, DDFXD2-ENNA-NN, and DDFXD2-ANNA-NN, have an accuracy of +/-2% full scale. Portable clamp-on ultrasonic flowmeters for water, including the D5-C-E2-AD-S-A-K-E-D, D5-C-H2-AD-S-A-K-E-D, and similar models, offer +/-0.5% accuracy. The appropriate model depends on the application requirements and fluid conditions. All models provide digital display for local readout.
What is the Dynasonics output module D020-1045-100 used for?
The Dynasonics output module D020-1045-100 (SKU 5XPN4) is an accessory for ultrasonic flowmeter detectors. It interfaces with compatible Dynasonics ultrasonic meters, specifically the 5XPN0 and 5XPN1 models, to provide signal output functionality for flow measurement. This allows the meter to transmit flow data to external systems such as data loggers, PLCs, or control panels. The module is used when a direct output signal is required for integration with process control or monitoring equipment.
What temperature range do Dynasonics ultrasonic flow meter transducers operate in?
The Dynasonics ultrasonic flow meter transducer DT94-020-N000-N (SKU 5XPN2) operates in temperatures from -40°F to 185°F. This wide range allows the transducer to be used in various industrial environments, including outdoor installations and processes with elevated fluid temperatures. The response time for this model is 6 to 60 seconds, and it is designed for pipe sizes around 1 inch. Other Dynasonics models may have different temperature specifications, so always verify the specific model's ratings for your application.
Can Dynasonics flow meters be used for both temporary and permanent installations?
Yes, Dynasonics portable clamp-on ultrasonic flowmeters, such as the D5-C-E2-AD-S-A-K-E-D and D5-C-H2-AD-S-A-K-E-D, are suitable for both temporary and permanent flow measurement. Their clamp-on design allows for non-invasive installation without cutting into pipes, making them ideal for temporary monitoring or troubleshooting. For permanent installations, they can be mounted and left in place. Dedicated meters like the DDFXD2 series are typically used for permanent installations where continuous flow monitoring is required. The choice depends on the specific application and duration of monitoring needed.
