Liquid Flow Ultrasonic Transmitter

Transducers

The AquaTrans AT600 liquid flow ultrasonic transmitter combines state-of-the-art flow measurement capability with a low-cost transmitter package that can be installed right at the process measurement point. It’s designed specifically for water and wastewater applications in full pipes. The all-digital AquaTrans AT600 has no moving parts and requires minimal maintenance. An onboard microprocessor uses patented Correlation Transit-Time™ technology for long-term, drift-free operation. Automatic adjustment to changing fluid properties and dynamically configured operating software simplify programming.

Transit-Time Flow Measurement

In this method, two transducers serve as both ultrasonic signal generators and receivers. They are in acoustic communication with each other, meaning the second transducer can receive ultrasonic signals transmitted by the first transducer and vice versa. In operation, each transducer functions as a transmitter, generating a specified number of acoustic pulses, and then as a receiver for an identical number of pulses. The time interval between transmission and reception of the ultrasonic signals is measured in both directions. When the liquid in the pipe is not flowing, the transit-time downstream equals the transit-time upstream. When the liquid is flowing, the transit- time downstream is less than the transit-time upstream. The difference between the downstream and upstream transit times is proportional to the velocity of the flowing liquid, and its sign indicates the direction of flow.

Easy Four Step Installation

Step #1: Install straps onto pipe.

Step #2: Put clamp-on fixture on pipe and move straps onto sides of fixture.

Step #3: Open fixture to set spacing.

Step 4: Set spacing and lock fixture with transducers onto pipe.

Clamp-On Transducers

Clamp-on transducers oer maximum convenience, exibility and a low installation cost compared to traditional ow metering technologies. With proper installation, clamp-on transducers provide better than 1% of reading accuracy in most applications.

Vitality™ Software (Optional)

The AquaTrans AT600 can communicate with a PC via our Vitality interface program. Consult the manual for details on sites, logs, and other operations with a PC.

Specifications

Overall Operation and Performance

Fluid Types

Liquids: acoustically conductive fluids, including most clean liquids, and many liquids with small amounts of entrained solids or gas bubbles

Flow Measurement

Patented Correlation Transit-TimeTM mode

Pipe Sizes

0.5 to 300 in. (15 to 7600 mm)

Pipe Materials

All metals and most plastics. Consult Baker Huges for concrete, composite materials, and highly corroded or lined pipes.

Accuracy

• ±1% of reading in application, ≥2 in. (50 mm) pipe and >1 ft/s (0.3 m/s) velocity

• ±2% of reading in application, <2 in. (50 mm) pipe and >1 ft/s (0.3 m/s) velocity

• ±0.5% in field calibration

Installation assumes a fully developed, symmetrical flow profile (typically 10 diameters upstream and 5 diameters downstream of straight pipe run). Final installation accuracy is a function of multiple factors including fluid, temperature range, pipe centricity and others.

Calibration

All meters are water calibrated and delivered with a traceable calibration certificate.
