Description
Product Name: AT868W1-1-1-1 GE Output module
Product details:
The GE Panametrics AquaTrans AT868 is a loop-powered, cost-effective, and highly reliable ultrasonic liquid flow transmitter. Designed primarily for water and wastewater applications in full pipes, it combines state-of-the-art ultrasonic flow measurement with a low-profile transmitter package that can be installed directly at the process measurement point.
Utilizing patented Correlation Transit-Time™ technology, it provides drift-free, precise measurements without any moving parts, drastically minimizing maintenance overhead. It supports both non-intrusive clamp-on transducers (which eliminate the need to cut pipes or shut down processes) and wetted transducers (for higher baseline accuracy).
Product Parameters (Specifications)
| Parameter | Specification Details |
| Measurement Mode | Patented Correlation Transit-Time™ mode |

| Display | 2-line x 16-character backlit LCD display (configurable sequence) |
| Keypad | 6-button internal tactile keypad for local programming |
| Power Supply Options | Standard: 85 to 265 VAC, 50/60 Hz
Optional: 12 to 28 VDC (±5%) |
| Power Consumption | 20 Watts maximum |
| Operating Temperature | -10°C to 55°C (14°F to 131°F) |
| Outputs | Two 4-20 mA analog outputs; Two frequency/totalizer pulse outputs |
| Pipe Size Range | Clamp-on: 0.5 in to 300 in (12.7 mm to 7.6 m) and larger |
| Accuracy | Wetted: Better than ±1% of reading
Clamp-on: Typically ±1% to 2% of reading |
| Repeatability | ±0.2% of reading |
Product Advantages
- Non-Intrusive Design (Clamp-On): Sensors can be clamped onto the outside of the pipe. This avoids pipe cutting, process downtime, leakage risks, and pressure drops.
- No Moving Parts: Zero mechanical wear ensures long-term calibration stability and eliminates regular maintenance costs.
- Dual-Channel Flexibility: The 2-channel version allows you to track flow in two different pipes simultaneously, or use a two-path layout on a single pipe to minimize turbulence distortion and boost accuracy.
- Digital Signal Processing (DSP): The patented technology allows the meter to handle tough acoustic conditions, automatically adapting to changing fluid properties or slight gas/solid entrainments.
- Highly Versatile: Performs seamlessly across a massive range of pipe materials (including lined pipes like concrete or plastic) and line sizes.
Product Applications
The AT868 is optimized for municipal, industrial, and building utility systems monitoring clean or slightly dirty liquids:
- Water Management: Potable/drinking water distribution, raw water tracking.
- Wastewater Treatment: Sewage, treated effluents, and discharge water monitoring.
- HVAC Systems: Cooling and heating water loop monitoring (can be paired with temperature sensors for energy calculation).
- Industrial Utilities: Process water, boiler feed water, and irrigation networks.
- Acoustically Conductive Liquids: Most clean chemicals, light oils, and water-based mixtures.
Important Considerations & Precautions (Precautions)
- Straight Pipe Run Requirements: To achieve the stated accuracy, ensure a fully developed flow profile. This typically requires a minimum of 10 diameters upstream and 5 diameters downstream of straight, unobstructed pipe away from valves, pumps, or bends.
- Full Pipe Condition: The system relies on ultrasonic signal transit. The pipe must be completely full of liquid at all times; empty or partially full pipes will cause error codes or signal loss.
- Acoustic Couplant: For clamp-on installations, always apply a generous, uniform layer of ultrasonic couplant grease between the transducer face and the pipe wall to eliminate air gaps.
- Air Bubbles & Solids: While highly capable, severe aeration (heavy air bubbles) or excessive solid slurry content can block the ultrasonic signal path.
- Wiring Safety: Ensure the power supply is completely turned off before opening the IP66 enclosure or making changes to the internal terminals.
