Liquid Flow Ultrasonic Transmitter

The AquaTrans AT868 Liquid Flow Ultrasonic Transmitter combines state-of-the-art flow measurement capabilities with a low-cost transmitter package that can be mounted directly at the process measurement point.

It can be installed directly at the process measurement point. It is designed for water and wastewater applications in full pipelines.

The all-digital AquaTrans AT868 has no moving parts and requires minimal maintenance.

The on-board microprocessor utilizes patented Correlation Transit-Time™ technology for long-term drift-free operation. Automatically adjusts to changing fluid characteristics and dynamically configurable operating software simplifies programming.

Transit-Time Flow

Measurement Technology

Transit-Time technology uses a pair of transducers, each of which sends and receives a coded ultrasonic signal through the fluid.

As the fluid flows, the signal transmission time in the downstream direction is shorter than in the upstream direction; the difference in transmission time is proportional to the flow rate.

The AquaTrans AT868 measures this time difference and uses programmed pipe parameters to determine flow rate and direction.
