Panametrics' AquaTrans™ AT868 ultrasonic flowmeter combines state-of-the-art flow measurement capability with a rugged, low-cost transmitter package that can be installed right at the process measurement point. It is designed specifically for municipal applications such as water, wastewater and sewage. Setup and service are easily accomplished by using the AT868 transmitter’s internal keypad or by connecting the AT868 to a laptop PC and using GE Panametrics instrument interface software.

Accuracy is typically one to two percent of reading with clamp-on transducers, and better than one percent with wetted transducers. Flow measurement range is 0.1 to 40 ft/s (0.03 to 12.2 m/s), for a turndown ratio of 400 to 1. Measurement is obstructionless, causing no pressure drop and is noncontaminating.
