Why Choose ATLAS Ultrasonic Flow Meters?

ATLAS ultrasonic flow meters use acoustic measurement to monitor flow in suitable liquid applications. Options for conductive and non-conductive liquids and forward/reverse flow measurement address different needs in water and industrial process lines.

Steel bodies and optional 304 or 316 stainless steel in the flanged range allow mechanical selection for installation and fluid conditions. Protection, temperature and measurement performance are matched to the selected sensor–transmitter combination. Flanged and external clamp-on model specifications are not interchangeable.

Analogue, pulse and digital communication options support measurement transfer to compatible automation or acquisition systems. Modbus and other interfaces are determined by the order configuration; communication hardware needed for remote reading is selected separately. The measuring point can therefore be designed to fit the facility’s monitoring architecture.

Key benefits

  • Ultrasonic measurement for suitable conductive and non-conductive liquids.
  • Bidirectional flow monitoring and application-specific body selection.
  • Automation connection through the selected outputs and communication hardware.

It offers remote management and monitoring capabilities via a wireless communication infrastructure. Thanks to its IP68 protection rating and robust design, it ensures long-lasting performance in industrial applications.
