Fixed-installation ultrasonic flowmeter for pipes is a precise and versatile solution for continuous measurement of flow rate and flow velocity in water and other liquids. With an accuracy of 1% and compatible with pipes from 25 to 1200 mm, it allows sensors to be installed externally without cutting the pipe, ideal for processes where flow cannot be interrupted or hygiene cannot be compromised, such as in the food industry.

This flowmeter supports measurement by V method (reflection) or Z method (direct), adapting to different mounting conditions. Its intuitive menu lets you configure parameters like diameter, material or wall thickness, and displays the exact sensor installation distance to ensure reliable measurements.

Includes 4-20 mA outputs, relay, pulse (OCT), RS-232 and RS-485, facilitating integration into control systems. It also logs daily, monthly and annual histories, enabling detailed tracking of consumption and system performance.

Continuous inline flow control with the TDS 75 Flowmeter without cutting the pipe

The TDS 75 Ultrasonic Flowmeter is designed for applications where service continuity and process integration are critical. By using external transducers, the measurement is performed without mechanical intervention on the pipe, minimizing leakage risks and reducing downtime for maintenance or commissioning.

The system can be configured in the field to suit installation conditions, selecting between reflection measurement (V method) or direct measurement (Z method). This flexibility helps optimize signal quality and reading reliability depending on pipe diameter, material and installation geometry.

Key features of the ultrasonic flowmeter for pipes

  • External, non-intrusive installation: sensors are mounted on the pipe wall, avoiding penetrations and reducing interventions.
  • Continuous measurement for operational monitoring and consumption/production control.
  • Automation integration via 4-20 mA analog output, pulse output (OCT), relay and serial communications (RS-232 / RS-485) for process controllers.
  • Alarm management by limits: monitoring of minimum/maximum flow with configurable output activation.
  • Recording and historical inquiry via date-based totalizer for daily, monthly and yearly tracking.
  • Field configuration from the keypad and device menu to enter pipe data and verify signal quality.

Applications of the flowmeter for water in industrial installations

  • Flow measurement and control in process water networks and utility systems.
  • Supervision in distribution systems and pumping stations.
  • Integration into control panels, PLCs and SCADA systems for performance monitoring.
  • Environments with hygiene requirements where non-intrusive measurement is prioritized.
