Barksdale Series UQS7 Ultrasonic Electronic Flow Switch

  • Flow and volume flow monitoring
  • Ultrasonic sensor with digital display
  • Fully configurable via keypad
  • 2 set points and analog output

The UQS7 Electronic Flow Switch from Barksdale provides a highly accurate monitoring and control solution for water-based fluids.

The UQS7 combines two built-in switch points, a 4-20 mA analog output and a digital flow display in a single, compact unit. Ultrasonic sensing technology measures time of flight between two discrete points, assuring highly accurate measurement with low insertion loss as compared to other types of flow sensors.

Setpoints and deadband are easily adjusted by using a built-in, user-friendly menu. UDS7 has an easy to read LED display. Analog transducer outputs are scalable from 25% to 100% of full scale range, providing a high degree of flexibility for a wide range of applications. A 10-bit microprocessor provides built-in self-diagnostics and allows for switch time delays up to 9.9 seconds.
