Ultrasonic Level Transmitter

TLTV1000A4

The TLTV1000A4 Ultrasonic Level Transmitter is a reliable remote-type non-contact level measurement solution designed for monitoring liquid levels in industrial tanks, reservoirs, and water treatment systems. The transmitter uses ultrasonic time-of-flight technology to determine the distance between the sensor and the liquid surface by measuring the travel time of ultrasonic waves. With intelligent signal processing, temperature compensation, and advanced diagnostics, the TLTV1000A4 ensures stable and accurate level monitoring in industrial environments.

  • Accurate non-contact liquid level measurement with minimal maintenance
  • Reliable readings even when liquid levels fluctuate rapidly
  • Built-in temperature compensation for improved accuracy
  • Remote sensor installation allows flexible mounting in difficult locations
  • Integrated diagnostics and alarm current output for system monitoring
