Ultrasonic Level Transmitter

TLTV1000A5

The TLTV1000A5 Ultrasonic Level Transmitter is a high-performance non-contact liquid level measurement device designed for industrial tanks, reservoirs, and process vessels. Using ultrasonic time-of-flight technology, it measures the liquid level by analyzing the travel time of sound waves reflected from the liquid surface. With advanced diagnostics, multiple display modes, and built-in temperature compensation, the transmitter delivers accurate and stable level monitoring even in fluctuating process conditions.
