Gut741 0~15m 0.25% Accuracy Ultrasonic Level Transmitter Manufacturer

The sensor emits ultrasonic pulses that travel to the liquid surface and reflect back. By measuring the "time-of-flight" and factoring in the speed of sound (with automatic temperature compensation), the device accurately calculates the distance to the liquid. Since it never touches the medium, it avoids corrosion and contamination.

The blind zone is the area directly beneath the sensor where it cannot measure accurately (typically 0.25m to 0.5m depending on the range). When installing, ensure the highest possible liquid level does not enter this zone to maintain reliable readings.

No. The GUT741 features built-in temperature compensation. It automatically adjusts the sound speed calculation based on the ambient temperature, ensuring the accuracy remains within 0.25% to 0.5% FS even in changing outdoor environments.

Ultrasonic waves can be absorbed by thick foam or scattered by dense steam, which may lead to unstable readings. If your application involves heavy foam or boiling liquids, please contact our technical team; we may recommend a Radar Level Sensor or a specialized high-power ultrasonic version.

Yes. Because it is a non-contact sensor, it is inherently protected from the medium. For highly aggressive chemical vapors, we offer optional PTFE probes and specialized housing materials to ensure long-term durability.
