Q1: What is the blind zone of a digital ultrasonic level transmitter?
A1: The blind zone of a digital ultrasonic level transmitter is the minimum distance where the sensor cannot provide accurate level measurement. It is typically 0.25–0.6m, depending on the sensor model. Maintaining a proper distance between the sensor and liquid surface helps ensure reliable and accurate ultrasonic level measurement.
Q2: What is an ultrasonic water level sensor?
A2: An ultrasonic water level sensor is a non-contact measuring device that uses ultrasonic waves to detect the distance between the sensor and the water surface. It calculates the water level by analyzing the reflected signal, providing accurate and reliable water level measurement for tanks, rivers, reservoirs, and industrial applications.
Q3: Can a digital ultrasonic level sensor measure wastewater?
A3: Yes, a digital ultrasonic level sensor is suitable for wastewater measurement. Its non-contact ultrasonic technology allows reliable level monitoring in sewage tanks, wastewater treatment systems, and industrial drainage applications without direct exposure to contaminated liquids. Proper installation helps ensure accurate and stable measurements.
Tips: What output signals does the ultrasonic water level sensor support?
The ultrasonic water level sensor supports 4–20mA and RS485 output, allowing easy integration with PLCs, control systems, and remote monitoring platforms for industrial automation and real-time level monitoring.
