Ultrasonic Level Transmitter
The ultrasonic level transmitter is a kind of digital level measuring instrument controlled by microprocessor. Based on non-contact measuring principle, it is compatible with almost all types of mediums. If you are looking for a level measurement solution for liquid and solid materials, the ultrasonic level transmitter is your best choice.
Our HGUL series ultrasonic level meter is available in two-wire, three-wire and four-wire versions.
Two-wire ultrasonic level transmitter: power supply system and signal output system share the two wires
Three-wire ultrasonic level transmitter: independent power supply loop and signal output loop. When powered by 24VDC system, a 3-core cable can be used, and the negative terminals of power supply system and signal output system will share the same cable core.
Four-wire ultrasonic level transmitter: When powered by 220VAC system or by 24VDC system with completely isolated power supply loop and signal output loop, a 4-core cable shall be used. Whether it is DC or AC power supply, the output is 4~20mADC. High and low switch-outputs are available.
Measuring Range: 0-50m
The ultrasonic level transmitter is built for challenging corrosive mediums and various chemicals. The highly accurate sensor is controlled by PLC system and supports 4-20mA signal output.
