Product Details

Intelligent 3 wire series Ultrasonic Level Meter Compact Type for Liquid and Solids

3-wire series of ultrasonic level meter is actually four wire system, its power supply (DC24v only) and the signal output (DC4-20 mA) loop is separate, each of them use two lines, when they were connected to negative side, they usually use three lines. Its advantage is transmitted power is larger. Ultrasonic level meter's ultrasonic sensor is fully closed structure, the structure of the integrated sensor shell's optional materials have: ABS, PVC, PTFE. PTFE is resistant to strong acid, strong alkali, organic solvent corrosion, fully adapt to all kinds of measured medium, three-wire system of ultrasonic level meter's maximum span is 40 meters, having the characteristics of small blind area, large range of advanced technology.

We provide serial crusts for customer’s choice.

Intelligent 3 wire series Ultrasonic Level Meter Compact Type for Liquid and Solids Features:

1. Can be flexibly customized according to customer demand.

2. The level meters with HART® 7 Communication Protocol which have been passed the tests by the HART certification laboratory.

3. With the patents of Smart echo processing technology to ensure the accuracy and stability.

4. Patented ultrasound probe structure, ultra short blind range, high sensitivity, built-in full range of automatic temperature compensation.

5. Continuous level measurement, the maximum range of up to 40m.

6. HART, MODBUS protocol communication is optional.

7. Ultrasonic probe using PVC or PTFE materials for a variety of corrosive conditions, sanitary type is optional.

8. Easy to install, operate and maintain.
