AUL730 Series
The AUL730 Series is a fixed-mounted Ultrasonic Level Transmitter that can be fixed in the air and used for non-invasive measurement. Our microprocessor-based, user-friendly, field-programmable level measurement technique allows no interruption of the process level and has low installation costs.
Features
- Simple set-up and operation
- Fast and simple to install and configure
- Loop-powered 4-20 mA output with HART signal
- Low cost of installation and commissioning
- Non-contact level measurement
- Exclusive sensor for level transmitter
- Response time less than 1 second
