Ultrasonic measurement travel time principle Prosonic FMU30
Economical all-round level measuring instrument for level measurement of liquid and solid bulk materials
Applications include wastewater treatment plants, process water storage tank loading, and level monitoring of storage tanks and buffer tanks. FMU30 provides mature software algorithms, four lines of plain text display reminder and alarm information to ensure fast fault response, display simultaneously displays the envelope, and directly displays the analysis results on site to ensure rapid and accurate fault diagnosis. |
Advantage
- Four lines of plain text display, menu-guided on-site operation, quick and easy instrument commissioning, available in 7 languages
- On-site envelope display for simple instrument troubleshooting
- Linearization function (up to 32 points) converts measured values into length, volume or flow to any unit
- Non-contact measurement to minimize maintenance services
- Thread G11⁄2 or 11⁄2 NPT or more can be installed
- Built-in temperature sensor to automatically correct the speed of sound affected by temperature
