SITRANS Probe LU has a 2-wire loop powered ultrasonic transmitter for volume, level and flow monitoring of liquids in storage vessels, simple process and open channels. It is suitable for monitoring water and wastewater and also chemical storages. It measures 6 or 12m. With automatic False-Echo Suppression for fixed obstruction resistance, and a better signal-to-noise ratio and improved accuracy of 0.15% of range or 6mm. It also includes Sonic Intelligence® signal handling from the field-proven Probe and integrates innovative echo processing features and the latest micro-processor and communications technology also having HART or PROFIBUS PA communication options for best results.
