CONTREC 515 – LM02 – Single Tank Level Monitor

The 515 LM02 application is designed to efficiently monitor and measure the level of product in a single tank. It utilizes the 4-20mA signal from a variety of level sensors such as pressure transmitters, ultrasonic sensors, and capacitance probes. The level monitor offers a 20-point strapping table and considers product density for accurate level to volume and volume to mass conversions. Additionally, it can display volume, percentage full, mass, and level, providing a comprehensive view of the tank status.

The instrument also features freely assignable relay alarms for high or low alarm conditions, along with an open collector output for programmable level control. A sub-menu provides detailed alarm status and allows direct access to change the alarm setpoints, enhancing operational flexibility. Furthermore, the availability of density correction for pressure level sensors demonstrates its capability to account for variations in product density, ensuring precise measurements.
