Tank level measurement and inventory control in palm oil milling
Reliably measure level, temperature and volume in crude palm oil storage tanks
Cost-effective Control of Liquid Volumes with Tank Monitoring System
Keeping control of tank inventory in crude palm oil production at a palm oil mill can be challenging. Crude palm oil is semi-solid so heating coils are used to keep the oil as a liquid. This places high demands on level measurement equipment else the bottom section of the tank cannot be utilized and storage capacity is lost.
A tank monitoring system is a cost-effective way to measure liquid level, temperature and volume, in order to gain control of tank operations and product inventory. With flexibility to connect a range of different intruments the system can be tailored to each tank – regardless of tank size, shape, or contents. An efficient infrastructure solution with a single cable digital bus saves wiring for a low installation cost. And when connected to an easy-to-use inventory management software the system reduces the need for manual measurement, improves accuracy, and helps prevent tank overfill.
