Notice of Article Publication in the December Issue of Monthly Waste Management
An article has been published in the December issue of the monthly magazine on waste. Would you like to "visualize" the contents of drums and containers? We are introducing "Laser Level Gauges (GDE series)," "Sensor Type Level Gauges (GDB series)," and "Air Type Level Gauges (GDA series)" for use with liquids such as waste liquids, waste oils, oils, kerosene, and light oil. These products are designed to be inserted into drums and operated with the push of a button, making them useful for transferring waste cooking oil and waste liquids from collection containers into drums. Traditionally, this involved tilting the can or peering inside. Our products streamline the process that previously required shining a light into the can or tapping it. They allow for measurements to be taken without interrupting the filling process. Please take a look!
