The Volumetric Level Indicator is designed to provide direct visual indication of liquid volume inside storage tanks. It works on a float and pulley system connected to a calibrated gauge or scale, displaying the exact liquid level in terms of volume. This system is robust, maintenance-free, and highly suitable for large and small tanks in industries such as water treatment, chemicals, food processing, and pharmaceuticals. Since it provides continuous and accurate volumetric measurement, operators can easily monitor tank status without electrical connections.
