The HERMetic UTImeter Gtex 2000 is a portable, gas-tight liquid level gauge designed for use on closed petroleum and chemical tanks. This advanced unit is ideal for verifying fixed gauging systems, performing temperature measurements, managing inventory control, and detecting free water in shore tanks. By connecting to a HERMetic vapor control valve fixed on the tank, the UTImeter Gtex 2000 ensures safe operation by preventing any gas release during use.
