Cryogenic gases, such as oxygen, nitrogen or argon, are used for a wide variety of applications and processes in industry, research, medical science and catering. The gases are liquefied by cooling them down to temperatures as low as –196 °C to separate them into their primary gas elements. The considerably lower volume achieved by liquefying the gases makes them easier to transport and store.

Remote tank farms are difficult to monitor. Critical situations requiring an immediate response can occur, for example when the filling level is too low, the tank overflows, the operating pressure is too high or too low, or when the vaporizer is overloaded. Immediate notifications that such parameters are outside their permissible ranges make it easier to remedy faults early on. In addition, safe operation is ensured and logistics are optimized.

When the Media 7 Differential Pressure Meter is used in combination with SAM DIGITAL, all parameters to be monitored are recorded continuously, the filling level and pressures are monitored, and alarms are issued when a malfunction occurs. Additionally, the data are compiled for further analysis, which enables plant operators to optimize delivery times and transport routes, draw up cost-effective delivery schedules and efficiently plan maintenance.
