MiniCal III - Bypass fitting

The MiniCal III is an innovative system with bypass fitting for monitoring ammonia and ammonium in secondary cooling circuits.

To monitor the medium, parts of the flow are guided through the bypass fitting as soon as the connected solenoid valve is opened. The medium is pumped back into the pipe, ensuring that no refrigerant is lost during this process.

The MiniCal III can monitor pipes in environments with pressures between 1 and 10 bar and temperatures between -10°C and +50°C. Service and maintenance work can be performed without disrupting the process. The pump and valve are continuously monitored for proper functioning.

The fitting contains a signal preamplifier and a microprocessor. It is connected to the central evaluation unit or a PLC via a 4-20mA output signal.

List of measured gases:

• Ammonia (NH₃)
• Ammonium (NH₄⁺)
