Sub-zero temperature fluids

The MULTICAL® 603 calculator can be adapted for mixed fluids and can operate in sub-zero temperatures, with a temperature range of -40…+140 °C. In applications where sub-zero temperatures can be expected, it is important to select temperature sensors and flow sensors with a suitable temperature range. Mixed fluids have a lower specific heat capacity compared to that of water. Kamstrup’s mixed fluid calculator variant can compensate for this and thereby provide precise measurements regardless of the chemical composition in the installation.

To ensure high accuracy regardless of chemical composition, the MULTICAL® 603 can compensate for the unique specific heat capacity in each application. Variant “M” (mixed fluids) is compatible with the most used antifreeze liquids, e.g., ethylene glycol and propylene glycol.
