Liquid coolant mass measuring system for refrigerating plant, has weight transmitters installed under condenser and coolant bottle/reservoir, to send weight values to chip card that informs centralized control system during low coolant mass

摘要

The system has weight transmitters (1) installed under feet of a condenser (4) and a liquid coolant bottle/reservoir (5), for measuring their weights and sending measured weight values by a wiring harness (3) to a chip card (2) for processing the values. Flexible tubes (6) supply liquid coolant to the condenser and the bottle/reservoir. The card triggers an alarm or informs a centralized control system at the time of low coolant mass.
