Product description
The RESOL V40 is a measuring instrument with a contactor for measuring the flow of water or water-glycol mixtures and can be connected directly to the controller or calorimeter for heat quantity measurement. After passing a certain volume, the V40 reed switch sends an impulse to the calorimeter.
Applications
The heat quantity used is calculated by these impulses, temperature difference and predefined parameters (glycol type, concentration, heat capacity, etc.) Mounting is included.
