Flow Sensing Hot Water Distribution System

The differential pressure is kept constant by the main distributor of hot water flow regulation, the maximum flow rate will not exceed the constant flow.
The setting of each valve flow easily, the total flow rate is automatically adjusted.
Each valve rated flow set valve position by automatically every time you open, save, and navigate the set flow rate will be supplying as much as heating.

System Overview

The total flow rate can be supplied with hot water dispenser is allowed to flow only total flow of the set flow rate value of the open valve,
The main flow control valve is controlled by the flow sensor and control operations.

The distribution flow for each valve, to adjust the opening of the electric valve in each room.
Accordingly, the hot water distributor, the pressure difference is always maintained constant, the maximum flow rate to be supplied to the dispenser is controlled not to exceed
the sum of the flow rate distribution that is assigned to all the valves. (Constant flow function)
