◆Overview：The meter is the one that is used to meter and display the heat released or absorbed by water flow via a heat exchange system and is composed of a flow sensor, a paired temperature sensor and a calculator (integrator)，The water volume value is metered by the rotation of its impeller and such rotation signal is converted into an electrical signal and delivered to CPU. The platinum resistor paired accurately collects temperature value information, and the calculator integrates heat or cooling capacity based on the two signals received within a period of time.

◆Performance characteristics:

☆The meter is equipped with a high-capacity lithium battery and a low power processor internally that can ensure the meter’s stable working time of 6 years.

☆The meter supports regular data storage and ensures no data loss after outage and power-on.

☆The meter uses high-quality forged copper material, with stable and reliable performance, long service life and corrosion resistance.

☆Its head can be rotated to satisfy the reading needs from different directions. Its LCD display screen can provide simple and convenient inquiry services, and its key switching operation is simple.

☆Circuit SMT, strict mandatory procedure inspection and high temperature aging testing can ensure the meter’s quality and long-term, stable and reliable operation.

※Based on order requirements, 32-40 temperature measurement ball valves or temperature measurement tee-junction parts can be provided, and M-BUS meter reading function can be provided optionally.

◆Working conditions:

☆Working pressure：No more than  1．6MPa（10bar）

☆Water temperature:  Cold water meter 4～95℃        
☆Temperature difference：3-75K
